IDE cable backwards?

That's all I can think of. :mrgreen:

Nope, IDE cable is connected properly

Are they on the same cable? Maybe both are master, or both slave...(just guessing)

ive fixed the problem ive swapped out the cables, seems as tho the cables were bad, but now when i boot up i get this message:
"Reboot and select proper boot device"

the hard drive is not dead it works fine on another pc also i cant seem to boot from cd or floppy bios settings are all ok.

I would double check the jumper settings on all drives...
Do you have CD and Hard drive on different cables, ie orimary and secondary?

Odd that it does not boot to the floppy...
Set the BIOS to boot to the floppy first.... and see what happens...

What OS is on the hard drive that it works on another PC...
What is the configuration on that PC when you test it... (Only Drive in System?)
Have you duplicated that in yor system...?

Jumper settings are all ok, CD & HDD are on different cables, OS is XP, done all the others things you have specified still no luck.

I can think of only a few causes:

- Both devices on the same interrupt
- Both devices have the same IDE address
- Too much load on the power supply 12 line
- Motherboard or driver board failure

help.. i also have the same problem here. it happened after a power failure. the cdrom sometimes work.

the cdrom works if i dont connect any IDE cable with it.
