Neither drive works when I plug one in..

[dmw16]

I had my PSU go a few days ago. So I got a new motherboard(Epox 8RDA) and one of my hard drives works fine (WD 120gig w/ 8MB cache). But when I plug the other drive (WD 120gig w/ 2MB cache) neither one recognizes. I checked the master/slave settings and everything appears right. I know both drives are good because when I plug them both into the ata100 addin controller on my other older motherboard Asus A7V both drives are recognized and I can access data on both of them. What gives?
thanks,
-doug

Could it be the HDD controller on the EPOX is f'ed up?

could be...
well it appears he is just swapping drives willynilly ..could be..or could be an OS issue,jumpers,etc. like I'd said ...info ..more of it..is needed..

OK - try setting both drive's jumpers to CS, and then connect them with an ATA 100 ribbon - black to Drive 1 and Gray to Drive 2.

Sounds like the problem I had with my WD 400BB drive, nForce2 doesn't like some WD drives.
My 128/8meg also works, don't have a 120/2meg, but it sounds familiar.

There's a workaround, snip one of the wires on the ribbon cable...going to look around and see if I can find that info for you.

Found it....from this thread Quoting NesuD:

"Wrong Western digital drives are not all compatible and i am very capable of setting one up right. Theres is a problem at the drive detection with SOME not all WD drives that will hang the system at post. This problem is acknowledged by WD. The dirty fix for it is to cut the pin 1 wires on the ide cable apparently the issue is associated with the reset. Western digital will send anyone a modified cable that has this problem. here is the response to me fro WD tech support:

I apologize in the delay in answering your emails. I phone the records and there was a request to send you a modified cable I am not sure why you have not received the cable yet, however I have requested another cable be sent to you. This issue affected only a very small about of drives and has been correctly.

We did identify a timing anomaly with a certain BIOS, where the drive is not recognized by the system on power-up. During the drive's power-up initialization, before busy is cleared, there is a very small timing window during which a reset may cause the drive to become inaccessible. This affects only an isolated group of WD hard drives. Western Digital has since optimized its hard drives' power-up initialization sequence to ensure compatibility. This optimization does not cause any functional changes with the power-up initialization

The cable that we send will work with this drive and other IDE devices there are no performance issues related to the new cable or issues with other devices recognizing on the cable.

IF that's the problem there's the solution. Easy way to find out is to snip the wire on an old IDE cable and see if you can get the 120/2meg drive to detect then. This page will show you what's pin 1 if you're not sure.
