January 8, 20233 yr The SMART shows OK, and the last parity check (7 days ago) showed OK, but now the drive is showing READ errors and is disabled. About a month ago, I noticed the same issue, and I removed and then re-aded the partity drive and it added/rebuilt fine, but now I'm back to this again. Is this a bad disk? Something else goin on? Hopefully someone smarter than me can see something in the logs. Thanks for any help. mediaserver-diagnostics-20230108-0806.zip
January 9, 20233 yr Community Expert Disk dropped offline so there's no SMART report but this is usually a power/connection problem, post new diags after a power cycle.
January 9, 20233 yr Author By a power/connection issue, do you think it could be power supply issue? Bad cable? loose cable? I'll open up the box and reseat all the power connectors, and then re-run a diag and post it here. Thanks, Sean.
January 9, 20233 yr Author I adjusted all the sata cables and power cables and rebooted. here's the new log. The drive is still disabled. Does that mean that the system thinks it is physically not there? mediaserver-diagnostics-20230109-1736.zip Thanks

SMART report for the disk is in the diagnostics, so it was there when diagnostics were taken. 14 minutes ago, itimpi said: stays disabled until the drive is rebuilt.

January 10, 20233 yr Author Thanks I'll rebuild. This is the second time in 2 months that I'll be rebuilding the parity drive. Wish I fully understood why this was happening Thanks for help. Much appreciated.
January 10, 20233 yr Community Expert Solution Check connections, SATA and power, both ends, including splitters. Don't put more than 4 disks on a single power cable. Don't bundle data cables. Make sure all cables have enough slack so they can sit squarely on the connection without any tension. Try a different cable if the same one keeps causing problems.
