Disks that get spun down eventually accrue errors at the same rate of every other spun down disk. Errors do not persist after a reboot. Disks show in unassigned devices by itself. They are manually removed after each reboot. This has happened 3 times now.

Spun down drives with same amount of errors.

Array drives appearing in Unassigned Disks.

Syslog shows bad sectors but attributes show large amount of seek errors which also do make sense to me since the drives only accrue these errors while they are spun down.

Thanks for the help. This is my first time asking for assistance so if more information is needed please let me know. Thank you.

All the disks are dropping offline. My first recommendation would be to update the LSI firmware; if that doesn't help, see if there are any issues with spin-down disabled.

Much appreciated. This is a rebuild that is using "new to me" hardware. An Avago 9305-16e that I flashed to IT Mode myself. It's weird cause it has been about 3 months since that rebuild and only now has this error issue appeared. I will double check that I have the latest LSI firmware but in the meantime will monitor with Spin Down disabled.

Thank you
