Sony PCG-NV100 - Manual (Page 164)

The application cannot find a file while a PC Card is inserted.
When inserted into a computer that is connected to the docking station, some PC Cards may change the drive letters of the
disk drives in the docking station. If this occurs, an application you are using may not be able to find files.
To correct this condition, do one of the following:
 Remove the PC Card, and restart your computer. Do not insert the PC Card while using that application.
 Change the drive letters of the disk drives of the docking station or of the PC Card. Refer to the Windows ® help files
or the application manuals to change the drive letters.
