Sam's message was a lot more pessimistic than what I actually said in the
meeting.
I did install NT 4 and NT 5 on different partitions, and I installed NT4
first and then NT5 (both using their respective versions of NTFS. The
problem was (apparently) that NT5 upgrades ALL NTFS partitions to NTFS5 on
install (regardless of which partition you actually install NT 5 to), so
the NT4 partition was reconfigured to use NTFS5, and thus cannot read its
own data. I reinstalled, this time installing FAT for the NT4 partition,
but I haven't had a chance to check if it works yet.
