| |
I am trying to figure out how to detect insertion of media (such as a CDROM, floppy or zip cartridge) without noticeable physical hardware activity. For example, I would like to bring up a CDROM icon as soon as the user inserts a CDROM without the user having to do anything else to bring this to the computer's attention, just like under Windows.
Simply trying to read a byte every second from /dev/fd0 or the CDROM device is unacceptable, because that causes the floppy to spin up and make a lot of noise and causes the cdrom drive to retract its tray.
I don't believe that there is currently any ioctl defined or this purpose or even a defined way for kernel code to get this information from a device driver, but I'd like to know if there is.
Any pointers would be appreciated.
