This is a HUGE problem, norman.
What's worse, XP Pro and XP home do NOT treat discs the same way, so
if you have code that scans for drives, and ignores empties, it is
likely to work properly on XP Home, but not the same on pro, where it
will inform the user that the drive is "empty".
We found and revised some code that used the kernel to do this, but
it the behavior was not consistent between xp pro/home.
I'll see if I can dig it up, but we ended up pulling drive scanning
out entirely and just asking the user to locate the media/drive they
wanted to use...pretty much like the majority of Win32 apps do :)

On OS X these count actual mounted volumes.
On Windows this seems to count "drives".
I have a PC with 2 hard drives and a multi-port media reader, a DVD
drive and a CD.
Except for the 2 hard drives none of the other devices has a CD,
DVD or other media cards in them.
A loop like
dim i as integer
dim limit as integer
limit = VolumeCount - 1
for i = 0 to limit
listbox1.addrow volumes(i).absolutePath
next
lists only the actual volumes on OS X
On Windows I get and entry for every device regardless of whether
it has media in it or not.
Is that "correct" ?
Seems a rather huge distinction between the two platforms.
That's one issue.
However, on Windows IF I happen to hold a Folderitem for each
volume and a person ejects a volume, how do I test the folderItem
to see if it is valid any longer and NOT get the "There is no disk
in the drive Abort Retry Ignore" dialog ?
I've tried FoldereItem.exists but that seems to prompt for a disk
when the drive is empty which is what I really want to avoid.
Is there any way to tell if a Windows "Volume" has media in it ?
