All,

I have uploaded a proposal to protect partially encrypted volumes.  This addresses a concern about how tapes encrypted by an encryption aware application or system can be protected when the tape is moved to a different drive and an append attempted.  Most customers are wanting guarantees that once a volume has had encrypted data placed on it that all subsequent data is also encrypted.  There may also be some installations that desire the ability to have mixed encrypted and clear text.  This calls for care in how we meet both these requirements.

This proposal has not met the two-week rule, but if possible I would like to be able to get some feedback so I can make changes and have a good chance of getting it approved in Sept.
