What Win32 IOCTLs are involved in fully initializing a hard drive? I
am referring to a hard drive that has been subject to a full
declassify / erase operation.

IOCTL_DISK_DELETE_DRIVE_LAYOUT says "the disk will be formatted from
sector zero to the end of the disk" but of course without any
partitions format has no information to work with.

IOCTL_DISK_CREATE_DISK appears to be the correct follow-up IOCTL to
IOCTL_DISK_DELETE_DRIVE_LAYOUT but says nothing about formatting.

IOCTL_DISK_SET_DRIVE_LAYOUT_EX may or may not be superfluous if you
use IOCTL_DISK_CREATE_DISK.

IOCTL_DISK_FORMAT_TRACKS and IOCTL_DISK_FORMAT_TRACKS_EX says floppy
only.

IOCTL_DISK_FORMAT_MEDIA and IOCTL_DISK_FORMAT_VOLUME says Windows CE
only.

Would be nice to see the source to DISKPART.EXE or something
equivalent. Thanks.

Do you have the document 'fatgen103.docx'? If not, get it and understand
the layout of the hard drive. True, it is just for FAT12/16/32, but it
covers the MBR (Master Boot Record including the partition table) and PBR
(Partition Boot Record). I just write to sector zero with a valid MBR and
that is easy as soon as you compute the correct values for the partition
table.

No. But was able to find fatget103.doc on the web. I'm afraid it's
much lower level than I want to work with. Would like to keep within
CreateFile/DeviceIoControl/CloseHandle. Thanks.
