Here is the recommended procedure from Glyph:

Click on the Start Menu

Click Control Panel

Double Click Administrative Tools

Double Click Computer Management

Double Click Disk Management – Usually the Wizard pops up here to assist
you – or hit cancel.

The drive should show up on the right hand side of the screen and is
probably designated Disc 1

Right Click on Disk 1 (small box on the left ) and choose initialize

Right Click on the large box on the right and choose new partition

The wizard will probably pop up again here – choose primary partition

Next choose size – all if only 1 partition

Assign a letter

Choose fat 32 or ntfs (fat 32 will show up in win/98 and on a mac desk top –
ntfs will only work on 2000 and xp**** fat 32 has a 32 Gb limit so if you
are formatting drives over 32 gb you must partition the drive*******

Volume label – name drive

Click all - finish
