Wet SD cards (Terminated)
I am writing some programs for use in PDA's in potentially wet environments (fish traps). I wanted to make sure that the data on the SD cards would survive immersion, so I took a card and left it in a glass of water for a day: No harm done.
That test may not have been very definitive. Tap water in a glass is not a terribly harmful environment. Somebody on this site told me about leaving a chip in a glass of orange juice for an hour (citric acid and sugars, more conductive than tap water). Now I'm thinking of more severe tests:
Flat coke (pH 1.8, so it's more acidic than stomach acid)
Washing machine: Front loader, so there would be agitation, soap, and dirty socks.
Dish Washer: Heat, pressure, soap, spaghetti sauce.
Any thoughts?

Remind me to never let you borrow my laptop :)
Re: Wet SD cards (Terminated)
My laptop was stolen :( , which is a pretty effective way of losing data, too.
By the way, I'm back at it again. This time I won't boil the card, but I am going to try warm salt water. However, the basic plan is that an n of 1 is not very convincing, so I'm going to put the tongs to another one.
Re: Wet SD cards (Terminated)
I think the main problems will occur if the card in on power when it comes into contact with water.
Also maybe a PDA that takes two cards would double your chances of one surviving.
Re: Wet SD cards (Terminated)
That's true, if the card is in a PDA, it may lose data whereas a card that is not in a PDA would not. However, I don't really want to test that out, it's more than my budget would be happy with.
