Abstract:
A method, programmed medium and system are provided for recovering media-stored program code and/or user data when data on the same media are lost or corrupted. The system includes retrieving user data and/or program code from an external source when the actual data/code is not readable. When initiating the load of local storage, an initial scan for damaged regions is performed. If the initial scan determines that there are damaged/bad regions, the media player will look for the necessary data and/or code to patch the digital media. In one embodiment, a hardware or software look-ahead reader function, for example, is enabled to retrieve the original undamaged data/code from the local storage when an attempt to read a region from an optical disk fails due to a bad region. If the region in question is not stored locally, then a request is automatically transmitted to the original data provider to re-send the original data/code, which may include original program code. The data provider will then respond by sending the missing data/code to the user system where it will, in turn, be stored within the local storage device for further access and use.
