There's the BIOS, Device Manager, Disk Manager, Explorer.
You didn't reveal which area it's missing so my guess is the drive is blank and you need to prepare it in drive management.
Hello. I built a new computer to run the Win 7 OS. The new computer has an Intel i5 CPU, an ASUS mobo, and two separate Seagate HDs.
When I first started the new computer, the BIOS recognized the two HDs. When I installed Win 7 on the computer, the install program asked which HD (recognized as disc 0 and disc 1) the OS should be installed on (I choose disc 0).
The OS is now up and running, but Win only recognizes one of the two HDs in the computer.
What do I need to do to get Win 7 to recognize both HDs? Thanks
