Unfortunately, the data will still be on the disk but unless you have
the software/bios/controller that knows the exact format that the data
is stored in, you won't be able to access it. From my readings, when I
was setting up some RAID servers, you have to be very careful with
hardware raid, especially if it's implemented as an onboard bios rather
than true hardware. No two implementations are exactly alike!

For my purposes, I have used the Linux based software raid for a RAID-5
at home and and a RAID-1 at my wife's church and have been quite happy
so far. With these setups, I can take one or two (for the RAID-5) disks
to another machine, boot the correct version of Linux, and bingo, all
data is available.

Of course, implementing RAID does not eliminate the need for other
backups of your data. :-)
