2 T disappeared and but disk says files are in it. Still 1 T left on 3T

Hello,

Not sure what is happening but I have those 2 Mycloud of 3T since 3 months and worked like a charm … Today one of them just acted strange. All shares folders were gone, users left, but it looked like all were gone but then the original folders when I got it at the first time… were there… Did reboot everything. difficult to get some results… and now… I can see some part of folders ( called applications ) which was inside it own share folder. Those folders and files right inside the Public folder . I just have no idea what is happening…

I am on a Mac. and did get few virus … when I worked on a windows clients computer…

Can it be the issue ?

Looking around and was able to login in ssh … but still not sure what to look for…

root@WDMyCloud root # ls -alr
-rw------- 1 root root 38 Feb 13 04:26 .ash_history
drwxr-xr-x 4 root root 1024 Jan 11 03:36 …
drwxr-xr-x 2 root root 1024 Feb 13 04:25 .

Can I retrieve those files ? I am afraid to to anything… now… afraid to lose all the files…

Thanks for your quick help and reply
