thc-secure-delete ( anybody installed it ? )

[R.L. Reingard]

Hi Lee
starting from scratch is not what i want to do right now.
embarassing, in never heard, that one could retrieve data UNDER data.
so far, i would be pleased if able to fully delete the free space.

dd if=/dev/zero of=~/myhugefile bs=1M count=`expr 1024 \* 5`

the whole command means counting bytes for blocks, and the digit '5' would  
be the 5GB i did mention before?
does this come to a stress point for the machine/system if this is the  
full space left on the disk, or is the system able to handle the work?

i curious for getting to know more, haha.
René
