My HD shows up in Gparted as unallocated but it isn't showing up in File (same thing in windows Disk management and File explorer)

I am used testdisk to recreate the partition table and I was able to recover my HD and all the date without formatting it.

1. In the terminal enter testdisk
2. Then choose create a log
3. Then select the HD Choose the partition type (most probably Intel)
4. Then select Analyse
5. If you only had 1 partition in your HD, then just mark the one that shows up as Bootable partition (with the left-right arrow). Then press "Enter" to continue
6. If you had more you should now do a "deeper search", otherwise choose Write

Unplug your HD and plug it again (this is what they mean, in this case, by "reboot")
