No, wear-leveling (done at the memory controller level) will dynamically re-map addresses on the actual flash chip to ensure a relatively consistent number of write cycles across the entire drive. The only way to completely "wipe" a flash disk is with a hammer.
Yes, but what if I overwrite the device with random data from the very first to the very last byte? Suppose the size of the device hasn't decreased I'd think that wear-levelling has no chance to spare blocks in this case. kind regards Stefan -- make -it ./work GnuPG-Key: B96CF8D2 <sw () tanis toppoint de> Fingerprint: D8AC D5E7 6865 19B1 385F 8850 2AB7 6A82 B96C F8D2 _______________________________________________ Full-Disclosure - We believe in it.
