I keep a pair of Eagle USB notebook drive enclosures (one IDE one SATA)
in my notebook bag along with several 8gb USB drives that carry my driver collection
I have Enclosures for both IDE and SATA desktop drives that similarly I exclusively use as tools.
a typical USB notebook drive enclosure to allow you to "Rescue" files
will only cost you about $15 or so.
a bit cheaper if you shop ebay carefully.
