Help with Hard Drive (s)

By patracy_uk ·
I have 2 pc's with the same mobo's (ASROCK K7S41GX), one of which has worked 24/7 for over 2 years until now but i accept its redundancy. The problem is the second machine, having tried differant HDD's and ribbon cables i keep getting 'ATAPI incompatible'messages and a failure to recognise either HDD or CD/DVD drives.
Both machines are set up identically, I've tried resetting the CMOS etc, jumpers are set correctly on drives etc.
Any ideas please as i cannot see what i am missing and its getting ******** annoying

Are you sure your cables are working properly?

Thanx but yes, I've tried various ribbon cables all to 80 pin spec, as per manual, new and old and including ones from fully opperational machines.

The really obvious thing here is to make sure that the IDE leads are connected the right way around with the red stripe closest to the power plugs on the drives and inserted the right way around on the M'Board.

It's sometimes possible to plug in the IDE Lead the wrong way around on the M'Board. I would also check the Power Supply to make sure that it is actually supplying the correct voltage.

If none of that works remove everything from the M'Board and reseat it, and then remove everything except the Video Card, CPU and try to boot from there you should hear a series of beeps that are telling you that there is no memory present. Once you hear this power down and remove the mains lead and insert 1 stick of RAM and try again to see what if anything happens. If you then get a normal POST Screen plug in 1 HDD on the primary channel and try again, if this works then power down unplug and plug in the Optical Drive and try again.

If it works from there you can start shutting down and installing one bit at a time until it all together and working or fails to boot at which point you will know the problem part.

If this fails I would recommend that you fit a PCI to IDE controller card from Promise Tech as it will work without drivers and then run the Ultimate Boot CD to test the M'Board for problems.

Yeah,I'm w/Hal.You should pull the mainboard from the case,and begin testing on a bench setup.You may have to face the possibility of a dead/damaged controller chipset.That will be revealed by an add-on controller set and known good cables/drives.Good luck.
