While checking out DriveCrypt I came across another product which looks similar and possibly more easy to use for the EU. It's called safehouse and can be found at pcdynamics.com. Does anyone have any experience or opinion on this product. I appreicate all the input I have received so far. Thank you.

EFS only encrypts specific files and folders. Also the keys are local on the
hard drive (silly thing that). EFS ist not considered secure (at least not
by anyone that i know.) It is designed for transparent encryption to prevent
one user of a computer from accessing files from another. If you should
decide to use it make sure to designate a recovery agent. Otherwise the
files are lost should you delete or lose the profile.

I recently was looking for a similar solution, though i needed something
more complicated (search this group for my posts with title Secure Boot
Manager if interested) and found 2 excellent products:

Safe Boot Pro/Enterprise from www.safeboot.com
Drive Crypt from SecurStar GmbH www.drivecrypt.com

Of those two i preferred safe boot. It is also a true enterprise solution,
allowing you to remotly manage machines, create groups, install the
software, and change settings from a central console. We did not end up
buying it, but i would have recommended it had it fit my peculiar needs (was
trying to hide 2 OS's from one another)

Hope this was a help,

Ethan-

Windows 2000 (and XP Pro) have this functionality built in (It's called
EFS - or Encrypting File System), and it is designed for EXACTLY the
reason you specify.  It requires that the hard drive be formatted as
NTFS, and one of the previously mentioned Operating Systems.  Microsoft
has written up a decent overview of the functionality and setup at
<http://www.microsoft.com/windows2000/techinfo/planning/security/
efssteps.asp>.

Windows 98 is NOT a secure operating system by ANY stretch of the
imagination and you can not use EFS with it.  Even password protecting
the machine offers you NO protection, as you can bypass the password by
simply hitting the escape key.  You could upgrade these machines to
Windows 2000 or XP, or someone else on the list may know of a third
party utility that may provide the functionality you are looking for.
Good luck,

-Sean
