Stockpile in a storage room “until we figure out what to do with them”
Degauss Physical destruction (aka “shredding”) Data erasure
Stockpile in a storage room “until we figure out what to do with them”
What is the cost of the storage space? Do you have an inventory with serial numbers of all
devices? If a drive goes missing would you know? If a drive is temporarily removed and copied would
you know? Who as has access to the room? When jobs change is that access revoked? Do you have a log of all entries to the room? Potentially valuable assets depreciate while sitting
there
Degauss
Costly equipment Periodic calibration required
No verification data really destroyed What training does the operator need? What kind of proof is produced that the drive was
actually degaussed At all Properly for that device
Can the drive be recycled after degaussing? Re-used? Only precious metals?
Do you only have magnetic drives? No SSD?
Physical Destruction
Expensive equipment Maintenance
Safety concerns to operators? Flash chips are really small
Are they destroyed? What do you do with the shredded pieces?
Can you really recycle shredded drive material? Offered as an on-site service
How expensive? How long must you stockpile drives?
Degaussing and Shredding
Different levels of green Same stockpile issues until processed Do you have an inventory with serial numbers of all
devices processed?
Data erasure
Processed drives have greatest recycle value and options
But What does it take to REALLY erase the data beyond
retrieval? What training is required? Cost of software? Associated equipment? What about different kinds of drives?
SSD RAID arrays Remapped sectors Hidden areas?
Different form factors ATA SATA SCSI Fibrechannel
Flash/non-volatile/solid state memory erasure
More complicated than HDD in terms of data erasure “overprovisioned,” memory capacity accessible only
by the SSD Hidden from host
Flash/non-volatile/solid state memory erasure
Tentative techniques Delete and format – problematic like HDDs Degaussing – unaffected Physical destruction
“The smallest package (BGAE63) is 10mm on a side. This means that particle sizes less than 10 mm will ensure that no flash packages remains intact. To be conservative, we recommend 75% of this value or 7.5mm.” - Destroying Flash Memory-Based Storage Devices, Steven Swanson
ATA’s Secure Erase – no standardized implementation
Flash/non-volatile/solid state memory erasure
Requirements Removal of BIOS
freeze locks Device specific
implementation OEM cooperation
Flash/non-volatile/solid state memory erasure

Data Erasure
Is data erasure an option? It’s all about
When you do the erasure The software
What’s the different between using something like DBAN for data erasure and just shredding the drive?
Process is largely the same Many of the risks are shared Just a different physical result Re-use issue
Enterprise data erasure is a whole new way of looking at things
Enterprise Comprehensive Physical Disk Management
Erase drives the moment they are decommissioned Eliminate need for specialized equipment Multiple form factor / connection technologies
Eliminate stockpiling Even temporary Erase the drive while it’s still connected
Enterprise Comprehensive Physical Disk Management
Reduce/eliminate human based processing and error Training
Eliminate human based record keeping Centralized, enterprise-wide documentation of every
drive and its serial number Commissioned date Decommissioned and erased date Certified
Trustworthy confirmation Automated process run software Serial number Accurate and granular down to the sector level
