Just purchased 2 of these 2TB internal SATA drives. Moved a whole bunch of stuff onto one of the drives, checked it out as working, and put it up.
Now the drive is seen by Disk Utility as a 2.2 TB drive (instead of 2 TB), and shows as unformatted.
And, of course, there’s some info on the drive that doesn’t exist anywhere else any more.
Any ideas are welcome.
