In the past when I tried to install Virtualbox and get USB
working I had problems. But you say the other USB drives
are working fine (with Virtualbox). Therefore the chance that
Virtualbox is the problem is small.
Is this a dual file system drive or is it all a NTFS partition?
If it all NTFS you might try 'ntfsfix' to clean it (think fsck).
That may solve your problem.
You also said gparted failed to see it. Is it that it does not
see the partition at all?
How about other systems? Do they see it?
