I'm trying to zero out hard drive and start with fresh install. However when trying to create a new MBR with fujitsu zero out program provided by oem it fails and says disk error. I tried fixmbr and fixboot but problem still persists with saying MBR is non standard or corrupted. I suppose that since FDISR was so deeply entrenched into the MBR that it's what is causing my inability to zero out the mbr and so my question is what is a good program that will zero out and do a low level format/wipe of hard drive? OEM product didn't work. Is there a MBR rebuild or wipe program that will get rid of ENTIRE MBR and BOOT record?
