Did you use any other external HDD with your notebook?
I think there is possibility of power. I suggest try to connect Macbook to ND2300 with included AC power adapter.

I did use the supplied AC power adaptor but make no different. Did you test the HDD with MAC machine.

Any chance of a reply? Just tell me if it does not work. I just have to trash the HDD and buy another one from someone who cares about their customers.

1. Check your Mac Book connected AC Adapter
2. It may be related in F/W. What is your F/W version

Checked the AC adaptor. This is not a power related problem. I donwloaded the latest firmware 1.22 from the site but STILL no lucky. I checked the HD supplied, it is a Hitachi TravelStar 160G. I tried a 80G version from Hitachi as well. Same problem. However if I connect the HD with another USB enclosure (from another make), the MAC recognise the HD (same HD) with no problem.

In case you ask, I did a FORMAT HD using the feature in my ND2300 but this DOES NOT help.

I agree with you that this is a FW issue, please check this out using a MACBOOK (I checked this with my colleague who has the same MACBOOK, same results) and you will find the problem very quickly. Once it is fixed, I sure you can tell all the MAC user that I had the problem and it is now fixed with FW xxx. I dont mind to be your reference customer... If you can fix the problem of course.

We tested Nexto-OTG is working with MAC OS 10.4.
What is your OS version?
It can be compatibility issue according to the MAC OS version.
Check if Nexto-OTG is working at OS9.2

Also check what you see at [System profiler]->[Hardware]->[USB].
Can you see USB2.0 storage at there?

Also change your USB cable to the one provided with Nexto-OTG.
MAC Book may have many USB ports. Are you tested at all those USB ports?

I have a MacBook OS X 10.4 Tiger and the NEXTO ND 2300 with 160Gb Hitachi HDD. The same happens here after the latest security update from Apple; I can't access the NEXTO anymore. In system profiler I do see a USB2.0 storage.

Anyone knows how to fix this? This is not fun, my holiday pictures are on the nexto and I can't access them.
