Bad Disks Detected - Message
This evening heard my NV+ from the other room (yes, that far away) and checked it out. LCD screen showed Kernal Panic message - uh oh. Ran a memory test and after a few hours I see the NAS show up i...
Wanted to post an update to let folks know how this went. Picked up a USB-SATA adapter and went to the likely disk that was bad (#4, one that after reviewing email logs over the past year had reported on several occasions increasing Smart errors). Nothing I did however could I get the drive viewable on my laptop via the adapter (and it did have a separate power adapter). Thought maybe the drive was such a mess that it couldn't be mounted - so tried disk #2 (that had a single email alert during the past year - but one where the reallocation # jumped by more than a single sector as disk #4 had always done). Same result - could not get the drive to be viewable to run the software tools.
Decided to try the other two disks but was a bit depressed that my task was not going well. On disk #3 when I plugged it into the USB adapter, it powered up and made the squealing that sounds that drew me to the NAS at the onset of this saga. So on a lark, I went to the NAS and did a power-on with 3 disks and disk #3 out of the unit. Interesting enough it booted successfully, reported the correct errors w/ the disk gone and did a resync that completed this morning. Went to Frontview and checked everything out - all seems good. Now I am certain that before I started down this path I did a power on with 1 by 1 removing the 4 disks - hoping that I would identify the bad disk that way. Not sure if i was in too much of a hurry after trying the two 'obvious' disks and didn't let the boot process proceed far enough (that is a distinct possibility).
One last item to report - after the successful resync on the replaced disk - disk #2 (the one that had 1 reported reallocation count increase in the past year) reported a new one and jumped over 900!. Needless to say that disk is now out of the NAS and a sync is in process on the replaced drive. Need to replenish my spare drive stock now as my two spares are in the unit.
And lastly, to the question of back-up - yes do have a back-up, but it was slightly dated. I think I could have gone that route if had needed to and manually recovered most of the items not on the latest back-up if need be. After the 2nd resync is done later today, my last task of the day will be a new back-up and I won't ignore my back-up reminders again.
Thanks for the info and pointers - and if there is one take away for me - be patient on the first steps of trying to boot w/ 3 of 4 drives one by one as the first way to determine the problem disk.
