SSD drive dissappears when I boot up to Windows 7

[TC Basset]

I'm running main HDD in RAID and all is ok there. I check in BIOS the SSD is recognised - using the Control+I command I can see the SSD is available and status is normal.

I boot to Windows 7 and it disappears.

I'm running a 550w PSU and wondering if it's a power issue, but why is it not a power issue in DOS?
It's puzzling as I previously had it working before until I recently reinstalled Windows 7.

BTW, I did edit my Regedit before this so I could change from IDE to RAID on my main HDD.
I changed
iastorV Start = 0 (THIS IS WINDOWS RAID, HAVE IT ON 0 SINCE 0 MEANS ON)
pciide = 3 (THIS IS IDE, HAVE IT ON 3 SINCE 3 MEANS OFF)

Before I did this it would get BSOD when starting Windows having only the BIOS changed to RAID on main HDD.

Should I have changed the pcide to 3, and instead left it at 0 ?

Anyone have any ideas?

This has been sorted - I removed the Kingston SSD and used an OCZ Agility 3 SSD which was instantly recognized. Apparently Sandforce, the controller the Kingston uses has a problem so that's what it was.
