Checking for media in drives

[Ken Ray]

Jack,

You can use the DriveReady command line utility at
http://www.jsifaq.com/dl/drvready.zip. It must be run in a batch file
though, so create a batch file like "testa.bat" and put the following in it:

  drvready.exe a: /q
  @echo %ERRORLEVEL%

Then call the batch file from the shell() command in MC. If it returns a 1,
there is a disk in the drive. If it returns a 0, there is no disk in the
drive. It does it silently, so there's not error dialogs or "please put in a
disk" dialogs.
