Hi Matt,

Firstly, make sure that the FAT partition on hd0 is mounted somewhere and that
the FAT partition in hd1 isn't

then as root run the following command (asuming  hd1 is primary disk on 2nd
controller and that you used primary partitions)

dd if=/dev/hdc1 of=/<mnt>/hdc1.img bs-1024 count=<numblocks>

where

<mnt> is the mount point of the FAT partition on hd0
<numblocks) is the number of blocks you wish to copy.

Fixing the partition depends on what state PM left it in.  You could try using
the linux version of fdisk to delete/recreate the partition table in both the
16k and 32k cluster sizes until you get something that works.

Chances are though, that if it was half way throught the conversion - you're
stuffed.
