Hello
Disk 1 has failed in my TS421 with 2 3 4 working in degraded mode, I have installed a new disk and run a file system check and i get an error message saying failed to add disk 1 to the volume. I have
(all 4 disks are showing as good)
Deleted all partitions from the disk
rebooted
Tried to add disk 1 as a single disk - didnt show up in create box
any ideas on next steps
Thank you

Re: Hard Drive Failure
ok the RAID5 is degraded
- remove the new drive
- format the disk (quick format is fine)
- reboot the NAS (it should come up degraded)
- insert the new disk again and the rebuild should start
the same command should give you info about the progress of the rebuild

Re: Hard Drive Failure
Ok I think this is a compatibility issue, I replaced disk 1 with a WD30EZRZ 3.0TB Blue Desk Top Drive...When I put the original disk back in WD 3.TB Red NAS Drive (With a deleted partition it worked almost straight away so it must be a disk problem? Strange thing is I deleted the partition on the original disk and put it back in the NAS and the volume with all 4 disks was availble within in minutes I was expecting it to have to rebuild that HD back into the volume

Re: Hard Drive Failure
the blue drive should be recognized..it's just not meant for raid use and could fail prematurely (or make the raid slow with long error corrections)
on raid1...all volumes/folders should be visible, even when degraded
