I've been having trouble with a Zbot/Heur virus and am currently problem solving it with the malware team here on this site. Due to this virus I have used MBRCheck to scan my hard drive's MBR's and it comes up with the following for my external drive, a 500Gb Maxtor One Touch 4: [465 GB \\.\PhysicalDrive2 RE: Unknown MBR code SHA1: CEECB0630DEB98A912C967BD5561D0F2BFE7D8C6 ] which lead me to believe I had a rootkit on my external drive. It is possible that the bundled backup software is what is causing this but I have decided I want to be rid of whatever it is on there.
My problem is that I am unable to find a command or program to erase the MBR on this external drive. I have tried many things and am aware of fdisk /mbr but that won't work as the disk is not in track0 and windows recovery console runs before USB is detected. Boo. The closest I have come to being able to format it was using testdisk-6.11.3 in that I can get this program to read the MBR but it comes up with an access denied error if I try to overwrite the MBR.
Anyone got any ideas I could try? I really want to do this so I know I can trust my backup drive but can find no solution.
