Linux's software raid won't be compatible, *however*, there is a (free,
opensource) utility that emulates what the hardware RAID cards do, in order to
access the data from Linux. This might help your friend considerably.
Catch is, I can't remember the name of it.
However, if the data is hard to retrieve from backup, then it's probably worth
your friend crawling through Google results to try and find it.
