GNU ddrescue is a data recovery tool for disk drives, DVDs, CDs, and other digital storage media.It copies raw blocks of storage, such as disk sectors, from one device or file to another, while handling read errors in an intelligent manner to minimize data loss by scraping good sectors from partially read blocks.
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.

CD-R, DVD-R, DVD+R, CD-RW, DVD-RW, DVD+RW and DVD-RAM discs are all affected by exposure to ambient heat as well as heat build-up due to direct sunlight.

DVD recorder drives can be used in conjunction with DVD authoring software to create DVDs near or equal to commercial quality, and are also widely used for data backup and exchange. As a general rule, computer-based DVD recorders can also handle CD-R and CD-RW media; in fact, a number of standalone DVD recorders use drives designed for computers.
A single-layer Blu-ray disc (BD-R and BD-RE) has a capacity of 25,025,314,816 bytes, which are 23,866 MiB. A dual-layer Blu-ray disc (BD-R DL and BD-RE DL) has 50,050,629,632 bytes, which are 47,732 MiB. This is exactly twice the capacity, unlike dual-layer DVDs, which only have less than twice the capacity as single-layer DVDs. [24]
