Password protecting a memory stick

Thanks very much for the reply, Rod. Looks to be just what I need.

Hi there,

As it happens my son gave me an Xmas present which I think fills the bill.

He gave me a “datashur” 8GB stick similar (but larger capacity) to the ones he uses for his work. I has a keypad to enter a PIN and hardware encryption (to military standard) of the data. Once unlocked it appears as a normal USB stick so no software is needed and it will work on any OS that can use one. Eject it and it locks up automatically, so if you lose it your data is safe.

I believe they are quite pricey compared to the common or garden variety, but how much is your data worth to you? I know that they sell them on Amazon and other places.
Hope this helps,

Rod.
