SAeems to be something spreading from the governmentto the computer community.... Specifically, on a new HD, fresh install of WinXP Pro, during the initial copying of files to the HD (RAM?), after a bunch of SCCSI drivers, etc., suddenly he message comes up: "The file FASTFAT.SYS is corrupted. Press any key." Which pressing causes a reboot, and comes around to the same message again and again. Hmmmm. The WinXP CDROM looks OK; no scratches, etc. The HD has passed all the Maxtor diag tests perfectly. Any ideas?
