Comment (by pulkomandy):
To be clear: normally this should not be needed. Creating a new partition
table with DriveSetup should be enough.
I'm aware of two possible problems:
1) On a disk previously formatted as GPT, the old GPT data may not be
erased when writing an MBR. The BIOS (or Haiku itself) may then try to use
the old GPT instead of the new MBR.
2) On a disk previously formatted as BFS, there could be confusion about
the block size. Basically, the BFS driver will set it to the filesystem
block size (usually 2K), but the MBR driver expects it to be set to the
physical sector size (usually 512 bytes).
The right thing to do is solve these two issues, to make sure the
partition layout is created properly. No need to clutter the UI with
workaround and hacks, which would make things even more error prone and
confusing.
