CD ROM

By olirosa ·
My computer doesn't recognize a CD ROm (Internal) when is installed, but rcognizes it if I hold it outside.
I tried to installed other CD ROM, but it does not work, freezes the computer, and when I connect the cable to the CD ROM it stop receiving power.
Please, can someone advice on this?

CD ROM

by RRV In reply to CD ROM

when the CD rom is internal check the power supply. check the temperature inside your PC. also the Cable connecting your CD ROM gets disconnected when internal. change the cable power/signal and try again.
the CD ROM drive has a metal piece on its sides. this has to be properly screwed to the metal part of the cabinet which makes the ground. check if this is proper. or give a small wiring to this metal piece to ground so that CD starts working properly.

Good Luck

1. I guess you mean an external cd-rom with 'outside' yes? Then you should try connecting it to the inner connector of your IDE cable, using the secondary controller. Be sure to have the CD-ROM set to slave! These days most CD-ROMS are shipped beingset to 'Cable Select' by default. But if your IDE chipset and/or BIOS does not support this, then the PC crashes, or just says that no CD-ROM has been connected.
You can then, switch BIOS settings of the secondary slave to 'none' or 'auto'. The first is more reliable with system drivers setting up the controller, the second one enables CD-ROM Auto-Boot at startup, if you ever need that! But most modern PnP BIOS will find the CD-ROM even if you switched the port off!
The rest relies on your hardware.

2. You just hold the internal cd-rom outside the case? Well, if your CD-ROM stops receiving power once connected, then please turn around the connector! CD-ROM drives shut down when connected the wrong way. If this is no solution, then check the connector (both on cable and cd-rom, IDE+power) if any of them is broken and gets contact to the metal case!

Please make sure that the outlet to which you are connecting your PC has the proper polarity and is grounded. For example, in the US the wider blade is neutral and the third prong must be grounded. The second CD-ROM you tried may simply have had itsdata cable connected backwards. Usually you see strange behavior when this happens, like being unable to eject, or the drawer hangs open partway, or the hard drive light stays on.

You didn't mention if you had IDE or SCSI. IDE is 40 pin, SCSI is 50.

If you have SCSI, please make sure termination is set properly. If the CD-ROM is the last device on that cable, it should be terminated. There is usually a jumper on the back of the drive for this.

IDE is very different. As another tech suggested, please set the CD to slave if a hard drive is connected to that cable, and make sure the hard drive is set to master. If the CD-ROM is by itself on a cable, set it to single or master.

I don't know if this help, but give it a try.
- Check all the cables connected to the CD-Rom drive, and their connection with mother board too, to see if there is any loose. You may want to try another signal cable to see if it's the problem too. - Check the jumper on the CD-Rom drive as well as other drive(s) that share the same signal cable connected to the mother board. Make sure that they are set as one master and one slave. Normally new drives are set at master, so may be you didn't change the jumper before install the new CD-Rom.

Good luck,
