Can a volume be automatically mounted whenever I log on to Windows?
Yes. To do so, follow these steps:
Mount the volume (to the drive letter to which you want it to be mounted every time). Right-click the mounted volume in the drive list in the main TrueCrypt window and select 'Add to Favorites'. The Favorites Organizer window should appear now. In this window, enable the option 'Mount selected volume upon logon' and click OK.
Then, when you log on to Windows, you will be asked for the volume password (and/or keyfiles) and if it is correct, the volume will be mounted.
Alternatively, if the volumes are partition/device-hosted and if you do not need to mount them to particular drive letters every time, you can follow these steps: Select Settings > Preferences. The Preferences window should appear now. In the section 'Actions to perform upon logon to Windows', enable the option 'Mount all devices-hosted TrueCrypt volumes' and click OK.
Note: TrueCrypt will not prompt you for a password if you have enabled caching of the pre-boot authentication password (Settings > 'System Encryption') and the volumes use the same password as the system partition/drive.
