Having a hiccup with my NV+
Hello. Long time user on the NV+, will be needing some help with a hiccup I'm experiencing.
I checked the HCL, the Caviar Green is in fact on it.
Extended tests are complete.
Disk 2 had a small number of bad sectors - so I repaired those.
I tried firing things up after that - still a no go.
My first attempt at scanning disk 3 resulted in the most serious warnings I got.
It initially failed quick and extended tests, citing too many bad sectors - I was initially excited: yay, let's just replace the drive.
Wanting to rule out a bad seating in the hard drive dock I was testing it in, I tried it in the other bay.
My second attempt at scanning disk 3 resulted in passing both tests.
Disk four passed everything uneventfully.
Firing up the NAS after all that, I was fortunate enough to access to my files again.
I'm furiously backing up GB's and GB's of data now (my own doing, I realize - I deserve this discomfort).
I realize the sage advice would be to do a factory reset, start fresh, and hopefully restore some faith in this device.
Given that it might be a few days/weeks until I round up 3.5TB worth of storage (and the time) to do the right thing - how freaked out should I be about this problem returning?
I know the core message will be "you fool, your NAS is not a backup", but if you could shed light between:
- Hard drives do this from time to time, repairing the odd bad sector is a part of disk maintenance but it's not indicative of imminent failure and repaired disks can continue in a RAID5 environment where single disk failure has been planned for.
vs
- When hard drives start to show bad sectors, it's a black hole of unpredictability. Expect problems to return in short order - time to dispose of the disk.
Much appreciated
