Hi there,

 

I had a few random shutdown's / freezes die last weeks / months. Afterwards the parity check was always running. I thought it was due to the unclean shutdown - maybe it wasn't.

 

So today my server was down again... but this time the array won't start because my appdata / system .. is on the cache ssd. I think the sdd is not completely dead, since I saw the files in the file browser before I restarted the machine - but they might been only the cached filenames ..

Anyhow, I want to recover my data from the disc since I think the data is still on it.

Is it just corrupted ? Can I trust this ssd again? Should / Do I need to buy another one? 

 

Thanks for your help.

fixed it
