I believe this advice came about because the OS uses the first track/cylinder/block to store various bits and pieces. Early disk partitioners used to allow this area to allocated to user areas, hence there was a possiblity of overwriting this area. Most OS's no longer allow this area to be allocated when the disk is partitioned so you shouldn't have a problem. But if you have any doubt I'd test it. -- Paul Watson # WF Software Ltd # It said run using Windows 95 Tel: +44 1436 674629 # or better in the manual Fax: +44 1436 678693 # so I used Unix www.wfsoftware.co.uk #
