SYMPTOMS

After you burn a DVD-R Dual Layer (DL) disc or a DVD+R DL disc in Windows Vista, you may be unable to read the disc. When you try to read the disc, you may receive an error message that resembles the following:

Drive_letter:\ is not accessible.
The disk structure is corrupted and unreadable

When this problem occurs, the disc properties may indicate that the disc contains no files and that the size of the disc is zero.
