is it possible to recover data from a fully formatted flash memory based pen/thumb drive?

Question

actually i believe that if we set/reset the memory cells of a flash memory unit to all 0s or 1s, then it should not be possible to recover data from it since there should be no 'leftover' information anywhere- as all the information that is stored anywhere is in the state of flip flops which can be either 0 or 1

Answer 1

yes its possible

Answer 2

If the drive is repeatedly written over with zeroes and random data, then at some point it will be impossible for anyone to recover the original data.

Even after one write-over the process is probably difficult and complicated.

Do note though that a normal format does not actually erase the data at all, it just sets the file allocation tables on the start of the drive to show the drive as empty.

Answer 3

It is possible. Formatting simply unlink the data from the directory system. Setting all units to all 0s and 1s is one mean of overwriting the original data with garbage. Random overwriting itself takes months to achieve the best data deletion. Yet data remanence, the physical representation of the data, can still allow data to be recovered in pieces. Destruction of the pen drive is the only way for complete eradication of data.
