Unable to write to the disk

There is a general problem writing to a disk. This error has the following causes and solutions:

• The disk drive door is improperly closed.

  If the disk is removable, check the drive door. Close it properly if necessary.

• The disk may be inserted upside down.

  Reinsert the disk right-side up.

• The disk may not be properly formatted.

  Reformat the disk if you are willing to lose the data it currently contains.

• You are experiencing network problems.

  Try restarting your network.

• You placed a disk of a certain density in a drive that can't write to it.

  Use a different drive or copy the material you want to a disk that can be read on your drive.
