Consider the following scenario:

• You copy files onto a DVD-R on a Windows Vista-based computer.
• The total size of the copied files is less than 130 megabytes (MB).
• You eject the DVD-R without closing the session.
• You insert the DVD-R into the DVD drive of another computer.

In this scenario, you cannot see or access the copied files on the other computer.

Consider the following scenario:

• You format a DVD-R disc on a Windows Vista-based computer.
• You record some data on the DVD-R disc by using a consumer electronics DVD recorder.
• You format the DVD-R disc again on the Windows Vista-based computer.
• You record more data on the DVD-R disc by using the consumer electronics DVD recorder.
• You insert the DVD-R disc into the Windows Vista-based computer again.

In this scenario, the computer does not detect the DVD-R disc.
