My D2X should be arriving this week and having 2 x 1GB Ultra2 will have some limitations, especially when shooting RAW. I guess I'm a bit confused about Fat16/Fat32 and D2X. I understand that 4GB Ultra2 has to be switched to Fat32 and later formatted to allow 4GB of space. What about 1GB Ultra2 ? There is no switch there, right ? When formatted in D70, 1GB Ultra2 will be in Fat16 ? When formatted in D2X, 1GB Ultra2 will be in Fat32 ? And I can keep formatting between two without any adverse reactions, right ? Now, what about some deals on 2GB Ultra2. I missed that 4GB Dell deal. I wish I purchased one. Thanks for all your help.
