that haircut took a couple of years off Louis , he looks so young ☺️
The mask seems to make his voice sound less complainy too, or maybe it's just that the video is not about an apple product
I think that's a different dude
@@francischew4073 /r woosh
@@exlibrisas You spelled "r/" wrong
@@jamesbrown99991 You got the meaning regardless.
In German we say "seagate nicht mehr" wich when spoken means "she runs no more"
Just like Seagate drives hah
Like the Chevy Nova cars in Spanish, no va means roughly “doesn’t go”
Never heard this in Germany
@@jarlave9505 i did
@@markiangooley That one's silly. Chevy Nova didn't sell in Mexico because it was a POS, not because "No va" means "not going".
You should get a stethoscope for this process. Car mechanics use them to check injectors. You could use it to listen to the drive much better without putting your ear to it. Great video, love the time and effort that was put into it.
Like watching open-heart surgery (with less blood). And Louis as the family member hovering in the background.
Steve trolled by drive at 1:39:25 while Louis laughs in the background.
Louis sounds a little different with a mask on. Haircut looks good though.
also another nice point that someone else already mentioned: Much less whining and complaining.
These types of videos are what I really enjoy.
Just when you think that The Rossmann Group can't do anything better. They do more and entertaining content. I've seen repairs before, but never like this. Especially not so detailed with the software. Kudos! I love it!
Impressively clean "clean room area". Good reason for me to never attempt this work.
hahhah
You wouldn't get 15 seconds in without a bug landing on top of a platter lmao
You wouldn't get 30 min without snakes trying to eat the drive
Calling that a clean room is like calling a hamburger filé mignon
starshipeleven Sure you can call whatever you want a “clean room area”. So you tell me what ISO class that box have?
You can finally film the data recovery since it’s not next to the trash congratulations!
Seagate - where data goes to die.
Seriously! I've had too many seagate drives die on me to count! I do miss the old Maxtor days...Always had good luck with those. Ah well, sticking to western digital for now
@@gremate Seagate internal drives are much more reliable than external drives...
@@AaronShenghao i know that but im talking about seagate internal drives....Ive had a combination of both Western digital and seagate...I have about 30 enterprise drives for our servers in the office, 9 of them died and they were all seagate. The western digital drives are still going strong till this day.
@@AaronShenghao external drives are internal drives inside a case with a chip that converts sata to usb
@@something7877 Yeah the WD enterprises are a Tank! I still have mine up and running since 2011!
Love watching these videos
You have a great team member here
I find myself more anxious watching these repairs than the laptops
Anything goes wrong here there is a lot more to loose
more of this please Louis.
Craig Simpson The HDMI cables for the camera were just installed by Paul. Louis wants to do more of these.
Finally a data recovery video! Thank you! This is what I'm most passionate about.
Seems like matching date code is akin to other factors like country of manufacture and firmware version. I would think the other two might make for better assumptions, but he's the expert here.
Louis looking pretty fresh
David kim what's your favorite cartoon character?
@@joshwright8255 Why do you ask random questions?
@@joshwright8255 something you wouldnt know
He kinda quirky doe
That's not him, lol
I remember when we had to manually tell the hard drive to park the heads before shutting down the computer... and if you didn’t and moved the computer even slightly... bye bye data. I nudged he desk once with the computer off and caused a head crash. Trashed a load of Lotus 1-2-3 files I’d been working on. I was NOT happy as the guy who had been on before me told me “Nahhh, you don’t need to park the heads. They probably do it automatically.” But then again, in the late 70’s hard drives were notoriously fragile.
then there's me using SSDs as target practice
Low Level Format... Ahhh the glory days of being ridiculously happy if you got 70% of total drive space once formatted. LOL :) PARK
Iam_Dunn oh yeah... the wonders of low level format. I also used Norton Utilities to repair drives back in the 80’s. It was THE toolkit for sysadmins.
I would just like to point out something about the masks. I'm a farmer and I'm speaking from personal experience using these masks when dealing with chemicals. Those masks are only good for an hour or so and then they get wet. When they're wet the filtration is not effective anymore and all the air you are breathing escapes near your cheeks. You could leave them out to dry but that would probably defeat the purpose. Just a friendly fyi. Cheers and keep up the good work!
Covid masks are for decreasing how far droplets from your exhales travel, they don't need to filter. Cutting momentum of particles is enough.
@@_PatrickO They also work for germinating germs and cutting the oxygen level that gets into your blood while decreasing the amount of carbon dioxide that you can exhale... since some gets trapped in the space between the mask and your mouth and nose and doesn't just float away like it should. Not healthy for the long term. Don't wear one unless you have to.
@@_PatrickO While you are correct, you fail to see the other part of the problem. When the mask is wet all air is moved between the mask side and the cheek. So if for example someone sneezes toward you, their droplets maybe caught in the air flow while you are inhailing. But that would have to be a person without a mask. That is why it's not a good idea to wear a wet mask (at least in my use case with chemicals).
@@The7thCore You are incredibly stupid. When you put your hand over your mouth, the same thing happens. Hands are solid objects. Like it or not, it kills the momentum of the largest particles and thus contains most of what you exhale. You realize you are going on the internet arguing over a fake concept you are making up entirely within your own head, right? Stop inventing things to be outraged about.
Saw that this show up as an AD, clicked on it just to support!
Thank you so much for most comprehensive video on rosewood 😀👌👍👍👍. I was stuck up with sys file 93 and this video helped a lot. I am of opinion that those who subscribe to this channel might not need expensive acelab tranings anymore . You are such help to other Data recovery companies as well. Thanks again & Wish You all the best
Rosewood: rare exotic wood, the most prized varieties have few mature trees left. I suppose it’s like naming some junky motherboard Platinum...
I had an MSI motherboard modeled "k9N2 SLI Platinum"
It was the second motherboard I have ever purchased new.
or nicknaming a really fat person "Tiny"
My guitar is made from rosewood when i learnt it was near extintion i cried
I have a bunch of guitars with rosewood fretboards. It's funny in that world rosewood is considered the "cheap" and "common" option, whilst the more expensive guitars often have ebony fretboards or something like birdseye maple.
I like this guy, more content from him!!
Please make more tutorials on PC3000 and data recovery ! It's great stuff ! :D
After seeing all these Seagate videos I'm really glad I've been buying Toshiba ever since the start of my PC days.
Today I set a new record in holding my breath.
Good work
those double heads look like the breaker points on a Briggs and Stratton lawnmower I was working on the other day.
Glad to see you guys doing ads on TH-cam. Love your company
When I worked for a PC manufacturer back in the 80's, the Seagate drives always gave us a lot of problems.
IMHO I do question the quality of Seagate but I haven't used them ever since.
I do use mainly WD and never had issues with them, where some drives (according to SMART) been running for many years.
Interesting to see that without the spacesuit and extremely overpriced charges for some data-recovery companies, a good technician can do a very decent job in recovery/repair.
I guess the moto is when you do have a drive-failure and important data: pack it, label it, ship it. And do not touch it, do not screw (pun intended) with it anymore, leave it to the professionals.
Oh man, you can tell he's not used to talking to a camera, lol. I what him luck in gaining camera speak experience as Louis has. I still remember watching Louis and Linus when Linus came to visit to attempt a board repair for himself 😂
Not to sound stupid, but the "patient" drive was a 1RK172-568, and the correct donor ended up being the donner drive that was a 1RK172-568 while the incompatible donner was a 1RK172-070. Wouldn't this be a much better "guess" to use the actual part number vs. a DOM?
So happy to see a full-length HDD repair video!
I have lost count of how many failed seagate HDD I have replaced in friends and family computers. WD for me or a quality ssd like crucial or intel
I had plenty of great Seagate drives... 20 years ago.
@@JimAllen-Persona Once again capitalism and cheap manufacturing reared its ugly head.
The old Seagate IDE drives were indestructible. Even the first SATA drives were great. But they have gone downhill.
WD is using SMR tech even in their WD Black series and NAS Drives and low capacity PC, laptop drives as well without informing anyone. Loads of people were complaining of no or low write speeds and it took a shytstorm for them and other companies to own up. But it's the shittiest company out there right now.
TH-cam recommended this video to me as an ad. Niceeeee!
The Doctor gets shot in the End Lmao
This is the length of a feature movie and the content is watching a man fail at recovering data off a hdd for most of it... But a happy ending
ronald rogerson And Louis is the proud father hovering in the background.
I went to Hogwarts for this and learned Data Recovery Spell... "REPAIRO"! Fixes any hard drive in no time... easy peasy. 😂🤣
Just watching this video made me looking at my decade old rosewood drive in suspicion, and immediately checked their SMART.
Uncorrectable error..... 0
Power on hour...... over 3 year
okay, I guess it should stay, for now.
Yeah don't get worried by those who say that they are all dying. It may be quite a few but there were millions of units manufactured, the chance is still very small. But you should backup on another device anyway, at least every few months.
This is the type of yt add I’d like to see
Very informative session, thank you dear Louis.
What is that QR code on the pre-amp connector? Does it help at all to identify the correct matching one? ^^
those are usually codes so scanners at the factory can verify that it's the correct component
It appears to be the part number, which matches the drive marked 8202, and not the C202. The C202 also had different firmware indicated. If I had to hazard a guess as to which was more likely to contain compatible parts, I personally would have gone with the 8202 donor first despite the manufacturing date/location info. I skipped around a bit through the video, as it was a bit too long for me to sit through the entirety... which head stack did he end up using, the C202 or 8202? (Later Edit:) Oh, wait... I misread your comment, you said pre-amp connector, not drive. Yeah, I missed seeing that one. Good catch, now I wonder, too.
Very useful and important videos, but an important note, if possible, before opening the hard disk, try it on the computer so that we can take an idea and complete the information and understand when what cases require opening the hard disk and if it is possible to try it also after repair. Thank you very much for your valuable time and your valuable information.
46:40 "what the drive is drawing in" - I once had a Seagate drive which fell off a table to the carpet below in a HDD case whilst powered up. It worked nearly normally as a low priority stuff backup drive for some years and then suddenly began clicking. I was about to replace its PCB but suddenly it came back to life once powered up by another PSU. I then checked the original power supply from McAlly and found that it fails to power up most of another HDDs I had back then. So the real reason behind was a PSU deterioration that began to deliver less power than necessary.
Why were you going to replace it's PCB if it was clicking? That would be a read/write arm problem.
I had the same issue with a PSU that was too weak.. sadly i was a dumb kid and thought shaking the drive would help it spin up... My first headcrash...
Can you make a video on working with hybrid drives? Also I know Seagate is bad but I have had worse experience with HP "brand" drives, Seagates are not the worst out there; I can say (in my opinion and from what crossed my table the least) Western Digital are the most reliant for recovery.
At 1:01:28 he says that since initialization is taking too long, it could mean the heads are incompatible. If thats the case, why are there background activities running shown in the multimeter and terminal? With the incompatible heads, shouldn't that be impossible to be happening?
Wow! Another fascinating learning experience from stevesavers.com and the Rossmann Repair Group
is there a chance that those preamps are more related to manufacturer country rather then the date? 'Cause one is from China second is from Thailand
howd i miss this video, ive been hoping u were going to do this kind of video after the move!! thank you so much!!!
me an hour later: wait thats not louis, my thank you still stands!!! im a lil deaf sorry dude
Hey, I was wondering where did you learn data recovery? Did you learn by yourself? As a computer technician, I do some basic data recovery but would like to learn more about it, where should I learn all of this? Thanks!
Nice video. Suggestion to Steve, stop adjusting the zoom out. Youd get the drive so it was full screen and we could see detail then for some reason youd zoom out and we'd have half a screen of ss bench!
I can tell Steve knows his shit. There is hope. Keep going guys!! Love it.
This is a great explanation why data recovery is expensive
hii man .
in Rosewood drive before you do bad heads or glued heads just unscrew the pcb , patch it and then turn it on . its saves you on\off procedure in the begging witch can be critical in this drive. (just my 5 cent form pro to pro :) )
Wow..i always amazed the way you handle the hard disk, its like a bio lab. Here in my area, "computer technician" handle the hard disk like a toy, no gloves and dirty table
Wow. Reading the platter one micron at a time. Oh, the alignment woes! :-) Can't do that with a wrench.
I have suggestion for you. Kind of educated guess. When you worry about type of preamp used in any of those mechanical HDDs, you probably shouldn't. Try replacing the headstack along with the control board it came with, and swap the EEPROM from the patient onto the donor part. I am pretty sure control boards will have different part number difference for each specific preamp. Are you getting my idea?
Damn, I could not find the comments for a moment. Damn TH-cam fixing what’s not broken again.
Is it me or did Seagate hard drives get less reliable when they moved manufacturing from Thailand to China?
There are alpha bars that give off positive ions that can eliminate static on surfaces that you can mount over head
Finally, a proper Steve video
I have always wanted to see how a hard drive inside are and how it works and cool for making this video.
I watched this entire video. What a ride! I did notice one thing - the labels on D2 and Patient are very similar even though DOM are significantly far apart. The layout of the text, barcodes, etc., and specifically the areas of white space was much more similar between D2 and P than was D1. (See 1:15) Maybe that can be an indicator to watch for in the future. Take that with a grain of salt as I am not a recovery tech :)
Louis got a Radical haircut!
Great video BTW, new place looks great! Old one reminded me of some back alley bunker in Siberia.
I check every hour on this channel to see if there's another live stream with the qt who cut hair yesterday
You mean his girlfriend
34:41 -- "Make sure you can move it... ok, so you can't move it... something is stuck here"
TBH my heart kinda started racing a little when this happened, and I'm just watching it!
I'm probably not cut out for clean room hard drive repair. 😂😂😂
With PC3000 better first step to swap to Engineering test firmware. It allowed use more command like heads parameters adjustments for better fast reading and bad block correction.
Also highly recommended stop MEDIA CACHE process in firmware.Do not turn of just stop it. Need turn of recalibration process (firmware flags ), turn off fast move heads operation, and turn of write. Better for rosewood create media cache table and user table and after combine it with MC table list in Data extractor rosewood plugin.
If hard drive do not starting itself then upload firmware in memory use SATA and after leave translation system only for fast and better data reading.
Questions ? ready to answer.
How come Russians know all the top HDD and firmware secrets ? :) BIOS too. Thanks for telling it in english. We need the help comrade.
mrlithium Russian have good hackers. They can do firmware reverse engineering. Some Russian working in Seagate technology and WD like developers and provide some service manuals and sources for ACE lab. in Russia, the law does not prohibit making changes and modifying the program code (firmware). However it is prohibited in America. :-)
Very good job this is one of my dream job, thanks for sharing 🧤🧤
Woah I got an ad for this video
Shouldn't you wait to open the patient to confirm the preamp before opening the donor?
If Steve were an architectural engineer:
"The paint is really the only thing that holds this whole bridge together. I mean, aside from millions and millions of rivets"
I may recommend taking a picture, and/or writing the model/serial number of the drive on the enclosure.
louis! .... this is good, fresh interesting material ... not just another smc/cd3215/jtag or your usual stuff . rekindle our interest in watching people repairing stuff ! (and ban kopaz please lol)
credits to the guy that did the work and comentary
37:33 when i work with so thiny screws i use to handle the screwdriver down near the end ,but not at the handle.It is way safer and more precize.The handle is for giving power wich is not the case here.
22:49 - Love how you just say 'woah' after you nearly fucked the platter but then didn't say anything afterwards, like "Kids, don't do that at home"
or even "and that's why we start with the DONOR Drive!"
Instead of ear contact, use a stethoscope?
Oh to have Seagates. Our supplier uses Toshiba drives and they are juuuuuuuunk!!! Loads of them DOA and so many failed under warranty. I am tripping over stacks of bad drives. By far the worst I've ever had to deal with. Luckily we usually have the privilege of not needing data recovery. I'm fairly successful at force cloning them over a day or two if need be. Otherwise, I toss it on the pile of Toshibas and figure I'll get around to scoring some more magnets later. Best drives I've worked with so far, Fujitsu. Almost all of them are making it to 60,000 hours and I have some still running fine at 90,000+ hours
This guy peels off hard-drive like he has been a sata cable in a previous life :)
A lot of tools I don't have. I have an external drive that takes hours to be detected or not. Tested outside of the enclosure too, but hot connect was not detected in windows and I didn't test any further.
The only ad ill click on is a rossman ad
Could you please do a PC3000 tutorial as slow as you did the drive repair.
The part with PC3000 was kind of chaotic in this video... at least for me.
Google finally let Louis have his ad
How do you dismantle it without shredding all the screw heads?
These things arrive done up so tight I can never get them out without a drill.
Good old trusty Windows 7 - A compatibility king!
He's done with the second swap at 1:26:35
What an incredible talent you have.
i actually enjoyed this its great to know something new
More of these videos please. Thanks Steve
the problem was all the time the disordee to check before (before do anything) the checkbox at indirect…. the order od the settings is here prior
as a total HDD recovery noop i have to ask, why one shouldn't plug the repaired drive in a normal computer as 2nd drive, and copy and paste the data form it, instead of using a PC-3000 software?
I have basically the same question, how risky is it and is there any chance it will just work if you have the compatible head assembly. Thought about ordering two identical drives and practicing swapping those but don't know if there is any benefit just being able to do that without the PC-3000 system.
It's because of the way the OS accesses the drive. If it finds a bad or slow reading sector it will try to read it over and over and likely destroy it and then shut down. It also moves the head back and forth over the drive trying to recreate each file from data spread over a number of sectors. Data recovery software simply takes an image of the drive starting in the beginning and moving to the end, or in reverse. It can also time how long it takes to access a sector and will skip it if it looks suspect. It can read the good sectors first and then go back and try to access the bad ones. That way it doesn't risk trashing the drive before it has all the good data. Also hardware, and some software data recovery solutions can reset or restart the drive if it shuts down due to a bad sector. An OS won't do this, it will simply shut down. Basically put, an OS is designed to respect file system integrity. Data recovery software is designed to respect data integrity.
PC-3000 has special procedues and secret algorithms to access it. A lot of top secret info is put into making it, and you have to pay to get access. Its not the regular kind of software. You would fail or damage it more if you tried without it. This needed to be addressed in the video, or people will be confused and ruin their drive trying it themself.
I know this video is kinda old but you can edit sys file 93 in RAM first, to disable background processes, and then edit it in SA.
What was the point of trying to get the drive to write?,.. if it's reading correctly, and the object is data recovery, as soon as it reads, I'd be start saving the data to another drive
I need this kind of patience level
This is excellent. Appreciate that you're seasoning and bringing in talent that can teach from a new place of knowledge.
pigtailsboy ....You know that was Louis with a mask on.... right?
edit: uuugh ...nevermind, I’m stupid. This is some guy called Steve... LOL He sounds like Louis.... :/
I remember the early days of glass platters for 2.5 HDDs. I had a customer come in with a drive, that the planter had shattered.
Seagate, the best unexpected encryption you can buy.
I have like 13 drives I'm sitting on. I really want someone to do data recovery.... This is insane amount of work for one drive. God damn that's scary.
I need my western digital 4TB drive repaired. It was dropped on the floor one day and it no longer works. It powers up and tried to read but it completely stops.
1:00:33 Starts with "Alright - I Think . . . "
Monents later, drive has heard someone wants sector access, and audibly lolz the human.
Priceless.
Y'all aughta have your own "right 2 rip-pear" .pizza extention. If you could e-mail NY pizza, techs the world over will have met heaven on earth! Right now, the only place to get NY pizza is . . . you have to go to NY to try it. You have to LIVE in NY to make it a part of your diet.
Much love and respect to the entire team.
I have a few questions.
1. Where do donor drives come from? Are they working drives pulled out of salvage machines, or are they brand new drives sold as surplus in bulk, or something else? If they're new retail drives, I can see why (other than the highly skilled labor involved) drive recovery is so expensive! If they can only be used once, every time a donor drive is used that's the price of a new drive.
2. Can the heads from one donor drive get used more than once? How are they stored, if that's the case? Do you simply put the heads back in the donor drive for storage?
3. I wonder about head registration - here there are two heads, the tracks on the platter are tiny, it wouldn't take much for the heads to get out of alignment, I'd think... I hate to think of how difficult this would be with multiple platters.
4. You mentioned that you needed to check how many platters and heads there were in the drive. Did they actually make this model of drive (1 TB Rosewood) with differing numbers of heads and platters?? I can't imagine fitting more than one platter in that enclosure. Or were you talking about drives in general? I am amazed that they could actually put one terabyte into a one platter in a 2.5" drive.
In any case.. I suppose it's a real lesson about why backups are so important. A LOT cheaper and a lot less hassle than having to go through this. There's a proliferation of cloud storage solutions these days, too - Google Drive, Microsoft's One Drive, Dropbox - and they're getting easier and easier to use, though they also have their issues.
1) working pulls from salvage or used on ebay. they dont have to be perfect, just good enough
2) yes. they might even leave them in to save time, and once recovery is done, the patient becomes a new potential donor. customers old drives are usually not returned to them once recovered, because a brand new drive is purchased to store the recovered files. After all that work you don't want to send them back with something of questionable lifespan.
3) there is a dynamic calibration process built into the firmware by seagate. you can also view head calibration data or make power, preamp, servo or other changes manually but he didnt even bother to look at those. which might have revealed clues why it wasnt reading at first. There were probably about 10 other things he could have double checked instead of repeating the same 3 things over and over. Also the fact that background re-allocations were succeeding was another big overlooked clue.
4) most likely a general statement. you dont want to go by "1TB Rosewood" anyway. thats too general, you want the full model number ST1000LM035-1RK172 specifically the last 6. Worst comes to worse you can try a mismatch, but I wouldnt. There are families of drives, in this case "Rosewood" codename for short, and they often turn high end drives from that family into lower end ones by removing some of the heads and platters, like a 2TB that failed validation at the factory into a 1TB.
What is not mentioned at all is that "PC-3000" does all the software work for you and is the license is extremely costly, $2000+ dollars a year. Even if you physically did the head swap yourself, you would most likely be unsuccessful at home. Seagate has also locked normal users out of the serial terminal so you need the tech unlock handshake code. Louis should make more videos explaining why you should invest in his data recovery service rather than deluding people into thinking they can do it themselves from one video. Louis did say it was his new mission to demystify Data Recovery in 2020, like he did for Macbook Repair already, so I guess this is part 1 of N....
