The USB bridge chip is limited to LBA adressing, so you can't go past 137 GB
on the drive, from that end.
Rockbox theoretically could do BigLBA addressing and not be affected. Just
fantasizing: If you still want to go with this old hardware, you could atm
build a maximum system with with two 500 GB disks. If you don't want to swap
the disks out for refilling, one of them would have a <137 GB "interface
partition" in the lower part. You can then fill this partition, and let the
Rockbox Norton Commander plugin (tm) move the content to the other
partitions. Hey, this would be fun to wait for!
