How to Identify a Fake Samsung Micro SD Memory Card





Introduction: How to Identify a Fake Samsung Micro SD Memory Card

About: I've been creating YouTube video for around 2 years now and love being able to bring my knowledge to the people who need it most. With my broad range of interests, I find I like to figure out Technology and ...

Fake memory cards are out there and identifying one is sometimes hard. I recently got burnt, but managed to chronicle how I knew the card was a fake. Follow there step by step instructions to determine if your Samsung Micro SD Card is a fake or not.

Step 1: Complimentary Video

To go along with this Instrucatable, I've also shot a video that you can watch and experience first hand.

Let's get started!

Step 2: Check the SD Card Adaptor

Before even opening the Samsung Micro SD Card packaging, have a look at the SD Card Adaptor. Pay close attention to the printing of the words. Check to see there is not misprinting as this is a quality control issue that wouldn't escape a real Samsung Micro SD Card Adaptor. If it text also doesn't have really sharp crisp edges, then you may be looking at a fake.

Step 3: Check the Hole Punch on the Packaging

Generally, every Samsung Micro SD Memory Card that I have purchased had the hole punched out of the top of the packaging. If your doesn't, then this could be another sign that the memory card is fake. It's not a complete positive, but it does lean more towards the side of being a Fake Samsung Micro SD Card.

Step 4: Check the Samsung Micro SD Card Quality

On closer observation, the edges of the Fake Samsung Micro SD Card was black. On all official Samsung Micro SD Card, the plastic edging is white. When they manufacture the fake micro sd cards, the costs involved to have the edges white is too expensive, so this is another giveaway. Black edges on a Samsung Micro SD Card always means it's a fake. Also check the text sharpness on the face of the micro sd card. If this is not sharp or a little bit off, you can guarantee that it would not have passed Samsung's quality control.

Step 5: Check You Model Code on the Back of the Packaging

If you have a look at the bottom right hand side of the packaging, you will notice a Model Code.

Something like MB-MG32EA/EU or MB-MF32DA/AM or MB-MS32D/CN

The /EU means the product is meant for sale in Europe and Australia.

The /AM means the product is meant for sale in America.

The /CN means this product is meant for sale in China.

If you don't live in China and you receive a Samsung Micro SD Card with the model code ending in CN then you could be a victim of a fake micro sd card.

Step 6: Check the Made in Statement on the Back of the Packaging

On the bottom left hand side of the packaging is the statement of where the product was made. Official Samsung Micro SD Cards are generally Made In Philippines and will also be followed by:

Adapter made in China and guaranteed for 1 year

The fake memory card I received was Made In Korea and did not have the adapter warranty line.

Step 7: Testing the Samsung Micro SD Card on the Computer

Download the H2TestW software to check if the capacity of the Micro SD Card is correct. The 32GB Micro SD Card I got failed after testing 16GB. Counterfieters are able to modify the cards reported storage so it may appear on the computer to be 32GB but once it's tested with H2TestW, the results clearly show it is only 16GB.

Step 8: Conclusion

When you are buying cheap memory cards, just stop and think that maybe there's a reason it is so cheap.

Informative, but incorrect. First off, the edges of the edges of a true Samsung SD card are not always white. In fact, I still have yet to see a white edged card. Of course, I'm not paying attention to that detail either. Note the picture of my 128gb card... I bought this card from Walmart in the edge. And secondly, the incorrect size listed when you insert it into the computer may be a simple formatting error. In Windows computer, using diskpart to clean the card and then storage manager to format the card will typically take care of this issue. As far as the packaging is concerned, the punch out doesn't substantiate anything really, and therefore shouldn't be misconstrued as a sign of counterfeit. Also, the region code you refer to doesn't amount to anything either. That's just the market it was intended to be sold in...think of it like a car... A Volkswagen built in Texas doesn't HAVE to be sold there.

Don't instructables say We have a be nice policy and Please be positive and constructive? You come over as defensive of your purchase, however I'd be looking more closely at it.

Use the information given as guidance as the author says - indication not definitely- of being fake cards. Also ALL of my Samsung cards have white edges. If yours isn't white I'd recommend doing full testing using some of the freely available software test programs, I wouldn't feel comfortable* about that card. The 128 sees to printed in a heavier font (like bold rather than normal) than genuine Samsung cards- look at google images and you'll see that the font isn't bold.

*Note that I did not say that your card is fake, but that I feel that it would warrant further testing if I owned one like it. I hope it is not fake but it is better to be sure rather than lose data at some future point.

Firstly, in regards to the edges of a True Samsung Micro SD Card, why would Samsung go to the trouble of creating advertising with White Edges if they were going to create cards with black edges?

I know that the White Edges are actually a counterfeit measure used by Samsung. This is because it is easier and cheaper for a counterfeiter to use black plastic. Your particular card may be an off chance "Black" version, but like your one micro sd with black edges, I have 10 with white edges.

I've purchased different models of Samsung Micro SD Cards from a range of different countries to check the differences. All had white edges.

Secondly, it's not the reported size that's the issue, the issue is the verification process in H2TestW. Counterfeit card makers will often "tweak" the inner workings of the cards to report a different size. In my case a 32GB card was actually only a 16GB card. When H2TestW tried to write past the 16GB of actual space, that's why the error was reported.

Thirdly, I am a purchaser of a lot of technology products and gadgets for myself and the businesses I work with. When you see something odd like a hole punch not removed for the first time, it stands out. Every other Samsung Memory Card that I have ordered for a wide range of people have had the hole punch removed. Amazon, ebay, computer shops etc. If it stands out, it's worth noting.

And lastly, the volkswagen is made in Germany. Samsung Micro SD Cards are made for specific regions. Authorised sellers will have products for their designated region. That is why Samsung have region coding on the back of their Memory Card packaging. To identify the origin of the product.

This isn't an attack on your comments as they are questioning the methods I have listed. And questioning anything is the best thing when wanting to find the truth. If you find one thing wrong out of all of these steps, then you may not have a fake. If you find 2-3 or more, then I would guarantee that it's a fake. Like you said, if it's hole punch isn't removed but everything else gets a tick, then it's more than likely not a fake.

Thanks for your feedback too :)

Sd insight app will tell you whether genuine or fake. If logo appears, means genuine. If instead of logo, says invalid or unknown, means fake.

Thank you for this helped me avoid a fake, but I had a friend who purchased a fake. I noticed the SD Card adapter on the back did not say sumsung it was blank. In the real thing it says Samsung, also on the package said made in Korea but on the Micro SD Card it said made in Taiwan. Hope this helps.

Good stuff! Additional notes:

- on Mac and Linux you can use F3 (

- sometimes fake cards are NOT cheap

- can make it really hard to prove that you received a fake card

On a side note, virtually everything available for sale is counterfeited these days. I wanted to buy a good friend a Yeti brand coffee mug on Amazon. It was disheartening the amount of reviewers who had purchased one and found it to be a really cheap knock-off. So I bought directly from the manufacturer's web site. Shame on Amazon and other sites for not doing a better job of policing these counterfeiters!

Please would you add clear titles to your pictures to show which is a fake card and which is real ? Many thanks !

I think I've got a fake one, it stopped working after a few months

About Volkswagen, most of them are made out of Germany, in european countries or not. They've got factories in the whole world, in Asia, both americas and middle east countries. In fact, only the top ranges are finished, not totally built, in Germany.

To Sokamiwohali : Buying at Wallmart doesn't protect you against fakes.

How does Samsung communicates about copies of their products ?

if it explodes.. it's made by Samsung.

PS- Nice instructable.
