I just bought a Seagate Backup Plus 4TB drive for backing up some external drives I have. I already have a 1.5TB Western Digital drive I use with Time Machine that backs up my MBP's internal HD, but my externals are not included in Time Machine. Since I don't think you can use Time Machine with different settings for different backup drives, I'm thinking of using Carbon Copy Cloner for backing up my externals to the new 4TB drive. The Seagate 4TB comes as an NTFS drive, with an NTFS driver to work with Mac. So my mac can read and write from the drive even though it is NTFS. Do you think I should reformat the drive as HFS before I use CCC, or just leave the drive as is since it seems to work right out of the box with both Mac and PC? Are there benefits to reformatting to HFS? If I don't reformat, I will be able to use the drive with Windows and Mac, which seems like a benefit, but I don't know if I'm missing something due to ignorance. Also, I'm worried that reformatting to HFS will delete the pre-loaded NTFS mac driver if I ever decide to go back to NTFS. Secondly, do you think I should I install the Seagate Dashboard software? I think I saw a video where the actual Backup portion of the software called Protect does not even work with Mac... Thanks a lot! By the way, I'm on OS X 10.6 Snow Leopard.
