Disk wiping recommendations

[eculbert]

Resending an email from Nathan that he posted here almost 4 years ago. I used it on a few and afterwards, the system didn't even know any device was attached as I hadn't specified a starting block, it wiped block zero. It is the 'w' that writes. Without the w, it just verifies the blocks.

If the hard drive still works, boot knoppix on the machine, then run
'badblocks -svvw /dev/hda1' or whatever the drive is. That will zero
everything in the disk. I've not found a recovery utility yet that will find
anything after that.

web at arrl.org for questions and http://www.kb0mga.net/exams/
