Be very careful handling your camera memory cards!
We just attempted recovery on another dead CF card with no success. It is most likely the culprit was a static electricity discharge. The smallest amount of static electricity (that you cannot even feel) can destroy storage cards and computer memory in a heartbeat. The damage may not show up for weeks or months – or may be immediately apparent.
Memory circuits are comprised of very sensitive storage material which is highly susceptible to static electricity. Consider this: The smallest static discharge that you can actually feel is at least 1,000 (one thousand) volts. The variety where you hear a SNAP and it makes your eyes water is probably somewhere in the neighborhood of 10,000 volts.
It takes a lot less than that to fry your irreplaceable data.
How to you protect your memory devices?
Here’s what I do:
When removing the memory from a DSLR (or any other camera), keep the skin of one hand or arm (or your foot if this is easier) against something connected to “ground”.
Likewise when inserting the memory card into the reader that’s connected to your computer, keep yourself grounded.
Where can you find a good ground?
The metal cabinet of any large appliance is usually grounded as is the cabinet of your computer (hopefully). This is not necessarily true of laptops. Most pieces of electronics with a 3-prong plug will have the chassis connected to ground as well.
If you have a non-carpeted floor, any metal cabinet sitting on it, like a desk or filing cabinet should discharge the static electricity on your body effectively.
You can purchase an anti-static mat if you handle sensitive electronics frequently. This is how we work on computers in the field. It’s a lot less expensive than data recovery.
