Synology Clear Drive Error

Description

Clear critical drive errors so DSM will let you use the drive

If DSM decides a drive is critical DSM stores "status critical" in a database and will not let you use the drive again. If you run an extended S.M.A.R.T. test on the drive in a computer and it says there is nothing wrong with the drive DSM will still refuse to let you use the drive. You can use this script on the Synology to delete that drive's "status critical" entries from DSM's database. Then DSM will let you use the drive again.

NOTE The script does not fix a faulty drive.
