Fake micro SD cards

The Market is flooded with fake microSD cards, especially on Ebay, these card mount OK, report correct capacity written on the package, and never report an error when capacity of the original card before modification has passed,  These cards even format OK to the fake capacity.  Here is an example,  a card  physically is 4GB but its label and FAT file has changed to say 64GB.  You never know it is fake except to find out after 4GB in this case is reached and files start not to exit even when the FAT file tells you your file is in the memory. H2testw software  is very slow, but you can  test your card by writing a lot of large files like videos to the card and find out is it really is what claims to be.  Also note older devices don’t read exfat formated cards, so read the specs of your device may be SD card is not the problem. Buy  SD cards from large chains or authorized dealers, consider  the rest fake. Use your PC to Test the card immediately after purchase because you might pass the window to return it.

I bought a fake Sandisk 64GB from Ebay, it was only 4B, he seller returned my money immediately and did not even asked to send card back. I read we can report incidents like these Sandisk to start an investion, but I don’t know Sandisk cares or not, please let me know thanks…

I put this post up originally (ages ago) because my wife had problems with two cards that she’ d purchased in the Philippines; they were not bought on eBay, but through a retailer. These cards subsequently proved to be fake. We were unable to retrieve any of the images on these 2 Gb cards even after sending them to SanDisk themselves, who offer a recovery service.

As stated above. The cards read correctly as the stated size, could be mounted and formatted. However, once they had reached capacity they would no longer function; the images could not be read at all. Effectively the cards become unmounable.

I think I am late to the party, did some reseacch on the net to find out this been going on for a long time. These fake cards drive you crazy because they don’t give you a clue what is happening. I also found out Ebay does not really care what these scammers are doing, and challenging these seller is a big hassle that does not go anywhere, the best we can do make this problem as public as we can. I bought Samsung Evo class 10 card from Walmart so far it functioning perfectly and super fast.

I’d recommend 7DayShop.com. They are safe and very reliable. I’ve been using them since the film days.

I did checked  7dayshop.com, holly sh*t, they are Brits, unreal prices $98 for 64GB class 3 , here a class 10,   64GB  sells for $60 form the best retailer in US, where this is only place professionals trust, no I don’t work for them:smileyvery-happy: I think the VAT tax really works over there,

Hi all

I recently purcased a Sandisk Extreme Pro 280MB/s SD Card from a reputable Sandisk Reseller & got the following results using H2testw v1.4:

Warning: Only 60317 of 60318 MByte tested.

Test finished without errors.

Writing speed: 34.1 MByte/s

Reading speed: 35.9 MByte/s

Am I getting my MB/s & MByte/s symbols mixed up?

The reason I tested is because I used it in my BMPCC & got drop frames.

Thanks

Pete

Very helpful. However, not that much use after you’ve already bought them. The cards that my wife bought and used initially checked out fine. She took many images until the card was full. All the images previewed before and after; it wasn’t until she removed the card from the camera and later reinserted them that she noticed the fault - by then it was too late and she could no longer which shop she’d bought them from (in the Philippines). Anyway, thanks for the tip. ???

Although this is an older post, no one has answered this question.  Pete, that looks correct.  There are 8 bits in 1 byte.  so there are 8Mb/s to 1MByte/s.  Megabit is usually written Mb/s and megabyte MB/s.  Notice the capitalization for MegaByte.  So if you multiplied your writing speed and reading speed, you get the following in megabits 272.8Mb/s and 287.2Mb/s respectively.  I’m not sure if your card advertised Mb/s or MB/s.  Those would be big differences, although I know very few cards that can read/write at 280MB/s unless you pay through the nose for high end professional ones.  I’ve checked the benchmarks of Sandisk Extreme series and they go between 20MB/s to 80MB/s for high end ones.  So I think your card is spot on.

I found this forum after purchasing a counterfeit Kingston card off of a Chinese shop in Quito, Ecuador and wanting to learn more about this dark side of the market.  The card is advertised 4GB and has only 481MB usable space shown after doing the H2testw.

Cheers,

Woah! Learnt something from this post. Didn’t knew that people are selling out fake cards too… 

Hello. Nice perfect fraud here. EBay specisl.
Can I upload pics?

I too got lured into buying a fake micro-sd card for my new phone. The capacity was 64 GB but was showing 67 GB in the system. I had to return the item and ask for a full refund which I got thankfully. I have documented everything on

The problem may be that it’s a USH-II card. The BMPCC only has a UHS-I reader, and perhaps whatever device you’re using to test the card is the same in that respect. This can cause dropped frames and speed issues, even when the card appears as it should to the device. I discovered this after buying a Lexar card that was UHS-II. You need to check Blackmagic’s list of approved cards, here: https://www.blackmagicdesign.com/support/faq/43083

i have one question “Sir” i ran the test too on a 32 gb micro sd card it runs upto 12 ,324 megabyte for 2 hr because i am getting 1 MB/s speed of writing on card and then it failed because my card is diconnect from computer which was connected using a card reader and italso verify  that it has no error in 12324  i ran the test utility h2testw 1_4  i have sandisk micro sd sdhc class 10 ultra  32 gb card

I agreed with SandDisk Guru “drlucky” You have to buy micro SD card to an authorized dealers in your area. Keep in mind that every SD Card has microcontroller that can be programmed so must have to know SD specs before buy another one.

SDSC or SD: up to 4GB

SDHC: upto 4GB - 32GB

SDXC: upto 64GB - 2TB

Hi everyone, I have a case where I have just purchased SanDisk 200Gb microSD on ebay UK website, paid 50EUR for it so thought being reasonable enough offer espeically from a UK seller, took my chances and here it goes I have a fake one. Genuine seem like package, but memory card has no lump at the back side and the top side where fonts are printed contain like gloss-spray paint like discoloration an some imperfections on the top, however, after reaching out to seller about the refund, he wants this counterfeit returned to him which I am not going to do obviously as this would mean letting go of a hard evidence. I am uploading video fottage evidence on youtube for PayPal and eBay and will attempt to seek justice having ebay to refund this case and investigate the seller trough greater means, but what can I do really, should I or is there a way to report this case to SanDisk UK official so legal case can be built against such fraudulent individuals? I have all seller details such as name and address on file.

Just venting, and maybe looking for good advice/input from SanDisk team member on here.

Thanks
