how would I do that before I install windows onto the drive? would I just plug the drive into the computer and download the firmware then just put it on the SSD and run it?
Yes, connect the SSD to an available port. Download and install the OCZ Toolbox to your 750GB HDD. Run the Toolbox and check which version firmware you have on your SSD. If it's lower than 2.22 then update the SSD.
