It's not a custom file system. It's linux native ext3. The file systems are being created in such a standard linux way as to even leave the lost+found directories on the partition.
2 partitions created by the 622. 1 is 1GB and the other is the rest of the drive. Lots of speculating here, and until I get my drive enclosure I won't be able to test it myself, but others are looking at it. My guess is that the first (small) partition is going to hold the bits that tell the drive what receiver formatted it and all that "secret" stuff. The larger partition will have a folder where transferred recordings will go.
Will you be able to take a movie from external drive 1 and copy it over to external drive 2? I have no idea. My guess (again speculation at this point) would be "no" as the contents of the folder holding the recordings may have to match some kind of index in the 1GB partition. Makes sense if they are trying to ensure that the recordings can only exist in one place that they'd put lots of checks and balances into this.
I'm going to stomp around in the filesystem when I get my enclosure. More out of curiosity than anything else. I don't want to break this because I want it to work and I want them to continue to develop it and add new features. My guess (more speculation?) is that they've had some pretty high level unix weenies work this up to the point where it's pretty bullet proof.
But I was always the first kid on the block to show up with a screwdriver whenever anybody came home with a new toy. I just like to know how things work.
