Can government recover erased HDD data?

root said:
a format will only rease the first bit of each sector...

to truely erase a disk you have to do what is called scrubbing, (where every bit is written and re-written)...

even then some reminance of the residue will be left and is readable (to specialist labs)

five pass scrubbing is the standard for saying that the disk is unreadable.

i see thanks
