Summary:
My HDD is (pretending to) fail. I tried a few types of recovery software, none of which seem to help.
Except for one. WinHex. Proof. It views it perfectly.
I have no clue what hex editing is. I'm not even sure what this software is for. As far as I know, it is not designed for problems like this. If it has a function that could possibly save it, I do not know which nor how.
What is happening, why can only this software read it, and how do I restore my drive to its normal state?
Extra info:
Specs:
Win 7 Pro
Samsung laptop
LaCie Porsche 4TB External HDD drive SATA via USB... with very rare data.
Noise: The disk doesn't make any typical HDD-fail sounds.
About WinHex: The folder sizes look small, but once you get to the actual files they are all accurate. Everything's there.
SMART: Someone recommended me to do some SMART tests, and research led me to smartctl. Someone else recommended GSmartControl.
This is what it says:
smartctl 5.43 2012-06-30 r3573 [i686-w64-mingw32-win7(64)-sp1] (sf-5.43-1)

This should be enough information, but just in case you'd like more anyway, (I recommend skipping to save time), more after the break.
How do I save my obviously saveable disk?
Redundant Backstory:
Been having sudden, unexpected issues with my External HDD. Went to do some preemptive work, ran HDD Regenerator, it asked me to disable AHCI mode for my drive, which as far as I remember was working just fine, so I did, and as soon as I switched the option in BIOS and reset it, while loading Win7, PC gave a quick BSoD and flashed off only to repeat the cycle every boot.
So I re-enabled AHCI mode and weirdly enough the issue was fixed.
Except for my HDD. It could never be accessed again.
I tried numerous recovery softwares and methods, none of which gave results, or would just hang, until I somehow got WinHex which shows me the entire drive's contents, in seconds, perfectly complete, can browse it from inside the GUI, no issues.
Thanks so much in advance.
