Is there an MFT file on every internal hard drive inside my PC or is it just on the C Drive?

It's an integral part of all NTFS formatted drives.

In fact there are two copies of the NTFS MFT in every partition that is formatted to NTFS. This is in case one copy becomes corrupted. And IIRC, you can't defrag the MFT, it's usually contiguous anyway, and the defrag get needs to read and write to the MFT as part of the defragging process.

As of Windows 7 you can defrag the MFT since they made it moveable (https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx), as such, it get defragged by the built in tool just fine.
Bitter note from experience: check you don't have any bad sectors before doing a defrag that requires a lot of file moving. You'll be fine most of the time, but our last failing drive had the MFT moved ontop of a bad sector and it wasn't pretty.
