From page 28:
Do not format the card on your PC or other equipment. Format it on the camera only to ensure proper operation. (P62)

I didn't format any if my cards to anything because I didn't know you had to... I used a couple of my cards with a diff canon camera about 6 months ago and that didn't affect anything... The only thing I think could be wrong is using these cards on a pc would mess them up from working on my Mac.

Simply "using" them on a PC will not change the directory structure or format unless you copy random stuff from the PC to the card (don't ever do this).
A Mac can read and write Windows FAT 16 and 32 formatted storage media and read Windows NTFS formatted storage media. To write to NTFS, your Mac needs a free piece of software called NTFS3G.
When I put my Panasonic camera's SD card into my Mac, Get Info tells me that it is formatted as FAT32, a Windows file system. Formatting in the camera adds some files that it needs to operate correctly. Formatting on either a PC or Mac won't provide those files and the camera will not work as expected.
Look at it this way, you can put a movie on a DVD but it will just be data. To make it into a DVD Video disc that will work in a set top player it needs a strictly specified set of files on it that tell the player how to present the movie.The storage cards in AVCHD cameras also need a similar set of files to do much the same thing. This is why you always point FCP at the card itself, not the sub directory where the actual shots reside.

Thanks for explaining it better, once I can get this footage working I will format all my cards,
But does anyone know why my cards have stopped being detected in FCP after working fine for 2+ years? Is there anything I could try to do do fix this, I don't want to have to pay for a .mts converter

You don't say how you're reading the cards. If you're using an external card reader, this may be the cause of the problem. I've had several card readers fail over the years. If the cards show up in the finder, that's not the problem.

I almost had to laugh after I read your post. Out of the clear blue several days ago, the same thing happened to me with a Compact Flash card I've used successfully for 1 1/2 yrs. It wouldn't show up on my computer, wouldn't read or format in my Sony Z7U which is where I have always and only used it, nor would it read or format in a Canon 5DMII which also uses compact flash and I was desperate to see if anything would read the card.
It was a SanDisk Extreme Pro 32GB. After doing some research on the web, I eventually contacted SanDisk and asked if they would replace it under warranty. To their credit, they said they would. I have sent it back but not received the replacement yet. Fortunately the files on the card I had already gotten off.
So I guess cards can just quit. Does seem interesting that so many of yours have failed.
More of the story--the card being unreadable had happened right after I had given it to a colleague to use the files on his PC. I'm just sure that was co-incidence. He only copied the files and ejected the card 'properly'. I gave him another card with new shots from this weekend and just got it back a few minutes ago. It still works fine.
I only used my card in the Sony Z7U. At first I would reformat it each time I had a new shoot. The last few months or so I would just erase the files before a new shoot.
I'm going with it was just a card failure.
