ECF... and everyone else involved. I have relatively simple needs for my NAS, and I would just like to wholeheartedly thank you for posting this Firmware Update. I can confirm (at least on my Lion systems) that the repost of the 2.02b01 Firmware decompresses properly and after updating I can now write to the DNS-320 from my 10.7.1 systems. Thanks a bunch. Now on to further exploration of this device!
On an unrelated note, I did try iTunes 10.5.1 (latest version) and with this Firmware update (as with the previous Firmware version) the iTunes Server does not seem to work. In iTunes, I see the DNS-320, but when I select it and enter my password, I get the Loading progress bar at the top but nothing seems to load.
This is not to diminish IN ANY WAY my enthusiasm for 10.7 to now be working properly. Thanks!!
