I did as I was told, and THAT problem was solved. But then came a new one. I tried to use it on the same cable where the DVD drive is connected. I connected the end point to the HDD, and the middle one to DVD Drive. Then neither worked. I mean, neither showed up in My Computer. If any one alone is connected, that will work. What to do?[/QUOTE]
Also remember to use 80-pin ribbon cable not 40-pin and also make sure the dvd IDE drive has either MS isn’t jumpered so the computer will see that as the only one and make it Master otherwise if there are two devices on the cable one has to be jumpered to MS and the other to SL to make the configuration work. The second part would solve your connection problem.
Here’s a wiki description:
Multiple devices on a cable
If two devices attach to a single cable, one must be designated as device 0 (commonly referred to as master) and the other as device 1 (slave). This distinction is necessary to allow both drives to share the cable without conflict. The master drive is the drive that usually appears “first” to the computer’s BIOS and/or operating system. On old BIOSes (Intel 486 era and older), the drives are often referred to by the BIOS as “C” for the master and “D” for the slave following the way DOS would refer to the active primary partitions on each.
The mode that a drive must use is often set by a jumper setting on the drive itself, which must be manually set to master or slave. If there is a single device on a cable, it should be configured as master. However, some hard drives have a special setting called single for this configuration (Western Digital, in particular). Also, depending on the hardware and software available, a single drive on a cable can work reliably even though configured as the slave drive (this configuration is most often seen when a CD ROM has a channel to itself).
