Hello Scott
first off you should not be running 64bit Windows ATI drivers / when you are using a 32bit Windows XP operating system ?
I would try uninstalling the drivers you have thru the add remove / programs found in the control panel / then download and install the correct windows xp 32 bit drivers for your video card
next you need to go to your motherboards webpage / then downloads / then look for your motherboard model number / download and install the chipset drivers ( thats an
.inf package) for your motherboard
BTW: you will NEVER see 150mbs transfer rates "no matter what you do!!) thats a purely
BULL crap number >>>>> the best transfer rate you will see out of an internal sata drive / stand alone = 70 something mb/s
raid is combining two or more drives to act as one / such a set-up will be faster than the 70 something rate but not any single solo drive >>>> hell; I have spent a small fortune on the fastest of single SCSI drives and best of SCSI controllers to get 80mb/s transfer capability from a standalone hard drive....... therefore you can FORGET about that fictious 150 mb/s number >>>>>>>
let us know if you need assistance with these tasks
best regards
joe
