ReadyNas Ultra 4 boots to certain % and stops further booting

Hi all,

I could be that this question was already raised before, howver I didn't find the proper solution for this.

Suddenly when I booted my Netgear Nas it would hang on a radom percentage when it was booting.

If I reboot the number would be a other percentage where it will get stuck on again.

The following things I've tried didn't helped:

- Removing one disk and try rebooting it.

- Check if the memory is still good inplace etc.

- numerous of atemps rebooting.

Note that the ready nas is not running the original Radiator OS but the Readynas OS 6.X.X

Does anybody have a proper solution for this or know what to do?

PS: I don't want to lose my data otherwise I would already tried a Factory Reset.

Your advise is more than welcome :)
