IBM Tape Diagnostic Tool 9. Writes two filemarks. 10. Backward spaces two filemarks. 11. Backward spaces number of records written. 12. Prints amount of data to read. 13. Issues read command. 14. If read error occurred or number of bytes read is different from requested number of bytes to read, go to Step 19. 15. Compares data read with data written, show miscompares and if miscompares exist, stop (go to Step 19). 16. If compare is Ok, print ok message. 17. Forward space one file mark. 18. Repeat Steps 10 to 24 until all blocks are written. - OR Go to Step 4 on page 333 until all blocks are written. 19. Prints current block id and total number of bytes written. v The following are the Read Only steps: 1. Issues a Read Position. 2. Sets block size. 3. Generates special pattern. 4.
