Neither OS supports software RAID 5. Why would you expect an unsupported
option from one OS to work in another OS? There may be a hack for Vista but
it will obviously be different and again you would be in an unsupported
position. It may break without any notice because of updates or service
packs. Software RAID 5 is not a good choice for any OS. Hardware RAID
controllers are quite inexpensive and fully supported.

Hi all!
I'm using a software RAID-5 hack in WinXP as described by Tom's
Hardware(1), but when I boot in Vista, this RAID array is just
"failed". The XP hack is RAID-5 such as it also exists in Windows
Server and Windows NT.
Are XP & Vista RAID really incompatible?
Naturally I don't want to "just try it" at the risk of essentially
formatting my 950GB array.
