BIOS AND Vista Not Recognizing 2nd SATA Hard Drive

By ejames6342 ·
I have upgraded from Windows XP Service Pack 3 to Vista on a Toshiba Qosmio G35-AVA600 which has two 80GB SATA hard drives. In Windows XP the drive was seen as one 160GB hard drive. No problem.

After I installed Vista the second drive is not showing and I can't format it from disk management services because it is not shown.

The wierd thing is that I am not missing any files, but perhaps I had not used any space on the second hard drive, therefore I wouldn't be missing any files.

Also, after installing Vista I checked the BIOS and it does not see my second hard drive, nor does My Computer but it is there as I have made no hardware changes. All I did was upgrade from Windows XP Service Pack 3 to installing Windows Vista. I have the latest RAID drivers from Toshiba which was updated after I installed Vista. The latest BIOS was installed from Toshiba website BEFORE I upgraded and it WAS listed in the BIOS.

I've read the many threads on second ATA hard drives but no one mentions that their BIOS does not recognize the drive as well as Vista.

How do I fix this problem?? Any help at all would be greatly appreciated!!

Yes, I have Service Pack 1 installed. Also, after installing Vista I went to Windows Updates and downloaded all the updates available at that time.

I honestly don't know if the SATA controller is the culprit here, and my own experience with Vista is limited. Hopefully another TR participant will joint this thread soon and help you resolve this glitch.

SATA controller

by ejames6342 In reply to See OH Smeg's post of 7 J ...

I would think that if it was the SATA controller I wouldn't be able to see the main C hard drive that I do see and I have never had any problems with the controller.

Am I on course here are am I way off?!?

Any help would be appreciated.
