The cluster size seems to be tagged at the start of the root FAT or sth

I made a backup image in my /home dir (in 4 chunks, first dd barfed on a bad
sector and then I hit a 2GB-1 limit twice),  and cfdisk fixed it 100% by
writing a new partition table.

Thanks muchly Gary and John :)  Now I'll go and make a full backup before
trying again. I think I'll make the partitions with cfdisk this time.
