- I have used the backup program in PC-Tools, and it works the same way:
- the drive light stays on even while you change floppies. This is
- accomplished, in fact, by keeping the motor running, or rather, by
- trying to read or write to the floppy (which requires the motor to be
- running, of course).
-
- A much better way to solve the problem is to have some kind of volume
- labels for filesystems on removable media, and have the kernel check
- the volume label before reading or writing after a media change. This
- doesn't put wear and tear on the hardware, only on your friendly
- kernel hackers. They have, incidentally, already at some time
- discussed this, but nobody seemed interested enough to do it at the
- time. I'd do it, but I'm not a kernel hacker. Anybody interested?
