[SOLVED] HDD error: Invalid MS-DOS Function :When doing ANYTHING!

[Xavi3rify]

What does it mean?! It's a new hard drive, never dropped, never damaged, formatted properly...

What's happened? I can only read files, not write to the drive...

I'm going to try getting it replaced through warranty, 121GB OF DOWNLOADED GAMES!!!!!! AAAARRRRGGGGHHHH!!!!!

Please help me ASAP! I don't know what to do, I have 121GB of stuff on it that would take a while to copy to disks so I don't really want to format.
Do I have to format though?

BTW, it's a 2tb Seagate Barracuda 7200rpm.

I try to stay away from third-party adware and shareware, and free-trials.

Just found out that stupid Windows automatically enabled 'Write Caching' on the disk. WHY WINDOWS WHY????????

I still need help, I haven't resolved it yet! Now it's giving this error: 0x8007045D

According to Google it could be anything.

Well, get Linux, get GParted, format it, done.

GParted is the best, thank you everyone who made it!!!
