Lost one of my drives

Hi Folks,

I hope someone can help me with this one. I run WinXP Pro on a Asus K8V-MX motherboard with an AMD Semperon 1.8Gig processor and 1 Gig of ram. I have an 80Gig Western Digital C drive with a 180 Gig drive on IDE bus 1 and and Liteon DVD and a Seagate 180Gig drive on IDE Bus 2.

This all started when I recently installed a new Liteon DVD on my secondary IDE bus and the DVD wasn't using DMA, it was using PIO instead. So using the device manager via my computer, I uninstalled the secondary IDE bus and re booted without the Seagate drive, in order to get DMA on the Liteon DVD.
That all went well and the Liteon came up With DMA 4 when I checked the properties. However when I reattached the Segate drive and checked in my computer, it came up with local disk E:, but there is no disk size or free space listed for the drive. XP says its an unknown device and I can't access the files.
I know the files are all still there, about 100 Gig of 'em, but does anyone know how to restore the drive to its former working state.

Thanks if you can help.

The setting you have changed is the PIO on IDe BUs 2, so try changing it back.

 

The Seagate drive had DMA 5, the only pio at the time was the Liteon DVD.
I tried changing it back to no avail.
