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.
