If you are planning on buying a USB drive from eBay or any other popular online e-commerce site, chances are that in spite of those high seller ratings, you may still end up getting a counterfeit!
Popular USB drive makers like Kingston, Transcend and the like are much more likely to be duplicated.
And when the sole usage of your latest thumb drive is going to be that crucial back-up routine, it becomes vastly important that the drive itself is trust-worthy and pristine, lest it ends up as a double whammy!
It becomes even more difficult when the forged units sport nearly 100% original looking packaging. And bar-codes and serial numbers are something too complex for an end user to verify until the same are verifiable online @ the drive maker’s website.
Counterfeiting in USB drives involves hacking of a USB drive’s firmware (basically a low-level editing of the firmware) so that the drive’s specifications report a higher than actual capacity (of the physical NAND chip on board)
As a result, when you try to write data to the drive over and above its actual capacity, your data gets stored as corrupted.
Certain tools for testing out USB blanks are slowly becoming a sure shot, one step verification standard.
These can actually be used both for detecting the bogus USB as well as to check the actual / real world performance (i.e. capacity / operating speed and so on) and other advertised specifications.
Evaluating the above FAKE USB’s result, it is clear that a 4GB flash drive is masquerading as a 64 GB flash drive. Imagine the seller’s and the fake USB creator’s audacity!
Moreover, since a genuine 4GB drive should be about 3.9 GB after formatting (and not 3.8 GB), the difference indicates that some sectors are obviously not usable and have been marked as bad. This further indicates a low quality NAND chip.
So once you start using the drive beyond 3.8 GB capacity, the data will surely be unrecoverable.
Help! I actually have a fake drive? Now what?
If your test results indicate a fake USB at your hands, you can approach the seller on eBay (or your e-commerce site) and tell him the situation. Thanks to H2testw 1.4, you have the required proof too to back-up your claims.
Most sellers would be quite forthcoming in helping you get a replacement or a refund. But in case of issues, you can always post comments on the e-commerce site with a copy of this report.
Following which, any self-respecting seller should be willing to help you, as the reputations are what eventually would get them their business.
Hope the above article helps you to keep counterfeit USB's at bay!
