Strange thing happened this weekend.
A friend of mine called and told me her machine wouldn't boot, and she had a message that the hard drive wasn't being found.I tried a new cable and some other troubleshooting, but couldn't get it to recognize that a hard drive existed. I then took the drive, jumpered it as a slave and hooked it into another machine. (I used the cable connector in the middle of the hard drive ribbon cable which was hooked to the CD player). When it tried to boot, it couldn't recognize its master drive! (let alone the slave drive.) I tried cable select with the same result.
I'm puzzled as to why the presence of a slave drive (good or bad) would prevent the machine from finding the master drive.
