Hello 7up!
I'm sorry for your problem!
Make sure you are following Jumanji's instructions on how to properly sue the recovery software. Since your drive is showing as Unallocated, and there's obviously a problem with the partition, as already discussed, you have very few options to try on your own. :/
You could either use a partition recovery software or data recovery software on your own, or you could use professional help. Usually, if there is some sort of additional minor or greater physical damage to the disk while it's in such a state, any recovery software used at a home environment hides the risk of further damage, both to the device and data, and recovery availability becomes less likely. Also, if the recovery software has difficulty recognizing a partition, this may mean it's beyond repair.
If your data is truly important, you could look into professional Data Recovery services, WD has partners in the field.
