There are many fake capacity USB flash drives on the market that claim a particular capacity, but only delivery somewhat less than this (particularly the larger drives). This is sometimes refered to as fake ‘oversize capacity’. The counterfeit drives we have examined appear to have the stated capacity in Windows Properties and it is not until you test the drive with these software that you see that there is significantly less real space.

There is also a similar problem of low quality drives (which may or may not also be counterfeit). These drives might have the capacity they state on the box, but be of such low quality that they corrupt files or lose data stored on them due to bad sector. While many stores, such as Ebay and other online auctions, provide information on how to detect some of these fake USB flash drives, they generally rely on physical markings on the drive, such as incorrect serial numbers or typing mistakes on the packaging. Of course this only works for well known documented cases of counterfeit SSD drives, Flash Drive, SD Cards and etc.

To avoid being cheated, ask the seller to run through their Flash Drive with one of these software and have the report emailed back to you. This will be a legal document in the event that he or she willingly sold you a fake product that doesn’t match the description.
