Okay i dont get it? What is the letter as they are seen under SATA and under IDE. I see a bunch of letters but none of it makes sense. C: C: G

:
What does all that mean? Go this way.
SATA
C: System Drive
E:\ First partition SATA Drive
IDE drive 1
G:
IDE Drive 2
H:
I:
J:
Soemthing like that and tehn go the same route with the IDE Drive. That way we can figure out what is going on.
The way to change them is right click on My Computer>Manage>Disk Management. In there right click on any partition and change drive letter. But you will not be able to change the system drive that you are currently working under.
