I've a lot of files in Mac and my time machine back up drive now. Since most of my files are spreadsheet, doc, MP3 files and they can inter use in my Mac and Windows 7 PC. There are 4 Mac partitions and one PC partition in Mac Disk utility I can use. Do you know which partition I can use and Windows 7 PC will see them. In this case, I can just use that partition transfer the files form Mac to PC? Please advice. Thx!
