The drive originally got recognized as /dev/sdb, and mounted with its 
label as /media/OneTouch. After the power outage, VMware had unwritten 
I/O waiting for the drive, and the drive instead got loaded as /dev/sdc 
and mounted as /media/OneTouch1.

By the time I'm able to mount the drive, it's already past the point 
where it's decided the drive is /dev/sdc and not /dev/sdb. I was hoping 
there was some way to make it recognize that the drive is the same 
/dev/sdb it's waiting for, when I power up the drive.
