The choice of reformat-current-config or reformat-new-config is made by a switch on the back of the drive. It is different for the 9153A, B and C. You need the appropriate owner's manual. I suggest reformatting as a single volume, using the HFS file system. You will lose all existing data when you do this, so be sure to back up what you have. > While we're on the subject of disks, I see that BASIC 5 now supports > a Hierarchical File System.

I think so. Regards, Hewlett-Packard Bob Niland rjn%hpfcrjn@hplabs.HP.COM 3404 East Harmony Road [hplabs|hpu...!hpfcse]!rjn Ft Collins CO 80525-9599
