I have a RAID 0 array (2x300GB WD Velociraptors connected via SATA) which appears to have crashed. Both disks show up in the BIOS, but the RAID volume is not listed at bootup by the RAID controller message.
When I just ran Vista installation (on a different hard drive), it only showed a single of the Velociraptors (showed 279GB space available). After I installed Vista it shows a drive d: with 0 bytes and when I click it asks if I want to format (which I have not done - I have left the drives unaltered since the crash). I don't know if this drive is just one of the drives, or represents the array.
I googled RAID 0 data recovery and found this FAQ, which says:

I googled RAID 0 data recovery and found this FAQ, which says:
How do I create this "block-level copy of every sector on each hard drive"? Can this mirror image be copied onto a separate single hard disk (assuming it has the space), or do I need to create a new RAID 0 array and then copy each of the disks to a new disk?Q: Could data recovery software utilities be used to recover my RAID 0?
A: Perhaps, but it wouldn't be the safest approach. Most data recovery software will require the read / write heads to constantly travel over areas of the original disk that, if there is any physical damage, could render the surfaces useless and beyond recovery. The safest method of recovering data from a failed or corrupted RAID 0 volume (or with any storage device) is to create a block-level copy of every sector on each hard drive. The copied image is then used to reconstruct the original volume and rescue the required files and directories. This approach, while more time consuming, maintains and preserves the data integrity of the drive media and limits the number of times that the original drive needs to be accessed. It also protects against any writing to the original media, which could result in an inadvertent overwrite of the data that needs to be recovered.
