I purchased a NII 80gb on the current sale. It has worked fine now for about 5 months, but now will no longer power down.
It also is having problems interfacing with the computer - will not connect via USB 2.0 with the player connected - only if plugged in as a backpack alone.
I can sync with usb 1, but that is too slow as the main purpose for this recorder is recording 44.1K wav - large files. I am a sound tech, and use this device on a regular basis for quick or backup recording - or whenever I can't bring a full fledged 24 track PC recording system.
I did a firmware update to no avail. If I am correct this issue started once when I left the player on pause for several hours and the batteries ran dead in the process.
Anyone know what is happening here or how to fix it?
You might try to reformat the NAND. I had a similar problem earlier this week. My unit would not shut down. Reformatting the NAND fixed the problem for me.
This link tells you to reformat the HD too. I did not do that. If you do that you will lose all of your data, which you may or may not care about. Good luck
