I got an extra disk drive for my Game Doctor SF7 but it didn't respond when I put a disk in. It was getting power. I noticed its data connector didn't have many of the pins on the lower row even present. On the drive that worked, they were present and almost all grounded. Turns out the GDSF7 relies on this to detect that a drive is connected. The fix is to connect two particular pins on the connector together. Looking at the back of the female ribbon connector that goes to the drive, bend a short piece of wire into a U shape and stick it into the 5th and 6th pins from the left on the bottom row:
It doesn't matter that it sticks out a bit, since it will be where there are no pins on the drive.
The male connector on the drive that required this fix looks like this:
Code:
. . . . . . . . . . . . . . . . .
. . . . ._. . . . . . . . . . . .
1 2 3 4 5 6 7 8 ... 17
