Hey there,
Let me rephrase. Is there a program that can write data and, at a time
interval, erase that data? Perhaps a "ride along" program that carries
Eraser with it, activates Eraser and Eraser deletes the data to DoD
standard.
This isn't exactly what you're looking for, but maybe could be made to
work:
Dead Man's Switch v1.0

<quotes from the page>
This application was sparked by an Ars OpenForum thread about what
would happen if one of us were to shuffle off to that Great
Motherboard in the Sky. Software which would act as a proverbial "Dead
Man's Switch" came up, which is basically a system that, if not reset
by a given time, will automatically carry out a series of tasks, such
as posting messages to websites like Ars, sending e-mails to loved
ones (or hated ones), and encrypting or destroying sensitive files
(*cough* pr0n *cough*). Interest was expressed for the creation of
such software, and well, here it is.
The software is designed to run without installation. Just stick it in
a convenient directory, and it will create all the necessary registry
entries the first time it is run. Any additional files that it creates
will be in the same directory, and will have the extensions .dwp and
..dem, for easy portability.
The software can carry out three functions: posting to web pages,
sending e-mails, and encrypting files (props to WanderingWastrel for
the idea). I haven't tested the webpage posting extensively with all
that many websites, so you may want to test them yourself (there is an
easy mechanism to do so within the program) before setting and
forgetting.
In case the you encrypt files accidentally (forget to reset the
switch, etc.), or if you are testing the system out by manually
triggering the timer, you can decrypt the files using this decryption
program. Just make very sure you remember your password!!!
