Unfortunately most of you will read this page after buying counterfeited CF cards, but hopefully my story will help you find the truth about what you bought. And maybe even prevent you from clicking the wrong 'buy now!' The first thing to realize is that no one is safe. Obviously buying from Ebay is not the brightest idea, but major (online) stores are also selling fake Sandisk cards; don't think it only happen to others. Anyway, here's what happened to me. I bought four 16GB, 60MB/s Sandisk CF cards from Amazon Japan in November 2012.

The order was 'fulfilled by Amazon', which means that the goods are stored and shipped from an Amazon warehouse. However, the shop actually owning the cards was not Amazon.

They seemed a bit slow, so I benchmarked them by dumping 2GB chunks of data using the unix command 'dd' (*). Alarm bells started to ring when the new 60MB/s cards turned out to be slower than my older Extreme IV 45MB/s card. By that time I had also noticed two subtle differences between the 4 cards, even though all boxes were the same: • one had a completely different serial number. It showed space for 308 shots when formatted in my camera, while the others showed 301 shots. So it was not only cosmetically but also physically different.

• the labels were of slightly varying quality. Originally I though that meant different batches, which is rather good (**). But it was a bit more than that.

The shit really hit the fan when I tried to benchmark the 'odd serial number' card: no data could be written on it from the desktop, although the camera was happy to put pictures on it. Typing the 'odd' CF card serial in Google led me to a page explaining exactly the problem that I had: this serial number is from a Kensington part! Now I was clearly in couterfeited items territory, so I promptly followed Amazon's procedures to return the items. More on that later.

So here we are finally: how can you spot a fake Sandisk CompactFlash card? Obviously there are no rules, only a few hint. Actually quite a few hints if you pay attention to details. Package The real and fake boxes are quite different, but this is probably due to Sandisk renewing their design. Luckily, the devil's in the details: Counterfeited Real • The CF card shown on top of the camera image (box front) looks crudely photoshopped. This is the case for both fake and real packages! Also, both packages show the proper rounded metal corners for the card (see below) • The 'CompactFlash' on the CF card picture does not have the trademark sign (r) on the fake box.
