Have you thought about doing a repair installation? Boot off the XP CD,
choose install, chose R to Repair, and let it do its thing. Seems like
you have tried most everything else. And yes, the DMA if available
should be under the ATA\ATAPI Devices-Primary (or Secondary) IDE

Then reinstalled the HUB and Externl drive. The drive shows up in My Computer and Device Manager but is missing from Disk Manager.
