I am writing a script to backup a client's server and write the pertinent data to a cd/dvd recorder. On the way, I need to test the state of the device. I have looked at Linux::CDROM, Linux::Mounts, Filesys::Type, Sys:Filesystem, and lastly, Device::Cdio. None of seem to fit the bill and worse yet, Device::Cdio will not 'Build'. (But that's another question.) Objective:
  1. Verify the device exists,
  2. a disc is in the device,
  3. the disc is available,
  4. the disc been formatted (i.e. use growisofs -Z or growisofs -M),
  5. is there sufficient space on the disc, and finally,
  6. did the write to the disc succeed?
Any assist is greatly appreciated...
