There have been broken 3ware firmwares in the past that specifically
effected RAID5. A quick test of the same hardware under LINUX or win2k
would confirm if this is another firmware issue or driver specific. Another
common issue across all platforms (i.e. firmware issue) was changing the
disk stripe to anything other than the default 64k on RAID0 or 10.  This
too would break things on all operating systems.
