Hi,
I dropped my hard drive unfortunately and it won't show up on Explorer. It does show up on Disk Management and Device Manager though but only a part of it.... My Seagate hard drive is 4 TB and on Disk Management is says 3.86 Unallocated.

I have tried at least 8 partition and data recovery software and none can find the terabyte of data that was on it. I even plugged it in internally but it won't read at all.

So I was wondering if there was a way to find the missing 99% of my hard drive and recover it or is it a hardware issue that I have to spend money for?
