I have trouble with my NAS.
Recently I built up a tiny NAS with a Raspberry 3b+ and an external drive according this instruction:
Few days later the Raspberry was not even able to boot up. When I repeat the procedure with another SD-card it works fine, the Raspberry boots up and I can access the NAS settings by OMV web interface. So I assume the first SD-card is damaged.
My problem/ my question:
How can I access the data on my external drive now?
If I repeat the procedure with a new SD-card and plug in my external drive, I can not see my old folders respectively have to delete the drive before I can use it, right?
Another possibility is (in my opinion) to access the data by (Linux) PC. If I connect the drive via USB to my PC, my folders are visible. But there will occur a message that shows I am not eligible to access the folders if I try to open them. Permission denied
Does anybody have a clue how I can access my data?
Thank you in advance!
