I've just installed Ubuntu and completely replaced my Windows 10 because I don't want to use it anymore. Installation went very well and everything is working fine but one issue is that I've installed Ubuntu on my SSD drive that seems to work fine but I've another 2TB disk and its partitions are not being recognized by Ubuntu. It just shows as LDM data partition. Please kindly help me fix this, I've lots of important data in that drive and I don't have any backup.

Following is the screenshot of that 2TB drive of "Disks" tool.

If you did not mess with your data yet, you should first make a backup. You could connect it to a Windows system and backup, as mentioned by heynnema.

You would need another disk. In some cases, you could split your data partition to have one as a backup (if the space taken by data were less than 1Tb), and then work on your original data partition. In this case yo cannot do that, since you would not be able later to change the partition type of only one partition.

Then you can reformat your disk, and recover the data.
