hi AK_C,
To have a PC 'see' a local drive as an additional drive letters, two choices:
1) In disk management, you may be able to assign a second drive letter
2) From a command line, you should be able to use the 'SUBST' command.
and off-topic, older members of the forum may suspect that by using A: for your data, you have a very tiny data set! as A: used to be the boot or first floppy drive on a PC ! :-)
