Before I flash the device, I ran a quick access to device through web interface.
And surprisingly, I am able to access it.
But there is an error message, fan is malfunction.
I ignore it, quickly format the disk, then after several process, it is good as new.
Thank god.
Now, transfering my stuff in that device.
If anyone else having the same problem as I am:
- Infinite Disk Checking
- After few hours disk check, could not access web interface (return 500 server error)
Then leave it for about half day. Try access it back.
If you can access it, please do not perform any disk check or disk erase.
Just perform disk format.
After several process and disk format completed, you are safe.
Now you can restart your device and do what ever you want.
Seriously, the technical team should provide extensive detailed documentation on these devices.
Easier for user to know what the hell is going on when/during some process occurred.
Thanks a bunch Paul for trying to solve mine. =)
