New SATA hard drive detected in BIOS but not in win 7

hi,

i'm trying to add two brand new and identical 2TB WD Caviar Green hard drives for additional storage only. my motherboard has 4 SATA ports which i use for

- C: / D: 1TB primary boot hard drive divided in two partitions (works)
- E: DVD drive (works)
- F: new storage only 2TB hard drive (works)
- new storage only 2TB hard drive (detected in BIOS but will not show up in windows 7)

what confuses me is that both hard drives are identical and i did not have any problems installing and formatting the first one at all. i obviously connected the second one correctly as well since it's showing up in BIOS, but windows just will not detect it. it's not showing up in Disc Management, i also tried scanning for hardware updates in Device Manager -> Disc Drives which also failed, and a thrid party partitioning program (EASEUS) won't recognize it either.

any ideas?

thanks in advance
