I looked at the logs for your support call. You didn't send in the entire unit - you removed the HDDs.
We either replace HDDs from an intact unit, or replace entire units, but we do not replace logic boards. We do not repair units on the logic board level.
Your RMA was set up for the whole unit.
If you wanted your data intact, you needed to request an advance replacement (IE, we send a unit to you, and you change out the HDDs). The phone support team left a message on your phone, 5-28-09, and are still waiting for your answer on this. Please return the phone call and let them know how you want to proceed.
