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 sectors. There is also a similar problem of low quality drives (which may or may not also be counterfeit). 😭 😍 😂 6 Freeware To Check And Repair Hard Disk Bad Sectors 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.

This is sometimes referred to as fake ‘oversize capacity’. There are many fake capacity USB flash drives on the market that claim a particular capacity, but only deliver somewhat less than this (particularly the larger drives).
