Don, I suggest that you look into your vendor's implementation of encryption of data at rest.
If you have HDS then all RAID schemes and disk types are supported (HDD, SSD and SATA) and there is no performance impact. I believe EMC and IBM also support Encryption of data at rest. With encryption of data at rest there is no exposure as you describe, and there';s no need to scrub/erase/degauss/destroy your disk drives when you replace them.

I can't seem to find anything definitive other than a lot of "data may be recoverable" statements from vendors selling secure erase services. Just curious if anybody has any hard data to demonstrate an exposure or not. ________________________________ Donald Grinsell State of Montana 406-444-2983 dgrins...@mt.gov<mailto:dgrins...@mt.gov> "Any fool can write code that a computer can understand.
