As already mentioned, jumpers are the most likely reason but you say it doesn't 'reboot' (boot up?) with the cdrom attached. Does that mean when you start it up with the cdrom attached nothing shows on the screen or do you get a normal posting screen or logo and then it stops, perhaps with an error message?

Usually a misplaced jumper will give the latter results but if you get nothing when starting it up there may be a hardware problem with the cdrom or possibly the IDE cable.

check to see if the jumper pins are set correctly on the HDD and the CD-ROM drive. One will need to be Primary/Master and the other will need to be Secondary/Slave. I usually like to use the Cable Select (CS or C/S) jumper pin option because you usually don't have to change it from that.

See page 2 on the link below for info on WD jumper pin settings

Whenever possible, it's generally best to have drives separated. If you only have the 2 IDE devices, the HDD should be the primary master & the optical drive should be the 2ndary master. If that's not possible & they must share the same cable/channel, the HDD should be primary master & the optical primary slave. Personally, I prefer not to use Cable Select but if that's the route you wanna take, both drives should be jumpered to CS & the HDD should go on the end connector, the optical on the center connector.

You'll have to look at the rear of the drives to determine the correct jumper placement:

Just to add, if you dont have IDE please provide make/model of workstation/server, and what type of cabling you are talking about.

Thanks.

jpag: since SATA connectors use one connector per device, it is pretty obvious that the OP is talking about IDE drives. Anything else would be MUCH less likely.

You have to be a little bit crazy to keep you from going insane.
