I recently purchased the last version 2.8 24" iMac which I love. It came with a 320G drive. I have been with computers for years and know that hardware and software report byte size differently. Especially between Windows and Mac. But it took me about 2 weeks into having this machine to look at how much space I have left on the drive only to discover that it is only reporting a 297.77G drive installed. Now that is ridiculous, if it was a 300G drive then the reporting of 297G would be ok with me. This is this is (32.? GBs) missing. Is this normal for a drive of this size? Has any one else had this problem? Please could someone else with a 2.8 iMac with the 320G drive check theirs and tell me the result before I call Apple.
