[wplug] degaussing tapes and hard drives

[Poyner, Brandon]

If you CPIO or any other software to write anything to these tapes they will throw an I/O error within the first few meters of the tape.  This is effectively the EOT when writing.  The operating gets the interrupt from the tape drive and refuses to write any more data.  I'm unable to write beyond that point, even though there is old data that can presumably be read beyond that point (splicing, for example).  Unless you know of some trick to get around these physical media errors I don't think CPIO will cut it, nor will any other piece of software.

	   IMHO, I differ with this statement.  CPIO  hundreds of compressed copies
	of the /bin and /kernel (non-user) directories to a tape, until you reach
	EOT, and you'll drive the theoretical data recovery people sane.
