So I have my Macbook pro with it's 200 gb hard drive, which shows up with a ~185 gb capacity. This is normal, with the ~15gb for whatever hard drives require that extra space for. So, my friend just got her 2.4ghz/160 gb white mac book today. I am setting it all up for her and I am seeing something odd. The hard drive has a 160gb hard drive, when I look under "About this Mac" and then "Serial-ata" it shows its formatted capacity at ~149 gb, which is normal. However, here is the problem...When I check info on the Mac hard drive, it is only showing Capacity at 111 gb, same thing in iStat pro. Has anyone ever experienced this issue before? The comp has a 160gb hard drive, the formatted space is 149 gb, however, the capacity is only 111 gb. Now this this not the AVAILABLE, that is showing at around 90 gb, this is the potential capacity of the drive, and it is only 111 gb.
