I would like to run a program that asks the user to insert a floppy, and after one has been inserted, reads and writes to the disk. I have written code that can read from a floppy disk, but inserting a floppy normally couses the Mac to mount the disk. How can I turn off the auto-mounting? Once my program has finished reading and writing the disk, how do I eject it? At this point, the disk is not mounted. Will PBeject work anyway?

After you put up a dialog to prompt the user to insert a disk, try calling GetOSEvent() instead of GetNextEvent(). GetNextEvent actually calls GetOSEvent and then calls MountVol() to try to mount the disk. After you're done you can call PBEject() to eject the disk... steve -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Steve Christensen Never hit a man with glasses. stevec@apple.com Hit him with a baseball bat.

You have to override using the driver to do that (the same way as
you would read an MS-DOS floppy)
But how do you propose to read/write to the floppy if you haven't
mounted it ? Normal read/write calls won't do...
What _I_ want is an utility that runs under MacOS that reads/writes
tar floppies (or cpio, or just plan _files_) to be used from A/UX.
Happy hacking,

No. Just because a disk isn't mounted doesn't mean you can't read or write to it. Drivers don't care if there's a file system around to mount a disk. All they do is read and write blocks on the disk, which is exactly what he wants to do. In fact, the disk could be mounted when it's inserted, and then his program could explicitly unmount the disk before doing the reads and writes so he won't collide with what the file system is doing... steve -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Steve Christensen Never hit a man with glasses. stevec@apple.com Hit him with a baseball bat.
