How do I determine if Floppy is in drive? I assume there is a interrupt 13 function that will do this. Running msdos 7.1 from a program (VB dos) I would like to check if a floppy is in the drive. Without the Retry,Fail,Abort message. A bit of code any language would help. An example would be the VOL command. VOL A:

Hi Would something like this work. If there files on the disk you could change the first line to :- if exist a:\*.* goto found. if exist a: goto Found echo Floppy Not Found goto quit :Found echo Floppy Found :quit

You can invoke a 2nd command.com with the undocumented /F switch which specifically is supposed to answer F for Fail to all errors created under that instance of the 2nd Command.com. What really happens is that you've got a broken new command.com instance that rarely does what it used to. Read buggy as buggy can get. But this appears to work here? @echo off command /f /c vol a:|find "label" if not errorlevel 1 goto no_disk :disk echo we gots a disk in it. pause exit :no_disk echo there is no floppy inserted pause exit

under dos 7.1 (no windows) the following works ------------------------ @echo off ver command /f /c vol b: | find "Ser" > NUL: if errorlevel 0 set srcdrv=0 if errorlevel 1 set srcdrv=1 if errorlevel 2 set srcdrv=2 @echo the error level %srcdrv% if errorlevel 1 goto no_disk :disk echo we gots a disk in it. goto ppp :no_disk echo there is no floppy inserted :ppp - This is the output ---- without disk in drive --- C:\>test Windows 98 [Version 4.10.2222] Not ready reading drive B Abort,Retry,Fail?the error level 1 there is no floppy inserted C:\> ---- with disk in drive --- C:\>test Windows 98 [Version 4.10.2222] the error level 0 we gots a disk in it. C:\> _____________________________ In a Microsoft Windows 2000 [Version 5.00.2195] Command Prompt window the above does not work as the errorlevel return is always the same 0. But my problem was / is strictly with a DOS environment. So my work around in VB Dos was the following: FUNCTION FloppyIn (drv$) AS INTEGER DIM a$, b$, i%, j% DIM DirFile% FloppyIn = false 'assume NO SHELL "command /f /c VOL B:> Q:\$DELETE$.ME$" DirFile% = FREEFILE OPEN "Q:\$DELETE$.ME$" FOR INPUT AS #DirFile% DO UNTIL EOF(DirFile%) LINE INPUT #DirFile%, a$ i% = INSTR(a$, "Serial") IF i% <> 0 THEN FloppyIn = true EXIT DO END IF LOOP CLOSE #DirFile% KILL "Q:\$DELETE$.ME$" END FUNCTION ============================ meelee5, Thanks - working code is always beats elegance. This does throw some junk on the screen but that can be hidden. I was playing around with interrupt calls that would sort of work in a windows command prompt window but not in DOS. again thanks!

Dack: You should try dready.com Usage: Dready.com [drive] Example: --------- dready a: if errorlevel 2 goto nodisk ---------
