So you could dd 512 bytes of /dev/zero to the drive, or use "wipefs -a
/dev/sdX", then use parted to "mktable gpt" and set up partitions.
That will not work. Parted replaces the PMBR in such a case. So does
gdisk.
wipefs -a after parted or gdisk will cause both PMBR and GPT primary
and backup headers to be invalidated. So to wipe or invalidate the
PMBR has to be done with dd.
OK, so after I partition with parted, I clobber the first 512 byte sector
with zeros, then the drive will retain partitioning info?
GPT partitioning info, yes. If you're using an OS that doesn't know
what GPT is (?) then you have just two options remaining which is BIOS
boot order or the one time boot menu.
Sigh!!!!
Thanx!
