DVD drive

Hi usually when the light stays on this means the cable is the wrong way round the same problem occures when you get the floppy drive lead the wrong way round.
If the dvd drive came out of a working computer then the jumper settings were probably correct if the cable can go the other way round try that.
The only other problem you can have is are you building an ibm compatible computer if you are is the dvd ibm compatible if this is also not the problem then the chances are the dvd drive is damaged.
Do you have a normal cd drive in and working if you do try using it in the place of this if this still dont work then i would say the unit is dammaged.
check the leads not damaged but what you are explaining sounds like the lead is wrong way round let me know how you get on ok
