Well, this is not exactly news. I have been using "large" USB drives for a few years now, and DFSEE has always made them work.
I use:
Lexar 64 GB
2x Kingston Data Traveler 64 GB
2x Lexar 16 GB
I also have a Vivitar SD card reader, which works fine with an 8GB, and 16GB, micro SD card, in an SD HC adapter (comes with them). The name on them is Core Micro.
FWIW, I always use DFSEE to properly set up USB devices (including USB hard disk drives), even my old 32 MB SD card is set up using DFSEE.
If I want to share the device with windows and eCS, it gets formatted as FAT32 (using DFSEE, but it can be done with windows too). If I only want it for windows, I use windows to format it as NTFS (but the DFSEE LVM info remains). If I only want it for eCS, I format it as JFS. I also have a couple of USB hard disk drives, that have two partitions on them. One is NTFS (for windows), and the other is JFS (for eCS). One of those disks is 1 TB, and the other is 250 GB.
