Finding a specific Windows volume

It sounds to me like you are running into the same basic problems that
another user was a while back. I posted the following solution which
avoids the errors with locating files on Windows while avoiding disk
errors and system dialogs...

My solution to the same problem is to check for a volume serial number
first, then if there is one, check for the file I'm looking for. You
can do this with the following function...
function GetVolumeSN pDiskLetter
-- Supports both "C", "C:" and "C:\" styles
put char 1 of pDiskLetter & ":" into pDisk
set the hideConsoleWindows to true
put shell("dir " & pDisk) into tDirData
get matchText(tDirData,"Volume Serial Number is
if it is true then
If the function returns a Serial Number, I know a disk is located at
that drive letter. I then do my "if there is a file..." stuff. If the
function returns nothing (empty) then I know there is no disk in the
drive and I don't check it.
This seems to avoid the whole "no disc" error in Windows XP SP2. I
don't know about other versions... you'll have to test it out.
-- End Snip --
This function was confirmed to work on Vista. But unless you can
specify what errors you are getting, there's not much else I can
suggest. Hope that helps.
