How Do I switch off TCQ on my Raptor Drive?

[Domo]

Been getting problems with my system freezing and errors sent to the system error log. Many sources have said to disable TCQ but where's this located?

I've checked the drive's properties in device manager but can't find anything remotely like it

3800 X2
A8N-SLI Premium
2 x 512 Corsair XL
7800 GT
74 GB Raptor

Found it. For those that come across this:

Device Manager > IDE ATA/ATAPI controllers > NVIDIA nForce4 Serial ATA Controller > Properties > Primary/Secondary Channel - Uncheck Enable Command Queuing

Thats the one gets rid of error 51 (i think thats the number)
