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.

Subject: RE: DISK Sanitizer Help
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?
