Re: Encryption of harddisk
- Hi James,
I'm seeking the same thing. I'm now using a 60GB notebook hard disk
(5,400 RPM - fast for notebook HDD), in a small external case. The idea
is that when I'm at home, I can plug it into my NSLU2 and share it
between several PCs. When I travel, I can just hook up the tiny drive to
my laptop via USB and carry my files/mp3s with me.
Since the data contained would be the same stuff I'd keep on my desktop,
it needs encrypting so that if it were lost/stolen whilst travelling,
I'd have a level of protection.
To avoid excess processing on the Slug, I think I'll create an image
file of a filesystem, then use the Slug's samba to share it. I can then
mount the image on each client PC and use it that way.
I hope that makes sense?!
