I was taking a look at this product that you linked to. The description sounds great--hardware-based encrypted thumb drive for a not unreasonable price.

Although most reviews are good, I am concerned about some of the negatives reported, and I only looked through a few pages of reviews. Random loss of data is one that crops up multiple times. Also the fact that there is basically a "master" PIN code out there that will unlock any Padlock 2--but only once. How many Padlock 2 buyers would know that?

There seem to be reviews from the first version of the Padlock mixed in, too, but even the Padlock 2 does seem to have issues still, like the master PIN.

Actually, since you're actually using the Padlock 2, I suggest you research this master PIN issue, if it really is a universal flaw with this product. Then use it on your thumb drive so that it can't be used to unlock it again in the future since it supposedly only works once.
