I have to return my MBP because the entire case wobbles cause it's warped and the right fan makes an annoying high pitched noise. Anyway, I decided to back up my HDD using SuperDuper and making a sparse image. I saved it to my desktop and went to work, came back and it said it was unsuccessful due to insufficient space so I'm thinking "Oh, I'll just put it on my External HDD (WD Passport)" and then finish it after transferring. But I get an error and I'm assuming it's because it's Windows formatted.. Problem is that I have a lot of backed up programs, videos, homework, etc. and I don't want to reformat it for mac... Is there a way around this? I'm thinking of partitioning my External HDD and formating that partition for mac. I don't really know how to do that though. Any Thoughts? I'm sure I'm not the only one.
