This is not entirely correct - Let's think back... Even tho a drive is specked for 36 gig, rarely is it ever the full 36 gig. Diff companys use diff figures as to what a meg is. For example, IBM (iirc) uses 1000 k for a meg while others use 1.4 etc. Drives when formatted are never as large as they claim to be. -- Best regards, Chris Important letters which contain no errors will develop errors in the mail.
