Disk advice!
 

So I have some information on a 3inch Floppy disk that I need. I tried to access it but it said I needed to format the disk. I wonder if its because I'm on a PC as the disk was created on a Mac many moons ago.

Any ideas?

Bring it on over, I can get the info off it :)

Exactly what you thought. PCs cannot read data from Mac-formatted 3-inch floppy disks, especially from back then. So, you need to either use an older Mac which has a built-in floppy drive or find an external/removeable 3-inch floppy drive. If you need help with this, I still have a "beige" Mac that worked the last time it was turned on, which was several years ago.

And if not, I have a USB floppy drive which I can plug into my Mac
