I wanna make a program that backups some files to a floppy.
Is there any way to check if there is a disk in the floppy drive?

I guess I could try to copy a small file to the disk and use the @OK() function, but is there another way to do it?

You could do something like this:

Great idea. Should have though of that myself Laughing

Thanks again Dr.D Wink

Just thought of something else...

What if a user inserts a non formatted floppy?
Than it won't have any diskspace.
Any chance of detecting if the disk is formatted?
Maybe using the filecopy process I mentioned above with the OK function with the volinfo function?

an alternative,

Nice, thanks Serge.
Will that work if the disk isn't formatted aswell?

The code I posted checks for the disk size of A. If the disk is unformatted is won't report any
size, so an unformatted disk should behave like no disk.

You could just adjust the message .. please insert a formatted disk bla-bla..

no idea geotrail - i would have thought that all the floppies one buys today are pre-formatted

give my code a go with an unformatted disk and see what it says - i've never tested it that way

If you make a boot disk for linux and try to access it with windows you'll be asked if you want to format the disk. That's why I'm asking.

But I guess I can just adjust the message telling it to insert a formatted floppy disk. Wink

Why make it harder than it is Laughing

The @volinfo() function will prolly act differently on a non
or different formatted floppy. Check @ok() afterwards.

If not, ya might try some file access commands such as
the DOS "dir" command or VDS "LIST FILELIST", then
check @ok()... Wink

I've used @volinfo(,S) for a similar task. Return will be NULL if the disk is not present, not
formatted or otherwise inaccessible. Haven't had any error reports on that account..
