Qnap TS-563 2 of these drives Bays 4 and 5 have issues like everyone has talked about it.


Responce from Qnap
Hello again,

I have checked with our RMA team, unfortunately we don't have any part for this model any more, even Taiwan doesn't have the parts anymore.
and I need to inform you we are not able to perform any RMA for your unit since there is no part for this model any more.

They had me change out RAM Drives , check hard drives with WD software in another computer, which runs between 40 to 60 hours and found no issues.

TS-563 still being sold through B&H Photo , Amazon.

I can give more info if you have some contact that could help.

My QNAP response after sending them the Diagnostic Logs

--------------------------------
Disk-2 is very unreliable and its getting unplugged automatically or it shows failed.

We don't find any hardware errors in the logs. We would suggest you to replace the drive and check the rebuild completes ?
--------------------------------

The disk had past the quick Toshiba Diagnostic tool
Running the extended test - it had taken over 24hrs to reach 90% - not having used the tool before I wasn't sure how much longer it would take - so cancelled it.

Instead using Western Digital Data Lifeguard
Quick Test : Pass
Extended Test : Now running.

If it passes - I think I'll format the disk and re-insert it to see how the rebuild goes.
If it fails again - will try to get a warranty replacement.
Not sure what will happen if I try to return a disk with no obvious test fails.....

That sound like good strategy.

But if the WD test completes without error, please be patient enough for the Toshiba test to complete. 8 TB is a very large amount of disk to check and the long tests are exactly that, LONG. If the test have used 24 hours for the first 90 % and then use a relatively much longer time for the remaining 10 %, that would be a sign of a disk problem even if the test finally completes without indicating an error.

This thread exists because of the isolated problem that appear to be present on some batches of specific NAS models. That doesn't mean that all disks that are failing/unplugged from a Qnap are suddenly okay. In most cases that still happens because the disks have actually malfunctioned. Mechanical hard drives are by far the most error prone component in almost all systems.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!

A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.

All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

This worked for me :)
Looks like DIsk 2 had got out of synch somehow during the fail but it was trying trying to use it for the Re-synch.

Same issue here: TS-1263U-RP on firmware 4.3.4.0597 - lost four of 12 drives over the weekend after seeing the exact same behavior for a few weeks now. Support ticket opened after waiting on hold for an hour then finding that the voicemail box for support was full. Not happy, and definitely not buying another QNAP product for a client again. Thankfully this is a secondary copy of our Veeam backups here, so I am not out any data if the whole thing rolls over.

TS-563 here, disk 5 dropped out and started rebuild then kept coming back and knocking disk 4 out. Of course I'm out of warranty so this will probably be my first and last QNAP device. I paid almost $600 for this thing and haven't changed drives but once, so it's not wear and tear. My data is safe but I'm quite annoyed that I need to find something to replace it. There's nothing really comparable to this with the same horsepower at this price point.

Hi All

I have a QNAP TS-431P2 bought less than 2 months ago, with the latest firmware.

Few days ago I have put 3 disks inside, one 2.5'' seagate 500GB and 2 WD Red 3TB. All 3 were successfully used before for more than 2 years.
Now, after 3 days, got some warnings, then suddenly I have only one WD drive active, the other two are no more shown in the qnap disks dashboard.

Not having used the NAS enough time to lose data, but 2 disks is quite some money, and then, should I trust this device for keeping my important data?
What is wrong?

Thanks,
Sero.
