Editing Apple DAT Drive (section)

=== A/UX ===
Under A/UX on the Workgroup Server 95, the tc tape driver must be accessed in 8K blocks, so tar needs a blocking factor of 16, for example <code>tar -cvfb /dev/rmt/tc2 16 ''file''</code>; without it, tar gives tape write and read errors.<ref name="til16580">Apple Computer, "AWS 95: Using tar with DAT Tape Drive (10/96)", Tech Info Library article 16580, created 21 October 1994, revised 15 October 1996, APPLE_TIL_ARTICLES collection (archive.org), file TIL00001_to_TIL60496.zip.</ref> A later tc driver added support for HP's DAT-2 drive and fixed two faults: the Workgroup Server 95's DAT drive not supporting multiple files on a tape, and tapes that could not be reformatted with mt or Retrospect.<ref name="til17670">Apple Computer, "AWS 95 & A/UX: New Version of 'tc' For DAT-2 Drives (4/95)", Tech Info Library article 17670, created 28 April 1995, APPLE_TIL_ARTICLES collection (archive.org), file TIL00001_to_TIL60496.zip.</ref>
