iPhotos eHDD Format Inquiry and Windows Compatibility? I have a Seagate Backup Plus Slim 1TB external hard disk drive that I'm using to store a lot of large files. I have files from both Mac and Windows (as I use Parallels). I was trying to create a new iPhoto library on my eHDD when it started to give me an error. I think that iPhotos requires Mac Extended (journaled) or maybe exFAT format for a library to be written to that volume but I'm not sure. Even if I did, would my windows files work without any issues on Mac Extended? Is there any way to create an iPhotos library on my eHDD hopefully without formatting it?
You can create a second NTFS partition on your windows machine, then reformat the new partition on your mac as Extended journaled as per Apple specs.
