I have a server I run at home that uses ESXi 5.1. I had a power outage the other night and when the server came back online the secondary HDD which contains a lot of my labs no longer shows as a datastore. I can see the physical disk and when I select to re-scan it doesn't find it.
I can see in the CLI that the disk has a partition and I am able to create a new partition (I haven't as I don't want to overwrite).
How can I recover the partition?
