31.50 KiB partition on Apple hard drives

[yawnmoth]

Every Apple hard drive I look at, it seems, has a 31.50 KiB
partition. Any ideas as to what it's purpose is?

More context might be helpful. The hard drive on my MacBook Pro doesn't
have any such partition.

If you are looking at the partitions on an Apple Partition Map drive, a
partition that small might be either the partition map itself (which is
in a partition starting at logical block 1, after the driver descriptor
map in block 0) or the drivers for Mac OS 9.

I suspect it is the former. If you add one block, you will end up with
exactly 32 KB, which is a nice round number. I'd expect the Mac OS 9
driver partition to be somewhat bigger.

I've been looking at the drives in Ubuntu. A friend of mine asked me
if I could see if I could recover some data from a hard drive of
theirs and so, in one of my attempts, I loaded it into Ubuntu to take
a look at it.

Anyway, I think you might be right about it being a partition map - if
you try to delete that particular partition in Ubuntu, you'll get a
"Partition map has no partition map entry!". (after recovering the
data, I figured I'd reformat the drive so it could maybe be used
again).

Thanks!
