#1 Weird hard drive issues by Harshparker 20.10.2018 23:17

I have 8 drives in a media server, running stablebit drivepool and scanner. all 4TB Seagate NAS drives on a SLI 9207-8i. (migrated from a M1015 HBA card).

started having some weird issues with some of them.

I was getting bad sector readings on 1 drive. copied stuff off it. I ran seatools, all passed except for long generic. I said I will try chkdsk too and get some logs for RMA. I first did a diskpart clean. Stablebit scanner showed bad sectors again, but then seatools and chkdsk all passed. WTF! then another hdd did something similar, unused new sitting around for 2 years put on the same port...exact same. bad at first then ok again.

I replaced both with some HGST 4TB I had lying around. they run about 5C hotter though. I started copying stuff back and one of them disappeared. came back after a reboot and showed damage. same thing, diskpart clean, format...all good again.

what the heck is going on? card and HBA was replaced. only other thing I ran into is maybe a PSU going bad...but would it cause bad sectors to appear, but then later disappear?

I had RMA ready for 3 drives, but they said talk to tier 2 first (on Monday). I said I already lost about 200GB of data as multiple drives going bad at same time not giving me time to recover raid images. don't know if I trust the remaining Seagate drives. all warranties expire in January.

@Harshparker:
Welcome to the Win-RAID Forum!

The fact, that
a) more than 1 HDD was affected and
b) the Seatools detected bad sectors only temporarily,
lets me think, that the HDDs themselves are not the reason for your data loss.
You should try to find out the real cause of your issues by checking other hardware components (like PSU) and the software you are using.

P.S.: I have moved your contribution into the "Off Topic" section, because it seems to have nothing to do with the in-use storage drivers (you didn't even mention them).
