Hi,
I installer OMV on a raspberrypi and used 2 external, self-powered, HDD, 1TB each.
Suddenly this morning I noticed I can't access 1 of my HDD. I can see it's listed under physical disk (/dev/sda), however, it's not detected in File System, filesystem ext4, but no label, no info on total, used, and available space, it's not mounted, though referenced, and its status is missing.
What can I do to check and try to get back the content of the missing HDD? A lot of data inside so I prefer if I could try non destructive method first.
Thank you,
update 1: reattached the external hdd to omv, but now it doesn't detect the partition at all, listed under /dev/sda/ but no partition
