Has anyone really set up a USB disk drive for SHTF purposes. Personal SHTF is just as important and more likely to happen so I am working on mine now. Should something happen to me I want my family to have reasonably easy access to this info. In fact, I'll provide password info to get into this drive instead of my safe code (it'll be in the drive for family to get when/if needed).
I only have a 2GB USB drive and hope it's large enough. For critical data I'm sure it is but I will have a few applications on the drive as well. I'm using this as a start but adding and subtracting some stuff. It was posted to the ARFCOM Survival forum by ar-jedi (maybe).
Here is a more recent thread.

wallet/
- scans (front and back) of everything in my wallet, incl credit cards, DL, NJ FID, social security card, employer ID, healthcare cards, etc. note that it's important to scan the back as there is always useful info there -- for example, generally the "report lost/stolen card" contact number for your credit card company is on the back.
