Experiments in Data Wiping and Recovery
Experiments in recovering files… resulted in 70% recovery of a wiped USB drive.🙂
After chatting to someone about disk wiping and data recovery, I decided to try a few things myself. Primarily I wanted to know whether a storage device could be securely wiped using just native Linux OS features.
Before going further, I should mention that one method here will recover almost anything and everything, and I strongly recommend against practising on some random device that you bought from some guy in a pub – the last thing you want are nasty surprises.
Obviously it’s important to ensure we’re wiping the correct filesystem. With modern Linux distros, the /media directory contains pointers to the volumes’ actual mountpoints in /dev, and the latter must be determined using the $df command:
