More than likely it was a sector with a simple error due to me knocking out the OEM recovery part of the drive - Doesn't mean that part of it was bad, it was probrably scrambled and showed up as an error.
Doing a complete drive wipe with DBAN is what fixed it and now the error is gone, that much I can tell you but it took wiping the entire drive to do it.
Fdisk and all else I tried coudn't make it go away so that's what I had to do in the end.
If you don't have a DBAN disk, grab a copy of the program then burn it to a disk and it will come in handy one day.
