My Cloud Did Full Factory Restore, incorrect free space 1 tb missing

i found out that when I did the Full Factory Restore, since the hard drive is too busy and slow (firmware 4.xxx made this possible) it did not fully deleted the previous files that i have on the drive. So when I hard reset (button at the back) after the Full Factory Restore the system was restored but still have files in which the dashboard don’t see. That’s why it see’s 1.3Tb only…
Now i was able to fix My Cloud using a guide from another post…
here…

Thank you very much guys! I used the firmware 3.xxx. My Cloud is now working 100%
Thank you, thank you specially FOX_EXE you’re the best!
