OK, First, thanks so much for the batch code... Second, I've been modifying it to utilize the fact that I have two CDROM drives. Hence, I just want to put the WinXP disc in the first drve, the Office 2003 disc in the second drive and let the whole process run its course. However, I find that during testing, if the batch finds an "empty" drive, I receive an INT 24 error and it halts the batch. Is there a way to avoid or make this errorcode silent? I've found this Code that calls %comspec% with the '/f' switch which silences the "empty drive" problem. @echo off if "%1"=="" goto _help ctty nul %comspec% /f /c dir %1: | find "Directory of " ctty con if errorlevel==0 if not errorlevel==1 goto _isready echo Drive %1 is NOT ready goto _end :: :_isready echo Drive %1 is ready goto _end :: :_help echo Usage %0 [DriveLetter] :: :_end Is there a way to adapt this to your batch? I think I could modify it at each drive letter call, but then I'd have a long series of checking if each drive letter exists, then checking to see if that drive letter contains the CD with my "detection file".. Is there something altogether different (& easier) that I could use? .....I'm must too tired right now to figure it out..... 8-) Ran P.S. You may wonder why I want this? Well, sometimes I have a number of drives in the computer - some of which may contain unformatted partitions or be empty. Hence, I'd like some way of overcoming this....
