When I wrote that I was thinking of how the Amiga handles floppies.
You can eject a floppy disk in the middle of writing a file to it. The
Amiga patiently puts up a non-blocking message explaining that it hadn't
finished writing to the disk and asking for the disk to be reinserted.
You can then put the disk into a *different* floppy drive attached to
the Amiga and the computer will notice that it is the disk it is waiting
for, and continue writing to the disk. This is done without corrupting
the floppy's filing system.
It seems to me that we could really use this kind of behavior in Linux
for USB thumb drives.
I have to admit I haven't tried ejecting floppy disks on Linux or
MSWindows during writing. There is not much call for floppies anymore
and my computers have taught me to be their obedient servant.
It would be nice for our computers to do what *we* want them to do
rather than us having to learn to act like computers for the convenience
of our tools.
My time wasn't completely wasted last year.
I went on a 940 million kilometer journey.
