Mapping of drive letters to the Personal Secure Drive
During Personal Secure Drive setup, you are asked to choose a drive letter from a list of available letters. This list excludes drive letters currently in use as well as drive letters that have previously been assigned to hot swappable devices or removable drives. This protects against drive letter conflicts.
In addition, seven unassigned letters are marked as "not recommended", to reserve them for future use by hot swappable devices that have not yet been loaded. This protects against drive letter conflicts with additional hot swappable devices.
The number of drive letters reserved for future use by additional hot swappable devices is set in the Windows registry key HKEY_LOCAL_MACHINE\Software\Infineon\TPM Software\PSD\DLSkip. To increase or decrease the number of reserved drive letters, you can edit the value of this key.
Note: The default value for this registry key is 7; the maximum permitted value is 9. If the registry key is set to a value greater than 9, it will default back to 9.
