Back in the day, I was comfortable recommending and always formatting my external drives as FAT32. Why? Mac OS X could read/write to it. Windows could read/write to it. Now, FAT32's age shows and its limitations become very frustrating for backing up data (most notably, the limit of 4 GB on individual file size). So, in today's day and age- is there a good choice as to filesystem? Windows can't read Apple's default HFS+, and as I recall, Mac OS X can't write to NTFS, only read. Can Windows read anything other than FAT32/NTFS?
