Drivestation is formatted to NTFS.
I've a partition that the Ellion creates as you say for recording (UDF - don't know much about these) and the rest of the drive within the Ellion unit is partitioned to FAT32 for the purpose of transferring any recordings I want to retain.
I think the Ellion offered me a choice of a third partition (eg NTFS) when I originally formmated it via the menu on the unit but I just opted to format the entire remaining space to FAT32 for the purpose of the transfers. I might try copying the files off the Ellion and reformatting it.
