Protecting flash drive in US-Mail?

Protecting flash drive in US-Mail?

Protecting flash drive in US-Mail?

Not sure, if this is the correct forum, but here goes...

I have received a SD card from my brother i Arizona.
The drive appears to be completely defective upon arrival (does not show up at all), but working before it was mailed.

According to this:
US-Mail may use X-ray devices, that can have destroyed the card.

Question now is, how to protect such electronic devises from radiation in the future?

An idea that just popped up is to wrap it completely in Al foil. Possibly several layers with plastic or paper insulation between.
But what do the experts say?

RE: Protecting flash drive in US-Mail?

Being wrapped in plastic, very low humidity, and the vibration of shipment can create a huge static charge. Foil wrap would protect from this as well. Film pouches that made from lead foil used to be available so your high number ASA film would not get fogged by X-ray scanners. If you think it is X-rays, you could try one of these

Of course, foil will also keep your leftovers fresh and keep aliens from reading your thoughts: bigsmile http://www.youtube.com/watch?v=w-0TEJMJOhk

RE: Protecting flash drive in US-Mail?

Have you checked it more than one device?

It would be pretty awkward if the USPS systematically destroyed all flash memory chips as part of the process, what with online shopping and all.

RE: Protecting flash drive in US-Mail?

What was the verification that the card was working originally? There were a spate of counterfeit SD cards being sold online a bout 3 yrs ago; could this be one of them?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

RE: Protecting flash drive in US-Mail?

The card worked i my brothers camera, as he was able to view the videos in that.
The card was shipped taped with Al tape to a piece of paper with description of the files.
I have received other SD cards from him that way without any problem.

I have tried three different SD card readers on two different laptops using two different OS. The card is simply not there! I have also tried it in two of my own cameras. Both say "Card Error". Not "Card Missing". One of the cameras did suggest a format, but I am not quite there, yet.

But as my brother does live in a high desert area of Arizona, the static electricity idea may have some value!

The lizard idea suggested by Comcokid appears to be less valid, even though my brother has plenty of the smaller cousins around.upsidedown
