#+TITLE: taperead: read all files on a tape
* Background
Tape storage media generally are made up of sequential, unnamed files.
I had a need to read in the data from my old tapes in order to
transfer it to more modern media. Some of these tapes contained
multiple files - archives of various sorts, backups, etc. I wanted a
script to do so.
This script will read every file on a tape (stopping when it
encounters multiple 0-byte reads from the drive). The files will be
numbered sequentially. Logs from =dd= will be saved alongside the
files for later inspection for errors, etc.
Other than standard Unix tools, ths script also using mbuffer, though
this is completely optional and can easily enough be removed from the
pipeline in the script.
* Usage
Something such as this will do it:
=TAPE=/dev/nst0 taperead=
Files will be created in the current working directory. Additional dd
options, such as blocksize or error handling, may be set with the
=DDOPTS= environment variable. See the comments in the script.
The output will be a series of .bin files representing the contents of
the tape, and corresponding log files representing the output of dd.
If any log files indicate an error, the output from taperead from that
point forth should be considered suspect. (Files may be truncated,
etc.)
Additionally, a file named =sums= will be created with the sha256sum
of every tape file read. These will be verified after the tape is read.
