Disk Scrubbing Research and Suggestions
Just getting a feel what other organizations out there do with disk scrubbing...
- What do you use to scrub your decommissioned disks? format/analyze commands? dd? 3rd party tools?
- Do you do anything different between internal disks, disks in an array or SAN attached storage?
- How many times do you scrub them? 1? 3? 7? 10?
- Do you separate/care what was contained on the disk and base how to scrub them?
- What do you do with other flavors of Unix and even windows servers?
Just getting ideas and recommendations from the community while doing more research.
Thanks
Dave

This will work and take a long time.

Most of the programs will run patterns at least 4 times.
For disks that are not accessible you can only degauss them and crush them.

We physically destroy them since we don't have any disks that are worth any amount of cash on Ebay that justify the hours and hours of scrubbing time. If the disk is worth anything at all we can find an internal use for it.
You can smash them with a hammer yourself (fun!) or use a more "official" method. You can even buy shredders that will actually shred your entrie disk drive into whatever size pieces your spec requires:
