Thanks for the detailed info about the dip switches. My manual lists all but DIP #7 as reserved. > > 3) Has anyone else using an AIT tape drive had similar problems? > > Not me. > > Did this problem recently start or have you never used it before? > Are the tapes new or old? > What is the exact error you're getting? > Can you tar or dump directly to and from the tape without errors? > OS and version? This problem existed ever since I tried to do my first resetore from tape. All of the tapes are less than 4 months old. I receive 2 error messages. When using amrecover, I receive an error message to stdout as follows: Extracting files using tape drive /dev/nst0 on host bender. Load tape BACKUP-22 now Continue [?/Y/n/s/t]? y <snip as restore begins> ./r50/bin/MSFD_UTILITY.EXE ./r50/bin/PDM_SIMULATION_APPLICATION.EXE ./r50/bin/PGS_CRITERIA_VALIDATOR_DRIVER.EXE tar: Skipping to next header tar: Archive contains obsolescent base-64 headers tar: Error exit delayed from previous errors extract_list - child returned non-zero status: 2 Continue [?/Y/n/r]? y amrecover> exit 200 Good bye.
