This directory contains a mapfile of a multisession CD, with two sessions. The first session houses music, in eleven audio tracks. The second session is a data session that houses a file system. This type of storage medium is known to behave poorly with some acquisition methods that otherwise function for floppy disk, hard drive, or flash medium. In particular, audio sessions do not image as data sessions do. On this disc, the audio session appears to the imaging ddrescue process to be only erroneous sectors.
