Hi Just in case others fall into the trap I just climbed out of! I recently bought a Corsair Performance 256Gb SSD and thought I would install it as boot device for a performance shot. I also purchased a very nice Crucial kit to help the installation. It came with everything 5.25" mount, 3.5" mount, inner case, leads even a soft carry case. The Crucial part number is CTSK01. Now the kit is fine in most ways eg for use as a USB external drive etc. but when I tried to install it inside my case it would only work for data. Everytime I tried to boot form it to install Windows7(32 and 64bit) it would crash so far into the installation. In the end I resolved to RMA the drive back to Corsair and contacted them for an RMA number. However I thought I would give it one last try and removed it from the Crucial kit and plugged it directly into the motherboard via a SATA cable. Suddenly the problems were gone. Obviously there was some sort of conflict between the SSD chips and the chips in the Crucial kit.
