June 1, 20251 yr Hi,Woke up to a notification that one of my drives (sdb) is showing errors, currently 9600. When I checked I also notice that the parity check was often dropping to less than 2.5 MB/s for long stretches of time (~15 mins) before returning to normal speed for a few minutes and the cycle repeating.SMART report for the drive seems fine to my untrained eyes but this is the first time I've had errors showingon a drive.Just curious if I should let parity run it's course, despite an estimated finish of over 2 months, or if I should stop the check and replace the drive ASAP.Diagnostics attached.Thanks thepitt-diagnostics-20250601-0818.zip
June 1, 20251 yr Author After swapping the cables I am still seeing the same issue.Additionally I ran a DiskSpeed test before an after the swap and the results are similar (attached). There is a catastrophic drop in speed around the 750GB mark on both the old and new cable.I assume based on these results I should be replacing the drive ASAP?I probably should not resume the scheduled parity check until after the swap as well?
