I have a Thecus N4100 NAS wich had a 2TB drive in it configured as jbod partition.

Later I tried adding a second drive to expand the available space. I added it to the jbod configuration but I did not get any extra space. Then I tried removing the second drive but then the NAS system indicated the jbod configuration was damaged. After a reboot it told me there is no configuration and I need to create a new RAID/jbod configuration and that I would lose all data on the drive.

Of course I did not do this, I took the 2TB drive and checked with Linux if the partition was still there and it is... completely intact.

I found that linux recognizes it as a /dev/mdX device and that I should be able to mount it but I don't know the file system type.

Anyway.... is there a way to recover the data? Since everything has always been on a single drive it should all be there right?

I can connect the drive to Windows , Linux or MacOS so whatever gets the job done.
