I have a 2TB Terastation Pro that will not now startup correctly. The unit has been in service for 4 years and has always been reliable upto now. The issue started when I tried to add a new user via the web access pages. The unit allowed me to login but then as soon as I tried to access any of the settings pages it asked me to login again. This cycle continued and I could not change any settings. At this stage file sharing was still working.
I then decided to reboot the unit to see if this would sort out the issue. The unit starts up as far as the "System Now Rebooting........." message and then just hangs with only the Link/ACT LED flashing. I then decided to remove the HDDs one by one to see if there could be a fault with a hard disk. When 1, 3 or 4 are removed exaclty the same thing happens and it hangs in the same place. When disk 2 is removed I get "system error E04 cannot load kernel". Advice on how to proceed would be appreciated. The device is running firmware version 1.10.
