I tried to use a 40 pin ribbon cable on an Ultra ATA133 controller and drive. Windows2K loaded, but then declared files were corrupted and was never able to boot again.
I knew that the 40 pin cable would not allow the drive/controller to work at full speed, but I thought it would just slow down to ATA speed. I just did not have a 2-port 80-pin cable available and thought the 40 pin cable would work for the short time I needed to connect this drive.
Did I do something totally wrong or was I just the victim of a cable that might have been slightly faulty or a connector that was not fully inserted? Has anyone else done this and what were your results? Can anyone point me to an industry reference that says this is a no-no and what the consequences are?
I will award points only to answers based on real experience or references to an industry standard not to guesses.
