I thought so too, but lately got into trouble with some Olivetti M24 pc's ... a [Stoned] infection immediately resulted in some subdirs full of illegal file entries, lost clusters, and crosslinks. The same thing happened again within a day after low-level formatting the system, when another user didn't think it necessary to check his disk or even removing it while rebooting. So I'm pretty sure it's the Stoned infection that's causing the FAT and/or DIR problems, it may be because of a non-standard FDISK that comes with Olivetti's MS-DOS 3.2. Anyhow, it helps to have a backup :-) Jan van 't Ent, Apparatuurbeheer (microcomputer support & maint dept) ERASMUS VANTENT@HROEUR5.bitnet UNIVERSITEIT telefoon +31 10 4081337 jvte@cs.eur.nl usenet ROTTERDAM telefax +31 10 4081372
