I just formatted my HD204UI on firmware 1.08 as EXT2.
No problem with the formatting. Now copying files to it.
Though it works, I am just wondering that it being a 4k hard disk, is it efficient compared to the older 512b ones.
FWIW, the copying speed to the 323 was 23mb/s. From 323 to PC was 32mb/s.
Not bad I think.
