There is no "depth" and no "history" to be recovered, there is no "half charged" or "half magnetic" state. If hardware was able to "read history" out of the storage you would be facing regular corruption of your file system because it would accidently happen all the time.

Data is written in bytes in hexadecimal characters and your talking bits. Expensive and sophisticated analysis of removed disk can recover erased data using edges of write track where weak image remains unless erased about 7 times.

Thus my joking reference to the Feds that recommend repeated wipes for security of secret information. How can you store 1 Byte of data on a storage device that only has two states? Each tiny storage unit is an oriented magnetic field "north-south" or "south-north" which represent the bits "1" and "0".

Edited by technonymous, 22 December - Virginia, USA Local time: Edited by technonymous, 23 December - Posted 25 December - Most programs which have the ability to wipe write over with junk then delete the junk to clear the space again free space on your disk will offer doing up to 7 rounds of wiping, that level of wiping is quite unneccessary, in the end if you wipe once and then go on using the computer as normal it is almost impossible for anything large enough to be of interest to anyone to survive.

Back on this site, for a while anyway, been so busy the last year. Cheese Head Land Local time: When this happens the data written gets slightly moved though the movement is very very small as the "space" between tracks has become smaller and smaller these days from "true".

This means that data previously written may still be there the analogy would be the infamous 18 minute gap in one of the Nixon tapes and the data "could be" reconstructed as was done from the original Dict-A-Phone spool in the Nixon recording.
