TS 210 RAID 1 - trying to replace disk

Have you tried both disks ? If the RAID is damaged now, that would explain why the rebuild did not start. While you try the recovery, no disk should be active in the QNAP.

I have extracted one of the drives from the QNAP and linked it to a PC to read it. The message about the damaged RAID is in the LINUX reader program that I use for ext reader in Windows, not in the QNAP. QNAP’s web interface loads the migration page…

The QNAP should not be on right now … as said, try the other drive

So after initialising again the QNAP, and setting everything up with one of the old disks, upon adding the new disk once again I get “disk does not exist”.
I see other people had the same issue. I did what was advised - turn off and unplug, replace sata cable - none worked. Any ideas how to get pass this? Or should we consider that model incompatible?

Just to add I have checked the new disk with various tools, it is in perfect condition, SMART info all accessible, so it seems that it is just the QNAP software that has a problem with reading the SMART info. If QNAP can not see the SMART info - can it still understand if there is an issue with a hard disk when there is one? I mean the disk is working fine, it is just that this info is not accessible to the NAS, so… I could use this new disk and schedule regular tests for it in the QNAP interface, so that if there is a problem it would notify me.

BTW it is kinda sad to see this community here nearly vanished, what happened?

This community is brand new, so not many people know about it yet.

That NAS of yours is 15 years old, so it could be that you found an incompatible disk model

I opened a ticket and I was told TS-210 is no longer being maintained and supported (as expected) and they can only guarantee that compatible HDD on the TS-210 compatibility list can work properly, but I could still use the WD80EFPX since it is detected and the volume is mounted correctly.

What would be the today’s equivalent of TS-210?

The TS-133 or the TS-216G

QNAP, TS-133

QNAP, TS-216G

Thank you, Becker2020, I was just looking at 216g and 233. I don’t particularly need to have directly accessible drives, so TS 233 ok with me, it is a bit cheaper while having almost the same stuff, what do you think about it?

I think the TS-233 is ok

I prefer the Intel-NAS (TS-264)
