June 23, 20197 yr I was copying some files to Disk4 of my array, when the PC froze from a kernel panic. After rebooting the PC, Disk4 shows "Device is disabled, contents emulated." The array is also stopped with an "unclean shutdown detected." Starting requires a parity-check. An extended SMART test on Disk4 came back with no errors. How should I proceed?

June 24, 20197 yr Community Expert Diagnostics from your very old version of Unraid are more trouble to work with. Upgrade when you get stable again. SMART for all disks looks OK. Since you rebooted syslog can't tell us what caused the disable. Check all connections. You can rebuild to a spare if you have one, or rebuild to the same disk. Rebuilding to a spare lets you keep the original as a backup, but of course it requires you to have a spare. https://wiki.unraid.net/index.php/Troubleshooting#What_do_I_do_if_I_get_a_red_X_next_to_a_hard_disk.3F
June 24, 20197 yr Author I couldn't get the syslog because I lost net access to the PC and the keyboard was unresponsive. I'm going to try a rebuild to the same disk since I don't have any spare PATA drives, but can I rebuild safely with a "unclean shutdown" warning?
June 24, 20197 yr Community Expert You can cancel the parity check you get from the unclean shutdown. With a disabled data disk it can't really check parity anyway and would just perform a read check. Be sure to check all connections though.
June 25, 20197 yr Author Rebuild to the same disk was successful. A parity check afterward also came back with no errors. Thanks trurl for all the help.
