[. . . ] · Restored errors ASC = 15 ASCQ = 00 Key = 04: Got the media back in the state before move, but something is wrong with one of the elements. Other moves might be able to complete successfully. · Recovered errors ASC = 0 ASCQ = 00 Key = 01: The unit should be able to continue successfully. B-22 Appendix B Programmer's Tips TapeAlert Specifications TapeAlert Specifications Overview TapeAlert is based on the tape drive/library performing constant self-diagnostics, and then returning high-level error flags. TapeAlert allows any storage software application using TapeAlert capable tape drives/libraries to access standard diagnostic information. [. . . ]
