"What can I do to perform HDD unallocated space recovery to rescue my data? Recently my 2TB western digital external hard drive which is used for file storage shown as unallocated space and all that data on it became inaccessible. About 2 hours ago, I attempted to open up the drive and put it inside my computer since I no longer needed to go around with it. But the drive wasn't showing up in my computer but it was showing up in disk management. It says the whole drive was unallocated.

I didn't touch anything since I was worried I might delete all my data. so I was hoping to make it external again by placing it in the shell case, and plugging it via USB port would fix it. But it is still saying the whole drive is unallocated. Please, I do not want to lose my data."
