FYI, I have also heard that BIOS updates can often times resolve this type of problem with Bootguard not recognizing the USB Device while docked. If you haven't done that, it's worth a try. Also, often times your docking station will haev firmware updates.
If you have tried all of the above (updating bios, updating firmware on the docking station, installing PGP Desktop 10.2) and you still have problems. Post as many details as you can about your hardware setup
Examples of this info would be:
- laptop make/model and part number if possible,
-docking station part#/model#
-BIOS version of the machine
-what version of PGP Desktop you have
-whether the disk is encrypted
- what language version and keyboard regional setting you have installed with Windows
