We tried to read the EFI partition data. That kills some devices if they also report the size wrong (eg the ipod mini). You'll probably find that with a custom kernel it matters whether you have EFI partitioning on or off. If so let me know - it needs a USB quirk entry.



OK, I'll be sure to try it both ways in the custom kernel.

In terms of your second statement, the camera did have a 2G microdrive on board at the time, so the line:
Nov 9 14:31:18 localhost kernel: SCSI device sda: 3999745 512-byte hdwr sectors (2048 MB)


is at least indicating the correct size. Of course, if the sector size wasn't 512 bytes, then there could be problems.. :) To be honest, I have no clue what the camera sets the sector size to be.

Thanks for the quick insight.
