My Win 7 HDD contains the automatic Windows 7 install with 2 partitions, System Reserved and a "C" partition.
After reading the thread (great stuff
), I have a couple of questions about the "clean" and "clean all" commands:
- Does the "clean" command accomplish the same thing as deleting both partitions from the Disk Management Console, with the addition of deleting the MBR when using the "clean" command? I'm guessing that partition-deletes from the Console won't delete the MBR since it's located prior to the beginning of the first partition, the System Reserved partition.
- Does the "clean all" command unhide and overwrite any "Host Protected Area" sectors, more known as the HPA? Those are typically located after the last user partition on a HDD, for those HDD's the contain a HPA.
After reading some articles about HPA's, it would appear that one would need to "unhide" the HPA before most disk-wipe tools can access that area to overwrite any data located within the HPA.
Seatools (Dos) and "HDDErase" will unhide the HPA but "DBAN" doesn't access that area according to the DBAN's site FAQ section.
I think there is a Linux command that will unhide the HPA but I don't recall that command at present.
