yup, this has been a nasty nightmare.
running WinME on my Grrrlfriends computer she kept having 'slow downs', BSofD, unexplained shut downs & reboots and the 'freezes'.
She ran ME Second Chance, like, 100 times in a fornight, reformatted, re installed but after a couple of reboots the same thing happened.
all the Anti V software (Norton, PC-Chillin, Mcafe) failed to detect anything, Norton at dos-prompt and Windows.
The problem reached it's peak this weekend when the FAT info dissappeared after every second reboot and I had to restore with fdisk and reinstall ME second chance as microsoft will no longer let you format /s or SYS C: (b---tards) you can only do that under windows or from instillation CD grrrr. and I didn't have my win95 or dos622 disks here.
now the problem got worse, Norton found it had a boot sector virus but claimed that the FAT was completely filled and could not restore or rewrite another (boot sector holds 3 copies I believe~ so fdisk /mbr should be done 3 time to REALLY kill any bad stuff in it!) so....
rebooted from my own EBD with lowlevel progs on it but now the entire FAT has vanished and the drive is completely unreachable. The BIOS detects it okay, as both a master and as secondary slave with all the right geometry but none of the microsoft OS will acknowledge it's existence at all, (I have yet to try it on my Linux system though...)
I have had to buy a new drive and reinstall ME on that but there are some things on the other disk I'd like to preserve if poss but might just have to loose them with a low level format & zero the bugger out.
anyway...long message but does anyone know of a virus that wipes both the FAT and MBR rendering the disk unreachable to anything except Bios & screwdrivers???
I have just had the thought it might be a BIOS virus and I should have cleared the CMOS before putting the new drive in but I can work backwards on that later....
any ideas would be appreciated
Thanx
