Kinda stuck, any help would be appreciated. Here's my dilemma: Used to have a Windows laptop, have 2 external hard drives (NTFS) that were used on windows. Now I have a 2011 MacBook Pro, and my hard drives are obviously read only on it. Which makes them somewhat useless if I want to use them as a back up, or even to add/remove/rearrange files on them. What I was hoping to find out is: 1) if there's any way to get write permission without losing the data 2) what format should the drives be in (can't use FAT32 because I have dozens of video files larger than 4gb) I THINK I'm stuck here, because even if I had space to empty my drives and keep the information on them elsewhere (which would probably take a month to move the ~1 TB of info), I cannot put a lot of it back if the .mkv files are too large for the new format. Help!
