Hello...I spent the whole of today...12pm - 22:45pm researching on the internet on how to get this drive working. It's a DiamondMax Plus10 250GB SATA drive. System spec. barton 2800xp 512mb ddr powercolor radeon 9800pro Asus A7N8X Deluxe 2 IDE HDD's already installed 2 CD ROMS 1xDVD/CDRW 1xCD Windows 2000 professional So the SATA is onboard but wouldn't show up in BIOS as anything. I installed the Silicon drivers from the website and changed the SATA jumpers on the board and windows booted up found a new...thing (didn't see exactly what) and installed it fine. It shows up in device manager under SCSI and RAID controllers > Silicon Image SiL 3112 SATARaid Controller. When you double click it says "This device is working properly." in the grey box. But it doesn't show up in "My Computer" or a program i downloaded "DiscWizard" OR in "Disc Managment". I updated BIOS and it now shows something about boot sequence for SATA and SCSI. So i put it as boot from SATA then SCSI (rather than SCSI then SATA). That was the only updated thing i could see. Still not showing up in "My Computer". Although while booting up the computer, after it's detected all the IDE optical devices and checked the RAM etc. it comes up with something about launching the SATARaid Utility, if you leave it it continues to boot, if you click "F4" as it asks it does a check then says there's no device or something then "disables" it. SO WHY CAN'T I USE MY HARDDRIVE? Thanks in advance Raab.
