Your flash memory card or USB flash media is fake? Restore original media size - only one click!
In recent years, the trend of cheating customers by unscrupulous Chinese sellers is gaining momentum with enormous speed.
Here is an example:
You buy 32 Gb Class 10 SD memory card (seller specification) at a very low price, which you can't even find anywhere else in Internet. Actually this price is good reason to think about nature of such cheap CD-card, but the seller is very polite to you, and the parcel has reached you unprecedented fast.
The card flaunts proud print "32 Gb Class 10".
You insert your card into your card reader and see that the card really has a capacity of 32Gb.
"Awesome!", you think...
It takes time and you notice that your card is actually not so fast as you expected...
It takes more time and the music which is written onto your card is "gurgling" and the video is "falling to pieces" or even neither music nor video is playable.
"I have my working documents and photos from birthday party", you think.
...But there is nothing you can return...
And here's the thing:
Such fake products is preparing on the manufacture. Manufacture take a slow (not necessary) SD-card of smaller capacity, 8 Gb for example. The controller of this card is flashed in such way so your reader sees 32 Gb. Then the appearance is given in the appropriate state.
As a result you don't buy your SD-card at a cheap promotional price, you actually buy cheap SD-card at very high price. Moreover you have a big problems with you data written on such card, because the fact that your computer and your phone see 32 Gb on this card doesn't mean anything. Any data that you write into this card above 8Gb limit will disappear into thin air.
Such a sad example.
But there are thousands, dozens of thousands of such cases. Even more...
