How to spot a fake or counterfeit Olympus XD Flash card : eBay Guides

While this guide is specifically for Olympus XD cards,
it is applicable to any manufacture or type of flash card.



Here are pictures of three XD memory cards.
The first picture is of a counterfeit Olympus XD card I recently purchased
.

No unique serial number or manufacturer on the card,
and the label is dull and poorly printed.

The above are counterfeit cards.




Unique serial number with manufacturer's name on a legitimate 32MB card


Unique serial number with manufacturer's name on a  legitimate 512MB card


The second and third pictures are of Olympus XD cards I purchased from authorized dealers of Olympus products.

According to Olympus, all their memory cards have a unique serial number printed on their memory cards.
All their memory cards also show the manufacturer of the card.
In most cases, fake or counterfeit cards have poor quality silkscreened labels,
while the authentic Olympus XD memory cards will have crisp, clear, bright and shiny labels.

If your card does not have a unique serial number and manufacturer label on the flash card,
it is a counterfeit/fake.

The only addition I would add to the above guide is on testing your USB drive/memory card.

To test a USB drive/memory card, uses QuickPar or QuickSFV to create checksums for files large enough to fill the capacity of your USB drive/memory card.

Copy the files to your USB drive/memory card, and then copy them back to your hard drive,
and then run QuickPar or QuickSFV to verify the checksum.
