DT is this fancy Disk Test command from Norton. It is supposed to, among other things, add bad blocks to the FAT (what's that stand for?) with the /d command. If true, does it handle multiple partitions? Stuart

The usage of DT is (from the version 4.0 manual): DT [d:][filespec][switches] Switches: /B Perform both disk and file test /Cn Mark cluster n as bad /Cn- Mark cluster n as good /D Test the entire disk for damage (i.e., not just files) /F Test all files on the disk for damage (i.e., only used clusters) /LOG Format output message to be suitable for printing or logging to a file /M Move questionable clusters to a safe location, and mark them as bad /S Test files in subdirectories also (only meaningful when a filespec is given). With no switches, DT just examines and reports. >If true, does it handle multiple partitions? > > Stuart As indicated above, giving a disk name will cause DT to examine that disk. Normally, it default to the current disk. So, C> dt will examine the current disk (C: in this case), and, C> dt d: will examine drive D:. marc =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= = Marc Johnson BITNET: rna!marc@rockvax.bitnet = = Rockefeller Univ.

No, not across partitions because each partition (assuming all DOS) will have it's own FAT. To clean house with DT supply the drive letter. (obvious hint try C>DT ?)
