2nd Drive not recognized after switching from IDE to AHCI and back again.

I decided to change from IDE to AHCI (using both: Bios and RegEdit).

System was really slow to boot, so I switched it back to IDE again,

But now my problem is that I still have the incredibly slow boot up and now my 2nd hard drive is not being recognized (even in Disk Management its not recognized)

I would appreciate any help. 
I want to avoid re-installing windows.

is there any way to remove all the AHCI drivers and also to get my 2nd drive recognized again ?

Thank you  

Windows 7
Gigabyte Motherboard: GA-X58A-UD3R (Ver. 2)
CPU: i7 950
Graphics: PALIT GeForce GTX-470
Memory: 12GB Kingston Hyper-X KHX1600C9D3K2/4GX (DDR3) 
........... (All banks are full with identical RAM)
Hard Drives:
1GB WD (blue) for the OS
2GB WD (black) for storage (not recognized)

These are the Values I used in the RegEdit:

For IDE mode:
msahci's START value is "3"
pciide's START value is "0"
For AHCI mode:
msahci's START value is "0"
pciide's START value is "3"
