RE: DISK Sanitizer Help

Where are you getting this information? Please cite research that proves this. We are talking about stuff that has only been finalized in 2009 via the OPAL group. Are you thinking of bitlocker or some other software based solution?

Self encrypting drives are completely different.

Speaking strictly from a security practicality perspective:

In the future, when you replace these disks you may want to opt for the new self-encrypting disk drives. It makes these discussions of disk wiping a thing of the past.

Instead you simple change the drive encryption key before handing them in for warranty replacement or for sale and all data on the drive is rendered useless.

These have been proven to be pretty vulnerable, at least PC oriented ones. I don't know if there are IBM i specific ones.

Rogers,

If management is dead set on re-selling these used disks, then Rob's option would be the path of least resistance. However, as a fellow "banker" I would not recommend you attempt to wholesale the disks. The cheaper option in my case would be to destroy the disk and refurbish the system and I/O. When you factor in the opportunity costs of your time, plus cost of Disk Sanitizer, plus the time and cost of all the CYA paperwork, plus the perceived risk of selling disk that once contained restricted company data.....it's just not worth it. (Note: I said perceived risk, not actual risk.) Those of you who deal with auditors should understand my point.

If I had to guess that 2.5TB is comprised of 140GB drives which works out to about 20 or so disk units. Used market price per unit would be about $300-500, meaning the most you could expect from a reseller would be $200 per unit. All that said....if management asked me to do this I would turn around and ask them if all that trouble and perceived risk was worth $4000-5000?

Maybe not for you but for me and hopefully the OP, the disk wiping is a sunk cost. The alternative to dealing with the drives is putting them in storage where they will sit for a long time until everyone forgets what they are. Then they will get sold without being wiped. If you're being responsible the disks must be wiped no matter what the outcome.
I've acquired many systems of all sorts where the original owner held onto it for a long time to avoid cleaning the system and eventually they got rid of the system through some other means anyway. Either through termination of employees who know the risks or office moves or something else. The best bet is to always deal with the risk sooner than later.

Thanks,
Mark
