Fw: How long will this take?

I wipe a new drive for two reasons.

1) I like to make sure it's nice and clean which makes me comfortable. It bothers me if I don't.

2) I can make a reasonable determination about which sectors were used when setting up the partition table(s) and any boot loaders so I know which sectors were used and need to be backed up. Yes, I'm actually going to use dd to back up that space outside of any partition and store it elsewhere so I can restore it later if it is needed. I prefer to be safe rather than sorry. In today's cyberspace you just can't run without a backup. It's not a question of if you will be attacked, but when and how. I refuse to pay a ransom.

If you get a used drive and you are curious then sure, you could go snooping around. I remember when we used a VAX running VMS back in college. It would allocate some huge amount of disk space when compiling our C programs, even though it wasn't used or cleared. I found old deleted emails from other users in that slack space. Yes, they were in plain text. We later found an option to use when compiling our programs to prevent that so our programs didn't have to use as much space which was limited by a disk quota.

Because the police raiding my house for dealing drugs is not a
realistic threat. Looking at my drives for running Tor could be.
