HDD adapter to non-laptop machine

[Harry Putnam]

I recently upgraded my tosh 4005CDS HDD from 3.9 to an 8g.
I now have the old (still working) HDD and would like to get some use
out of it.

Anyone know if there is such a thing as an adapter of some kind to
allow a regular pc to access the laptop HDD.  I've heard it mentioned
in discussions about security on laptops where someone always says
"They can just take the HDD and access it with an adapter"

Now I'm looking for such a critter but no soap.
