1. "Ejecting" a USB device

#13574

Posted by: DougA 2012-01-17 05:03:27

I have an application that reads files off of a USB card, then erases them. (which updates its directory)
I'd like to initiate the "eject" function, to be sure the card doesn't get corrupted, and so I can then safely insert the next one.
Anyone know the code I can use to accomplish this ?

Doug

2. I googled using "safely remove usb windows programming"

Found a number of options (haven't tested any).

There was a freeware there that might be useful - http://www.uwe-sieber.de/drivetools_e.html

Try the RxAudioCd add-on as so:

LIBRARY rxaudiocd
/* Assume USB is "D:\" */
IF cdopendevice("DriveHandle", "D") == "" THEN DO
   /* CdOperation(DriveHandle, 'UNLOCK') */
   cdoperation(drivehandle, 'EJECT')
   cdclosedevice(drivehandle)
END

If this doesn't work, I should be able to come up with something else.

Thanks Jeff, however, the 'cdopendevice' function returned "incorrect function".

Michael, while i would prefer a function, i did download the 'RemoveDrive.exe' and it does work.
Thanks for the link, here's the code i tested

Library RxCmd
RemoveDrive_exe = "E:\Install\ReginaldREXX\RemoveDrive\RemoveDrive.exe"

error = command(RemoveDrive_exe "D: -b")
