However, that aside. this might be a permission problem. I assume that the device name is the same as the one you are using with dd and that you have reviewed: http://www.jbase.com/knowledgebase/manuals/3.0/30manpages/man/sup12_TAPE.htm Make sure that /dev/nst0 works with dd as well as /dev/st0, that the label spec is correct and the tape device is configured for variable length blocks. Overall, if you have the disk space, it is easier to dd the tape image into a disk file, then T-ATT FILE to read it.
