Use this slider to specify how you want the free space erased:
A
This option writes over the free space once. This is the quickest option, but it provides
the least security.
B
This option writes over the free space three times. The erasure takes three times as
long, but it gives you a medium level of security.
C
This option writes over the free space seven times. This takes the longest, but gives
the highest security.
