However it is no solution on a Mac system and I think (hope) they are looking for a dual system solution.
This is true, but it would be a very big help on a Window system. Also, while I'm sure the goal is to keep the Windows and Mac versions of PM nearly identical, there will always be some slight differences due to the fact that the approaches these two operating systems take to some concepts are different. The fact that Windows refers to drives by letters while the Mac OS uses the volume labels is a perfect example of this.
I woludl also like an option of either auto removal of the downloaded drive.
There is an option to "Unmount Source Disk(s) after Ingest" (at least on version 4.5.3 for Windows).
Also the best would be to keep the cameras from renaming the cards upon format. But even Camerabits recommends to format in camera before each uses.
You could use the "Erase Source Disk(s) after Ingest" option, which will clear off all the files while leaving the volume name intact, rather than formating the card before every use. An occasional reformatting in camera followed by a re-assignment of the appropriate volume label in the computer can always be done if you still feel the need to do so.
