Check HDD SMART for the effectve disk status, ensure to schedule or trigger a quick and a full SMART test.

SOme insight on why the HDD was kicked from the RAID might be visible in

[~] # dmesg
...

or the longer (stored)

[~] # cat /mnt/HDA_ROOT/.logs/kmsg
...

[TanGU]

Thanks for you reply!

Ahhh dmesg, i never think of that anymore, only looking into /var/log/messages (witch was empty)

I hope that can help you helping me ...

Seem that the disk failed ? It try to reschedule sector 8216 on the drive3 but it fail, thus marking the disk as bad ?

I am not sure what to do now, i am not sure if i want to plug the disk out, and in again risking a possible data corrumption? I also cannot do the smart test, when i select disk3, it showed as: "Hard disk does not exist."

What drive make, model, and firmware versions?

[TanGU]

What drive make, model, and firmware versions?

Western Digital Black, 1TB.

About the firmware version i'll have to check on it physically and be back to you on this.

[TanGU]

What drive make, model, and firmware versions?

Sorry

It is a Hitachi, 2TB, FW:580, P/N: 0F12117

(i forgot that i've changed the 1tb to the 2tb not so long ago...)

[TanGU]

SO, what do i do with this ?

thanks,

[doktornotor]

So, what is the drive model, finally? Hitachi, WD, or what? How about unplugging the drive finally and posting the exact info here, instead of useless confusing stuff?

Dude calm yourself down... take a walk or something...

See my post, i was sorry, and said the right stuff about the Hitachi drive.

Have a nice calm day to you,

[doktornotor]

See my post, i was sorry

Your post is still useless. Kindly see the compatibility list, get yourself comfortable with how a drive model number looks like, and finally post it here.

[TanGU]

Hitachi Deskstar 5K3000 HDS5C3020ALA632 (0F12117) <--- used google.

Now, can you help me ?

Yeah, sure (though not really sure what you used Google for). Since the HDD is on QNAP compatibility list and assuming this actually is the model you are using, kindly:

check HDD SMART for the effectve disk status, ensure to schedule or trigger a quick and a full SMART test.

as advised before (and still not done) and after these tests have all been passed OK and in case you still have problems, contact QNAP support.
