Uninstall, Can't find Disks

I am using the CDE for the first time, version 1.2.114847.152
Encrypted 2 external Drives and now the Drives are not there, and I am getting an Error "Problem with the Encryption Subsystem OS Vista Ultimate.
Won’t uninstall, it tells me to remove all Encrypted Partions, can’t remove it if I can’t find it.
Can’t format the Drives either, Windows cannotcomplete Task.
