USB drive turned GPT protected after power outage

[dslabbekoorn]

I had a massive power outage & surge here due to a storm and when the server came back up the 3TB drive in a USB enclosure (Sabrent) showed as GPT Protected Partition and alot of un-allocated  space.  Unable to access or be seen by Drivepool or windows & you can't touch it.  Putting it back into the malfunctioning enclosure & it works fine and is seen by all.  Only problem is the drive runs full tilt all the time and overheats (passive cooling in the "working" enclosure)  How do I go about removing the drive from the pool and then making it usable in the new enclosure to re-partition and reformat?  The drive is locked (GPT protected partition) by any other method of connecting it to the computer.  Just don't want to lose 2+ TB of data or my hard drive.  Any help would be appreciated.  Thanks.

Went for it & it worked.  Put the drive back in the bad enclosure & sure enough there it was on restart.  Let Drivepool settle down then removed the drive from the pool with duplication later.  Took 2.5 hours to remove a 3TB drive.  Powered down put it in the new enclosure (with fan) & used Mini tool Partition Wizard free to re-partition & reformat. Added it back to Drivepool & its balancing away.  I'm out one cheap enclosure & not a $100 drive or 2.5TB of data.  No short way around I could see, took most of a Saturday afternoon while I watched my college team get pummeled.  But that's another story.  Hope this helps out someone who swaps USB enclosures or moves a drive to internal get out of jam & get their data back.  Found an old post where Christopher made a suggestion to a poor soul with the same problem as me, worked both times, so thanks Chris for helping without even seeing this post.

Unfortunately, some enclosures do this.  Fortunately, it's not very common, but it sucks when you find one that does.
