I don't think I've ever had something run as poorly for no reason as the partition assistant did, anytime I clicked on disk surface test it did nothing and would almost crash constantly even when I wasn't doing anything on it
Guide is nice but unfortunately none worked for me. When i try "Situation 2 - Method 2 Check Bad Sectors" it doesnt do anything. For other working drives surface test window opens but no reaction or error for broken drive and previous fixes didnt do anything than pop error every time. Disk part show that drive 5 which is broken one is online but nothing works. I've tryed couple of things in that app of yours and it replyed with errors 6 and 45 and i got nothing. One thing i didnt try is switching to another cable but since i dont have any other cables to try im boned on that one for now. Im gonna try accessing that drive from windows install program and i might try rebooting into that screen where you set up for windows safe mode (good old times when it was accessed by F8 right after bios) tomorrow but something tells me that wont work either, i guess that 2TB external drive is gone for now.
The details help me, though my part when I tried to do the disk management part when I tried to do the MBR part gave me a "Data Error (cyclic redundancy check)" message and I'm not sure how to fix that part.
this is NOT a freeware. You will install, then it will show up the windows screen to proceed on acquiring an extremely expensive license to run with it.
After Initiliazing my external hard disk and trying to convert it either to MBR or GPT, it gives me an error: "The request failed due to a fatal device hardware error" - what to do now?
For me when opening disk management, its not opening. Just showing opening Virtual Disk Service. Once it got opened, then I tried MBR for initialization, also GPT...in both cases semaphore time out happened...what to do...need help guys
Thanks so much for your tutorial, but unfortunately it didn't help. I was looking for a solution for my 2TB Seagate Portable HD which stopped working. It's beeping and it shows "not initialized" plus "unallocated" on Disk Management. Also, Disk Management doesn't show its capacity properly, like it was 134217728 GB. When checking it on AOMEI Partition Assistant, it shows 0KB and 0 partition. The program shows an error message when trying to recover this disk. Nothing happens when I click on "surface test".
I have this same exact problem with same weird capacity number for the same external Seagate 2TB HD. If you've figured out a solution, please let me know.
@@AruanaACN I tried taking the portable shell off the HDD itself where the sata and power outlets are now exposed but I think I may have messed it up more. It won't even be detected on any level now and instead gives a beeping sound. Be very careful in taking the HDD out if you choose to do it. It was more difficult than I thought it would be. I haven't yet :( The only solution I think is to send it in for an expensive repair. I'm considering Luis Rossman because they seem the most honest.
Sadly the drive does not show in your Software and I can't do anything in diskpart because it thinks it has a size of 0 bytes. The only tool that sees it correctly is testdisk, but there I can't write anything either. The problem was the result of an empty battery during a full format using windows Partition Manager, so I don't need any data back. Is it possible that the hardware got damaged due to the sudden power loss during writing?
It is possible that your disk is a little damaged due to the sudden power loss during writing, Here my suggestion is to try to fix it by running the CHKDSK command and if it is not working, then try the methods in this article. www.diskpart.com/articles/sandisk-usb-repair-tool-7201.html This article is not only suitable for SanDisk but also for other branded disks.
When I tried initializing in diskmgt shows an i/o device error on my external drive (luckily). Will rebuilding mbr get the disk back online with all the data intact though.. if not, whats a good unpaid data recovery software
Shut down your PC and use a fine tool, such as a needle, to clean the ports on the hard drive and both ends of the connecting cable. After leaving the PC powered off for a few minutes, turn it on without the drive connected. Once Windows has fully loaded, reconnect the drive, and it should appear normally. If it’s an internal SSD, leave it disconnected, power on the PC, then shut it down again. Reconnect the SSD and turn the PC back on to check if it is recognized.
When you try to initialize a hard drive via Disk Management and receive an error message such as “This request cannot be completed because of an I/O device error” or “The device is not ready”, the usual cause is that there is something wrong with the hard drives connection cable. You should adjust the drive's connection cable and try to initialize it again. Where possible, we recommend connecting the hard drive to another computer to see whether it is able to be detected and initialized.
Hi, My External 4TB Hard drive shows ''unknown'' and ''not initialised'' . It doesn't show anything on the volume. It doesn't show on ''This PC'' . It indicates '''Data error(cyclic redundancy check'' when i try to initialise. Kindly help.
So I dropped my EHD earlier today and didn’t think much of it. It’s wasn’t that bad a fall but it’s showing this error and I’m trying to figure out why it’s not readable. The cord works fine and it’s showing power but it isn’t doing the blinking thing as it’s starting up. It’s just staying on powered on.

I converted my internal HHD to external HHD using the converter case. Its not accessible but its showing as Unallocated in Disk Management. Can I use the same method shown in the video to access the data on it. *There is very important data on it.*
If you initialize it, it will cause data loss. But I'm not clear with your disk status, you'd better send your issue to AOMEI support team via email with a screenshot of your disk's status.

you said there will be no data loss if we rebuild mbr. But it's still showing unallocated space. I have 700gb of data in it, and I wont be formatting it.
Rebuild the MBR will not 100% fix the problem but 100% will not cause data loss. If this way doesn't work then you will have to initialize it directly and that will cause data loss.

Hi dear, if it is logically damaged, you can reuse it after rebuilding or reformatting it; if it’s physically damaged, it means that it has lost the ability to write and retrieve data forever.

Hi, the only thing you could do is back up your data, and see if it can be restored on a new disk. You can backup and restore your data with this tool: www.aomeitech.com/llyy/download/aomei-backupper.html
Didn`t fix the issue with my WD Element. I can not initialise it by an hardware error. It is a new disk, never used but was laying for a long time in a cupboard.
Shut down your PC and use a fine tool, such as a needle, to clean the ports on the hard drive and both ends of the connecting cable. After leaving the PC powered off for a few minutes, turn it on without the drive connected. Once Windows has fully loaded, reconnect the drive, and it should appear normally.

AOMEI doesn't worked, tried click surface test and nothing pops up - also at the end of the video you didn't bother to explain what to do next after getting the data from the surface test?
The surface test can only tell you if there are any bad sectors on the disk, then use the check partition to fix them but the physical damage cannot be repaired.

Hello, when I rebuild the MBR, all is ok, but there is one thing i don't understand, I have a 4To external Western Digital Red Hard drive but on windows i can see that there is more than 4 with 3 partitions of 1.96To ?!? when you rebuild the MBR how can you see the external hard drive, i need to attribute a letter or... what's the next step ? thank you
Do you mean how can you tell which drive is your external one? You can tell by their drive letters.
@@AOMEITech nope i just mean when i build the MBR what's next step because i can't see with my C:/ drive and when i want to add a letter to it and mount it, the option is grey but the MBR was built successfully
My disk is visible in disk management but not in amoei partion assistant 😭😭
🤣Have no idea about that either.
hey my problem is when i start computer it shows hard disk in startup but i cant see and use hard disk in my pc and in disk management, the files are still there for eg if i try to open the app which was in that disk it says: windows is searching for needforspeed.exe locate the file yourself by pressing browse, and on some apps it says application not found, plz help:(
Hi there, I've never met or heard of an issue like this before. I think the issue may be a disk error. You may look for a local repair shop and ask for advice or you can try to contact the manufacturer or the outlet of your computer.
@@AOMEITech oh ok thnx for reply
Oh and also do you know anything about paging file, when this problem started now when I start my computer it says Windows created paging file...

Have a scenerio where disk is unallocated and cant initiate drive with fatal disk hardware error been trying all day to fix it to see it itll operate but no luck ive tried disk management diskpart uninstall drive disable update driver which just gives me the statement of im already using recommended driver so any tips
ive try with disk management,but when i choose mbr there is an error said "access is denied"
how do i fix it ?
you said there will be no data loss if we rebuild mbr. But it's still showing unallocated space. I have 700gb of data in it, and I wont be formatting it.
Rebuild the MBR will not 100% fix the problem but 100% will not cause data loss. If this way doesn't work then you will have to initialize it directly and that will cause data loss.
@@AOMEITech my mistake. I initialised before watching your video. Now I'm using a data recovery tool to recover
I have 250gb Seagate hard drive I had swap pcb and also swap bios but it shows as 0 disk unknown not initialise. On right click it give option to initialise with MBR and GUID. What will happen of I chose MBR will it initialise and I can see data? Without loosing data? Pls assist.
If you click "Initialize" it will cause your data loss, you are suggested to try "Rebuild MBR" first.
with the same case as the video above. but my hard drive capacity does not match. my hard drive capacity is 1 TB but it reads 131 TB, how do I fix it?
It reads 131TB? Are you sure it's not 131GB?
I have a problem with this as well ... After i used the first option, it still showed uninitialized albeit online.... I tried using attributes disk clear... that didn't work, formatting didn't work as well... It showed i/o device error
Please help
Can you initialize it directly in Disk Management, right-click on the partition and select initialize.
What if my external drive has damages after trying the surface test? Is it possible to be fixed? :( My drive is connected because it blinks and makes the "connected sound" whenever I connect it to my PC but it cant be recognized.
Hi dear, if it is logically damaged, you can reuse it after rebuilding or reformatting it; if it’s physically damaged, it means that it has lost the ability to write and retrieve data forever.
I try both steps but still is not working it says "data error(cyclic redundancy cheek) in the second step disk management please do have idea concerned the case. N.B transcend...

There is nothing to do.. My WD hard drive is gone.. Too many damages check with AOMEI PA.. How can i do? I don't want to lose data that is very important for my life.. Would you help me please?
Hi, the only thing you could do is back up your data, and see if it can be restored on a new disk.
You can backup and restore your data with this tool:

Didn`t fix the issue with my WD Element. I can not initialise it by an hardware error. It is a new disk, never used but was laying for a long time in a cupboard.
Shut down your PC and use a fine tool, such as a needle, to clean the ports on the hard drive and both ends of the connecting cable. After leaving the PC powered off for a few minutes, turn it on without the drive connected. Once Windows has fully loaded, reconnect the drive, and it should appear normally. If it’s an internal SSD, leave it disconnected, power on the PC, then shut it down again. Reconnect the SSD and turn the PC back on to check if it is recognized.
during surface test red blocks are showing.... is there any way to rectify if the disk is damaged?
th-cam.com/video/AQlRoOc1lLU/w-d-xo.html&t
AOMEI doesn't worked, tried click surface test and nothing pops up - also at the end of the video you didn't bother to explain what to do next after getting the data from the surface test?
The surface test can only tell you if there are any bad sectors on the disk, then use the check partition to fix them but the physical damage cannot be repaired.
