Ghost 14 Recovery Environment does not see my USB External Drive

The Ghost 14 custom recovery disk boot environment doesn’t see the USB drive where I saved my recovery points.  The external drive is a Maxtor One Touch 4 (750GB) about a year old and works fine in every other respect. I’ve made multiple recovery disks to ensure that the drive was attached and functioning at the time. The drive seems to use native XP drivers (disk.sys, PartMgr.sys) and doesn’t require special/custom drivers. Any thoughts? My recovery points and my process for periodically rebuilding my machine (the reason for buying Ghost 14) are worthless without a solution.
