I have a live USB with Puppy Slacko 5.6 PAE
I want to use it to securely remove data from the hard drive of my old computer
Are there any builtin tools that I can use (besides just formatting the drive)?
Or are there any pets that I can download and then install into this live USB?
It has 1 HDD with two partitions (I think) which show up as C and D drives on windows
C drive has Windows and data while D drive just has data

See posts #228 & #229 on page-10 of my Puppy-Linux thread at the PC-Guide forums.

To write random patterns to a partition, you must first delete all of the contents of the partition, and then use the script to write patterns to the [so called, or designated as] "EMPTY" space.

For the record, Sylvander's post in that other forum uses the program from this post from 2007 in our forum. Smile

Here's what I saved in my "Commands" text file:
To write [default=5] random patterns of 0's & 1's to the free space on a specified partition or drive:
To see what it does and how, look inside the "wipe" program file located in /

/wipe -z /mnt/sdb1

sdb1 can be changed to whatever is appropriate.

I have several oldish but still usable hard disk drives lying around. I can't wait to try this on them.
