Well Im pretty sure this is a stupid question but being brand new to the mac world I thought I would just ask. I just recently got my macbook (60gb hard drive, 512mb memory) no more than 3 months ago. I recently put all my pictures (about 800), my mp3s (about 2400), and my tv shows as well (about 20 episodes of 30min shows) transfered from my windows based desktop to my new macbook, I also have like 5 or 6 very small word documents as well. Anyway I am now getting this message that my start up disk is full. First off...could this be right? I was just shocked that my laptop was already full. I checked my disk usage in the activity monitor program and it says: Space Utilized:55.41 GB Space Free:166.68 MB, so according to this I figure that it must be full. I currently have all my videos and mp3s on my ipod and it says that I have 27.8 gb capacity with 16.3gb avaliable. I have my photos in a folder on my desktop (which I eventually plan on putting in iPhoto) and when I "get info" for the folder it says that it has 1.48gb. For some reason things just are not adding up for me. So I just thought I would post this to see what some experienced mac users thought. Last but not least if my laptop really is full what are my options? I know this was long winded but I just wanted everyone to have all the details. Thanks in advance for the help.
