Scenario: 1TB NAS drive hooked up to AEBS, one partition for OS X and one partition so I can store files from my laptop PC. Fairly easily done as I understand. Question: If data from the PC is on the same NAS drive that my iMac see/uses, is any of the data cross-compatible??? In otherwords....if I store some iTunes music on that drive from my PC, can I use that same data on my iMac or are the two data systems (even though it's a music or video file) completely incompatible and/or they cannot even see each other?? Thanks!!!
