Hi There - I'm new to the forums and I think I'm mac proficient but definitely not a pro, so bear with me while I try to be as clear as possible. After my brother stepped on my 13" black macbook (aka the love of my technological life), I felt compelled to go for the bigger screen and sprung for a used Macbook Pro. Shortly after buying it (from simply mac), I began getting messages that my startup disk is nearly full. I have some music, pics, and tv shows which I would imagine take up a decent amount of space, but I had way, way more on my old macbook, so I was perplexed as to why I was supposedly running out of space. At the advice of some other threads here, I downloaded WhatSize, which is giving me lots of insight into what's taking up space. My question is this - in WhatSize, under devices, it shows my Macintosh HD which has apparently only 169MB available. Down below in "places", it shows "macbookpro" (with the little house icon next to it) which is apparently 86.2GB, with "Music" taking up 77.4GB. Then, under places again, below it, there's "music," as its own separate "place," taking up 77.4gb. This is probably stupid, but I'm curious as to whether this is just the computer being redundant or whether, somehow, the music is stored in 2 places taking up equal amts of space? Also - what is the difference between my "macbookpro" as a place and my hard drive as a device?? Does that make any sense?? Thank you!
