- This video shows how to replace a faulty RAID-configured drive that sits in a QNAP NAS.
This method should work in any QNAP which is configured in a RAID above RAID 0. The QNAP in this video is a TS-412. - แนวปฏิบัติและการใช้ชีวิต

Thanks. I always feel *_on edge_* when I need to remove a drive from my NAS while it's in operational... Nice to see your TS-412 is still running! Mine is as well, although now I use it as a redundant CCTV recording device.
I've since upgraded to the TS-453BT3, with a TR-004 RAID Expansion box. It was one of the drives in the TR-004 that got a few bad sectors after my suburb had a power failure a few weeks back. Anyway, nice video! Worth a comment & subscription... 👍👌
Had exactly same situation with model TS-459. Your video useful, many thanks
Thank you for doing this video. My drive 4 was failing and my biggest question was which drive was actually number four. Based on your video I confirmed it was the drive bay to the far right. Thanks!
Great video, very informative. I am going to be replacing a perfectly working 3TB drive with a bigger drive, so the question is if one of my other 3TB drives on my NAS fails in the future.Can I replace it with the perfectly working drive I will have already removed? If yes do I have to reformat it or will the NAS do that automatically? Or do I have to replace it with a brand new drive? Many thanks for any advice
Hi. Interesting question. Initial thoughts are that yes that should work, and the NAS should reformat the drive and include it in the raid automatically. But with that said, I have not tested that, or seen any official QNAP docs that deals with this question. It would depend on how the RAID-controller(or software) works internally. I know that on HP Proliant servers, the drives keep information on what raid, controller and drive-slot it belongs to. And the controller knows this too. This can be used for certain operations.
But I don´t think the QNAPs RAID controller is equally advanced, so this might be misinterpreted.
So in your case I would manually erase the drive before inserting it in the QNAP. Or just plug it in to any computer and create some new empty partitions on it. Just to remove any trace of the QNAP in it.
Then again. If you only remove one 3TB drive and replace it with a larger, you won´t be able to use that increased storage until you have replaced all drives in the array with larger drives. So if your plan is to increase the storage capacity of the array you need to replace all drives with larger.
And if one of those larger drives fail you can´t replace them with a smaller drive.
I hope that helps a bit?
I have my 8TB drive fail Sunday and the system is showing read only mode and im just waiting on the new drive to arrive. Im keeping my fingers crossed i hope all goes well. I just subscribed great channel.
Thank you! And good luck!
EXACTLY my same problem... TY Bro
Thank you for the good video. But... can I ask you a question...? :(
Actually, I'm Korean, so please understand me if my English is poor.
I replaced disk 2 yesterday successfully and disk 1 didn't today. I can hear the sound the HDD fan running in the machine, but It hasn't been recognized in the qnap application. These two old and new disks have the same volume of 2TB. What should I do...?
Oh, as soon as I knew this, I re-replaced disk 1, which was originally inserted, but even that is not recognized.........
Hi. I´m afraid I don´t understand the problem really. I would need more information about your setup and what has happened to perhaps help.
But for starters you say you first replaced disk 2 and then disk 1 the next day? Do you mean that you had 2 drives that failed at the same time? If so then you either have to have RAID 6 or 4 drives with RAID 1(10) and be lucky that the correct drives failed, otherwise all data on the drives are lost and replacing the faulty drives won´t help getting the data back.
But as I said, I need more information.
Does the Raid see the extra space you have on the added drive or are you only able to use 2,000 GB of the new drive. I have read that if you replace only 1 drive in a Raid, the system will not see the extra memory unless you replace all drives with the same added memory.
You read correctly. I cannot use the extra space until I have replaced all drives in the array with larger drives. After that I can do an expand of the RAID to increase the actual storage space.
@@thetinkeringdad Thanks for the confirmation, makes my decision to hold off until I can afford to buy all 4 drives at one time, clear.
@@timnels8638 Or you wait until the current drives become faulty and needs to be replaced anyway and then just put in a larger one, since you might have to. And when all drives are replaced with larger you can expand the raid. That or replace them all at the same time with larger disks.
mine is not rebuilding it gave me error like "unable to add disk 1 to the volume" one time also said that's because the disk is not big enough but it is, is exactly the same size as the others. If you do what you did and use a bigger hd are you going to waste space?
Some drives can differ slightly when it comes to capacity. And if it is smaller than the ones currently in the RAID it won´t work. I strongly recommend that you use the same brand and model of hard drive in each RAID.
And yes, if you put in a larger disk then the others then you are wasting space. But when you have replaced all the smaller drives in the same RAID you can expand the RAID to use the extra space. Read up on your QNAP model beforehand to see what its maximum RAID capacity is since there are limits to this.
And with regards to the error you described I also recommend you check the QNAP compatibility chart to see if a certain drive is supported in you QNAP model.

@@thetinkeringdad my nas is pretty old it's a ts-412 I bought it second hand with hd in it already all hds are 3 tbs each. 1 hd was a Western Digital and is the faulty one, the others are all the same seagate model. I bought the same Seagate model because I wanted to have a tidy nas with the same hds, my new hd is second hand too and it has 13000 power on hours which I think is good and it's similar to my other seagate hds which have alla around 10000 hours. The faulty Western Digital hd had 52000 hours. When I inserted the new hd and it got recognized I noticed a difference in the model number which is exactly the same but at the end of the model number there are two letters and two numbers, I checked and they should indicate the firmware of the hd ( I didn't even know hds could have firmware) anyway, my previous seagate hds have firmware CC45 while the new one is CC43, can that be the problem?
Normally when you look for compatibility list the just state the model not the firmware too so I guess it's not important. I opened a ticket with the QNAP support , the nas was working yesterday all the bays had blinking lights which as far as I know means that all the hds are working (writing/reading) but I was still seeing the volume in degraded mode. So I didn't resist and I unplugged again the disk 1 to try reinsert it or reinsert also di old hd and as soon as I unplugged it, the browser page of my nas closed and the nas became unreacheable. At some point I switched it off an on but was still unreacheable. I then noticed the status led blinking red and green (I thin because I'm colorblind) which I never noticed before. While I was updating my ticket with the new condition of the nas it became reachable again and the status led stopped blinking. I was happy and decided not to touch it anymore until the support will remote in it, but after a while I came back and the nas was switched off. On the browser the nas page was still open and I was able to see a notification saying "Failed to update system" which is strange cos I looked for update in the past days thinking that could have solved the problem and there wasnàt any update. There was also a background task notification saying "Media Library indexing". Now that I switch it on again it again not reachable and the status led has been blinking for a few hours...
Hello,
I have following problem with my qnap ts-253 Pro, This after placing a larger Hdd and reinstallation, In local network I can open or copy files to my PC so this works normally. As for my samsung tablet i can open mp3 and mp4 and in contrast i can't open or copy any pdf or jpg files. An error message is given: "Failed to download"
I have tried everything, user access rights settings are set.
What could be the problem here.
The nas has 2 bays on installing i had problems with the 2é bay.
So I Now there is only a hdd in Bay 1 (I don’t think this can cause the problem I have)
Thanks, Marc.
I don´t think this issue has anything to do with the hardware or drives, since you can access all your files from a PC. I´m thinking is might be that you have to enable some protocol in the QNAP that your Samsung tablet likes. Check what you have enabled, such as SMB, NFS and so on, and their settings. Perhaps the tablet accesses music and video files using DLNA at the moment?
Check the file management app in your tablet to see which network protocols it can use. I have no experience with Samsung tablets myself so I´m just guessing.
@@thetinkeringdad Thanks for you information, i will check this... and let you know..
I should mention that before I had no problem to consult PDF and photo files. The problem started when reinstalling the new Hdd
@@marc5820 Are you talking about via PC or from your tablet? And when you say "placing a larger Hdd and reinstallation" in your first post I assumed you did a complete reset of your QNAP? But perhaps you only replaced a faulty drive as I described i this video? If the latter then I recommend you check QNAPs compatibility list. But then again, if everything works from your PC then it cannot be a hardware issue. Check the settings I mentioned in my previous post. I can´t think of anything else.
Did it automatically replicated the data to new disk?
Yes, the replication started automatically within a couple of seconds from when I inserted the new drive.
Sir, what about data on it which you removed, you loose it or no?
Not really sure what you mean. The purpose of using RAID is so that you can replace a faulty drive without loosing any data. And also added speed performance. I would recommend reading up a bit about RAID and the difference between levels. But if you have for example 2 drives they should be in RAID 1, which means mirroring, then your data is duplicated to allow for one disk to fail and to be able to replace that drive without any data loss.
what about the datas in the disk?
As long as only one drive at a time fails, no data is lost. That is one of the main advantages of using RAID.
@@thetinkeringdad Thanks for fast reply. I have 2 drives. Both have bad sectors/read write errors and Raid management in degraded mode. I think it wont work for me.
@@ErenD With 2 drives you hopefully run RAID 1. Only other option is RAID 0 which basically is no RAID and then my guide won´t work for you. Can you access the data on the NAS now? And has any of the drives been marked in the NAS as Failed? If both drives have failed then I would think you can´t access the data. It is not uncommon for drives to have sector errors and still work since drives have extra sectors for this purpose and can remap bad sectors. If the RAID is in degraded mode, as you say, then I think one of the drives is Failed. I think you can safely replace that one as long as the other drive isn´t Failed.
@@thetinkeringdad My both drives has abnormal status for a more than 1 month but I don't have any problem to access my data's. The device is blinking red always.
@@ErenD If you can access the data, and you are using RAID 1, then you should replace the disk that the NAS says is Failed. Both disks can´t be failed completely. If none is Failed but only have warnings, you can replace both of then if you want. Just make sure you replace one disk at a time and have it fully rebuild before replacing the other drive. If you are worried about data loss then I recommend backing up the data to another storage first.
