I'm currently saving my pennies so that I can be a "switcher" sometime soon. Hopefully, I'll be able to get my first Mac, an iMac G5, when I graduate from college. Although that's 7 months away, I am already planning for that day, so all my computer-related purchases are geared towards that eventual date of switching. To that end, I am looking at getting an external hard drive for my current PC (a Gateway XP laptop... crappy, I know). I need something to backup my data, since I'm always afraid this laptop, although only 2+ years old, will die any day. My question for you Mac experts is this: will there be a problem transferring data from an external HD to my iMac? I know that, for example, my iPod is formatted for PCs, and so when I switch, I will have to reformat it in order to use it. Will I have the same problem with a hard drive? If so, what is the best way for me to backup my data? I don't want to get an external CD/DVD-RW, since my iMac will have one. Thanks in advance for your help. I know I'm a "newbie" but I've followd these forums for quite some time.
