[HELP] Can't mount SATA drive

I have software that I really need to use on this drive, like Final Cut Pro, and it's not mounting. First people were saying it was because the disk was ExFat so I partitioned the drive (took like 3 hours jfc) and I made a Mac OS extended partition. But this ALSO WOULDN'T MOUNT. This whole thing is just a pain and I have no idea why this is happening. The 2 partitions switch between being mounted and unmounted. I know it's a problem with Hackintosh because the disk works perfectly fine in Windows.

​

Error I get when I try to mount the MacOS Extended partition

I usually don't like to beg over stuff like this but please someone help me I have important software that I need to use soon and I can't just reformat the entire drive as it has over 1.3tb of stuff on it.
