Hi, bought new comp a few months ago with 2x @



Disk 1: Primary
Partion 1: 230GB (Windows)
Partion 2: 700GB (Storage)

Disk 2
Partion 1: 930GB (Used: 925GB)

Today when I fired up the computer, when bios was loading.. I noticed it took 2-3 sec to find Disk 1, it took 30 sec searching for Disk 2.. then it skipped disk 2 and went to loading Windows, only 1 HDD in windows

So the problem @ Disk 2 cannot be found in Bios neither in Windows as a result

The things I've done
Changed Disk One's Power & SATA cable to Disk 2.. It starts fine, feeling and hearing it as it should, so no mechanical error, and it looks like it was when i bought it so no exterior damage at all, and the green thingy under it with the circuits looks fine also.

Help, please!
