I have upgraded from Windows XP Service Pack 3 to Vista Home Premium
on a Toshiba Qosmio G35-AVA600 which has two 80GB SATA hard drives
configured as RAID-0. 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 canít
format it from disk management services because it is not shown.
The weird thing is that I am not missing any files, but perhaps I had
not used any space on the second hard drive, therefore I wouldnít 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 the
second hard drive WAS listed in the BIOS.
Iíve read the many threads on second SATA hard drives but no one
mentions that their BIOS does not recognize the drive as well as
How do I fix this problem?? Any help at all would be greatly
