I’m no techie either but FAT 32 is a disk formatting thingie. That’s it. Whatever it is, it makes both makes Mac’s and PC’s happy and they both can ‘speak the FAT32 language’. Using Disk Management on PC (that’s how I did it), or something else on the Mac you go to format the drive when you’re good and ready and it’ll ask what file format you want it in. Very easy. Hell, I did it and I don’t even know what I’m talking about.
If you format your external drive as FAT32, it should work. The only problem might be that you mentioned it’s 250 gig’s. Someone I’m sure will correct me on this or have more techie than I info but FAT32 doesn’t like drive partitions over a certain limit. So – off to Disk Management and / or Disk Utility with ye!
So, if all my information isn’t perfect, someone somewhere can remind me of my limitations and correct me on the intricacies and history of the FAT32 file structure. Your drive should work eventually. And we’ll all live on to healthy and productive lives. That is except for the guy waiting to correct me…….
