After a failed attempt to format media, the system may experience unusual behavior. The symptoms are:

• The computer will not recognize disc changes.
• The computer cannot read data from a disc.
• The icon in My Computer for a disc does not change at eject.
• Windows AutoPlay stops working.

If the user attempts to format dirty, damaged, or worn out media, the format will fail. This is correct behavior on invalid media. A message is displayed to the user saying that the format failed, either due to media damage or due to a general failure. After the invalid media is removed from the system, one of the following unexpected behaviors may occur.

• The computer will act as if a blank disc is still in the drive.
• The computer will act as if a disc containing unreadable data is in the drive.
• The computer will not read other discs inserted into the drive.
• The computer will mount writable media as read only.
• The computer will not activate Windows Autoplay.

Any of the following systems running Microsoft Windows 2000 or XP configured with Drag-to-Disc (DLA) version 5.1 or 5.2 :

Rebooting the computer without bad media in the drive restores normal operation. Discard the bad media.
