Since typically counterfeit cards come in cheap packaging, this really helps make the card look genuine. This is a knockoff product that came in what appeared to be genuine Samsung packaging, meaning either the packaging was smuggled out of the warehouse where it was genuinely made for Samsung, or a skilled forger made it. Also, looking at the card itself, the paint-job is low quality, with blurry edges between colors, text that appears slightly off from official images of the product, and the plastic on the back is black when it should be white.

Indicators are that it fails to write/read properly, appears to overwrite the same sectors when filled beyond a certain point, intermittently fails to format, has hundreds of bad sectors fresh out of the package, and is classified as generic in its hard-coded memory. I am certain this is a counterfeit Samsung microSD card. I purchased it from a seller on eBay who had 18 100% positive feedback points, so didn't feel like there was a risk. It's supposed to be a 128GB Samsung EVO+ microSD card, but to my dismay and three days of research and testing, is definitely not what it seems. Everything from your description of the back side is the same except the third line of mine seems to be a different serial number: DHFH179GE640. I found your post here through a web search and wanted to comment that I got a card with the same code of 'MBMCDGVGOFGW-T' that yours has. I've used the same adapter and port for all testing. Note: the TS-RDF5 SD Transcend is the microSD to USB3 adapter I used for testing on my mac mini. I will update if it decides to quit working.įor comparison, here is the Thinkware branded 32GB microSD card: F770 said nothing about it, I did format within the F770. I inserted it this morning before driving to work and it seems to be working okay. I've been using a 32GB version for a while and it's been solid, so I decided to try the 128GB version. Upon insertion into the F770 it initially said to format card and then shortly went into the please restart loop. #1 - Toshiba Exceria M302 128GB microSD. I've recently tried a couple of other 128GB cards and here are the results.
