Strange CDROM Detection Problem - Club CDFreaks

falcons_85 · 06-05-2004

Hi there

The other day I went to disconnect my slave CDROM drive from the machine, leaving my burner as the master. When I went to turn the computer on the light on the burner stayed on.

The machine slowed down as the BIOS was having trouble detecting the CDROM, it was not detected. I checked jumper settings and tried another cable but to no avail. I plugged the other cdrom in by itself, disconnecting the burner and it did the same thing.

Here is the strange thing. When both CDROM drives are plugged in they work fine. When one is plugged in as a SLAVE by itself it works fine. When one is plugged in as a MASTER it is not detected and the drvies light stays on for some time.

I'm totally stumped as to how this can happen. Is there any way I can fix this?

Try leaving the cd-rom alone with no jumper.
Also try cable select.

Sometimes strange things happen.

The light staying and failing to detect on usually suggests a cable fault.. often the cable in the wrong way. Check that pin 1 (the red line) is next to the power for both master and slave.

Cable select if you have the right 80strand cable is another choice

Agree with the other posters. If the drive detection goes really slow its either a cable or jumper problem (for instance it will do this if you have 2 drives on master settings on the same cable) or one drive in cable select and one in master or slave (with the master or slave one in the wrong position (like the master at the middle which i beleive is reserved for slave cable select)

Cable select goes

1======2=====3

1 is for motherboard
2 is for slave
3 is for master

CDROM jumpers are pretty standard (USUALLY). say you have :::
usually it goes in this order ( the O is the jumper)
O:: cable select
:O: Slave
::O Master

If it has more pins add them before my diagram so if it has ::::::
it would be
:::O:: CS
::::O: Slave
:::::O Master

Oh and i never recommend putting anything on cable select. Only some compaq machines prefer cable select, but that usually only speeds up the detection, not makes it not recognize them

What's the length of the cable?

Maybe try using the other connector on the IDE cable, or a shorter cable?

I had a similar issue with an older HD. Switching the IDE cable fixed it, or even moving it to the connector closer to the mobo IDE connection on the same cable.

Worked fine as a slave though
