I use Eraser to securely remove data from my hard drive. I've gotten in the habit of basically using Eraser anytime I delete files. Does this wear down my hard drive each time I use it since it's wiping over the data several times? I usually use the 3-pass DoD option. Also, in the options of the program, I usually have it set to clear the paging file at shutdown, however when I look at it now, the box is not checked and the option is grayed out so I cannot select it. Any ideas why? Thanks!
