Thanks Maxell - tried that previously and could see the drive details i.e. Seagate and model number but it wouldn't register as a drive letter in Windows Explorer or My Computer.
HOWEVER, a little flash of inspiration
Partition Magic!! PM saw the drive, allowed selection and FORMATTING !! Sorted! ... well, as much sorted as anything is in Windows.
Anyway, thanks to all of you for the suggestions .... 'til the next problem
