Hi all. So I have a DIY NAS running. For month it was having issues with disk failing (two in particular) and having to rebuild party, one disk would also switch from 6GBPS to 1/3GBPS randomly.
I first thought it was an issue with the HBA card, then an issue with the disks, but I swapped out the PSU and I have been running smoothly, and more quickly, ever since. Its been so nice, previously, the server felt like I was walking on egg shells, and I didn't know why for a long time.
What led me to replacing the PSU was the strange start stopping sound I noticed one day coming from the server, and then checking the attributes on the disk.
All my disks give a PASSED on their SMART, but... two of my disks have a power cycle count of, and it pains me to say: 3300 and 880....
Of course, these are the two disks that I was having to rebuild. I still don't quite know what the PSU was doing that made this happen.
The two disks in Scrutiny are reporting as FAILED because of a high Command Time-out, but I would imagine this wouldn't be happening anymore now that the issue is resolved?
I guess my question is where should I go from here? Are these drives seriously in trouble?
