Disks missing but still physically there?

Post by krilbe » Thu Feb 04, 2016 11:37 pm

Suddenly our TS-219P reports "Hard Drive Missing", "Install and format at least one hard drive before using the NAS. [...]" when I go to the device's webpage. But our two disks are still there and we haven't physically touched them in any way.

Yesterday we installed an upgrade of the system software and added a user. Our continuous backup program reports has successful backup yesterday morning, so maybe something went wrong when we did those things.

But what do I do now? I can't even log into the device because of that error. We've tried to restart it w couple of times with no effect.

If a drive goes bad and keeps reporting problems, the system 'ejectes' the bad drive. so the warnings go from bad i/o to drive missing.

But we have not seen any warnings at all.

Apart from that, there are two disks in a raid 1 config (mirror), and it seems odd that both disks would just die simultaneously.

How can I examine the disks or get the TS-219P to "find them" again?

Well I got it to start again at least. I ejected the drives and reinserted them, and restarted the NAS again.

There is a single warning about the file system, so I will run a file system check.

Also, it seems to be having network connection problems. I can load its website on occasion but often get disconnections. Perhaps it's time to disvard this unit....

This could indicate a coming-up hardware failure, ie. on the power supply or the internal voltage regulation not being able to provide enough power to recognize / spin-up the HDD.

Seems plausible.

If I'm unable to copy the data from the disks using that unit, what do I need to extract all files?

I assume I can put the disks into a different QNAP NAS?

What if I want to switch to a different brand?

We don't have any Linux computers, only Windows.

A qualified yes. Go through the manual, which lists all of the variations of what QNAP NAS models can take the drives from a different QNAP NAS model.
