Abstract
The subject matter of this specification can be embodied in, among other things, a method that includes identifying and restoring corrupted data stored, for example, on a portable media player. Some of the described implementations include synching a media player with a host device (e.g., a personal computer). During synchronization, the host device can query the media player to determine whether any media stored on the device should be replaced. For example, the host device can determine whether a corruption event occurred in association with a media file (e.g., whether the media player skipped the media file as unplayable). In another example, the host can determine whether portions of a media player's storage device are damage or “bad.” If a bad portion is detected, the host device can identify media stored on the portion as corrupt. After identifying corrupted media, the host can replace the media with valid copies.
