I have recently switched from pc to mac. I have an NTFS formatted external hard drive that I would like to have access to from my mac for Carbonite backup and read and write. I understand that I cannot reformat the drive without losing data but can I format a new drive in EXfat, move the data from the NTFS drive to the new drive and have full read and write access to the data in the new drive now formatted for MAC? Or am i just stupid?
