Sorry if this is basic i'm new to all of this,

 

So came back from work today and I found I had 1 Smart error in array, My disk shows ( Unmountable: Unsupported or no file system) 

from this when i tried a Smart extended self test it goes to 90% and gives me a read failure.  

 

Also I had isos share yesturday, and well its not here anymore. 

 

Im at a loss I will send my diagnostics if it can be of any help

 

Thank you in advance

The drive needs to be replaced but it seems you don't have a parity disk so there is no way to rebuild.

 

To fix unmountable you have to check filesystem, but not sure how well it will work since the disk is failing. If you had parity you would be able to work with the emulated disk.

 

How important is this data?
