Overview: I use a backup storage enclosure with 6 backup drives incrementally backup up and taken off-site. One day I noticed that the backup process was failing. I logged onto the server that is connected to the drives. I then noticed that none of the backup drives were currently mapped when the next one numerically should have been.
At first I chalked it up to a simple mistake of not mapping the drive previously. However, when I had attempted to map the drive BAK6 I received an error of: "parameter incorrect". BAK6 also had a specific flag of "active" in it's Status" where all the others are simply "Primary Partition".
I was able to map the other drives fine so I mapped BAK1 to E. When I removed and re-added the drive physically it auto mapped E to BAK6 unmapping it from BAK1. Then, BAK1 could not be mapped giving the same error. I ended up restarting the server and things started working again but now BAK6 is still marked as active.
Question: How do I remove this flag of active from the drive?
