I got a 1tb sata drive. when I go into my BIOS, it's nowhere to be found, but when i boot up windows and go to my device manager, it's there. now it's not showing up in the list of drives available in 'my computer', nor does it show up in disk management.
One thing i do have to say is that I got the drive set up as 'raid' because when i choose sata, it'll say no sata ports are detected.
New drives are all SATA-II, but many have jumpers on the back that will let them run in SATA-I mode for older mainboards. If you are using the same system, just a different windows, then your problem is probably driver related.
It does matter, as the RAID bios may be blocking it if it has not been configured. It also matters because RAID often requires a different driver than the onboard drives, even if it is onboard (AKA FAKE) RAID.
sweet i got it working! i plugged my drive into a different sata port, and in the bios i set it to sata instead of raid and it worked although when i booted it up i had to format it, losing 15gigs worth of files.
