When I try to format a flash drive, pen drive or SD card, get the "disk is write protected" error message? Don't worry!

SEE: Media disposal policy (Tech Pro Research) Best practices for USB drives Six of the drives from the US could not be accessed. In total, 20 drives appear to have had no effort made to delete data, 19 of which were from the UK. The identity of the previous owner of the drives could be determined for 20% of drives from the US and 22% of drives from the UK. Some 68% of drives sourced from the US and 67% sourced in the UK still contained data from previous users, the report found. Researchers at the University of Hertfordshire purchased 200 used USB flash drives-half from the US, half from the UK-to determine how securely data on the drive was stored before being disposed of. USB drive users need to exercise caution when throwing away or recycling those devices, according to a Wednesday study from Comparitech.
