No Disk error & MountedDisks

[FlexibleLearning at aol.com]

Hi Alex:
 
Try asking for a file or directory  in the A: drive or any removable  which 
is not mounted. I'm also using win2k with engine 2.6.1 (as used by  rev2.5).
 
/H

I haven't had any problem like this; in fact, I can't find a way  to get a 
'No disk' error message.

This is with Rev 2.5, win2000  pro

>  get (there is a file tPath)

Returns 'false' for  everything I can think of, including
d:\nosuchfil.txt
g:\nosuchdisk.txt
g:
nonsense:\nonsense.txt

What do you do (or which variant of Windows) gives  the error ?
