Based on advice received in the Malware forum, which was corroborated elsewhere, I have run DBAN to get rid of a bad virus (RAMNIT.AS) on my Dell XPS 8500 that is able to infect Master Boot Record, hence the ned to wipe everything including Dell's System Restore Partition Upon reinstalling Windows from a reinstallation DVD I am finding that the hard disk, which is supposed to be 1TB, only shows 931GB. I think that the missing 69GB is about the size that the recovery partition would have had. DBAN should have overwritten the whole disk, including the recovery partition. Certainly I can no longer see the usual options when attempting to boot with F8 so I think it must be gone, but I am just wondering: 1) can I be sure that the recovery partition (and virus) are really gone, and 2) does anyone know what might have happened to my 69GB and whether there is any way to get it back? Thanks!
