.
the nas has warned me of a disk with failures, so I have replaced it with a new one of wd.
turn of nas, quito disk number 1 with defects and placed new disc.
start making backup (raid 1).
The next day I find the red LEDs of the two discs.
I look at reports and error number 2 disc !!!
I turn off the nas, I take out the discs and I try to turn on again after mounting the discs.
Now there is no way to access the data of any disk.
It says not to have RAID configuration ??? !!!
I do not know what to do, or how to access.
I have lost all the data ???
