Is your volume gone? Or HDD can be detected and volume still there, but you can't see the shared folder?
You may describe more about your problem, if possible, that you can provide the sceenshot for your problem.0 -
If possible You could try to provide screenshots from "Storage Manager".
As many as possible...0 -
Hier sehen Sie einige Screenshots von "Storage Manager". Ich habe sie in einer Word-Datei zusammengefügt.0

I think the volumes are ok, but the RAID 5 array is destroyed. What do you think? Can you help me?

So far it tells that the raid manager has assembled the system- and swap volume. But it doesn't do anything with the data volume.The 4 disks all have 3 partitions, and a GPT.But the most interesting piece of information is lacking. Does
