MBP Hard Disk size

[sunrobby]

Hi, i have MBP 2.0 Ghz model with standard set, means 100 Gb hard disk, but when looking at the system profiler, it said the capacity is 93.16 Gb, so where do the rest of 6.84 Gb? My iPod 30 Gb is not really 30 Gb though, i believe some part is used for the system, but cmon, this is 6.84 Gb lost, it's quite a big space lost

By tradition, ALL hard drives are measured such that 1 kilobyte = 1000 bytes, and so on, and all computer operating systems measure 1 kb as 1024 bytes. This has been true essentially during the entire life of the personal computer as we know it.

The difference, in both cases, between the stated formatted capacity on the iPod or the MBP HD, and the list size, is explained by this difference (1 GB = 1024 x 1024 x 1024 vs. 10^9 bytes).

I've always been bothered by that little calculation. It's not so bad on hard drives, but boy can it mess you up something fierce when you're mastering DVDs for replication!

Hm ok, so it's not really 100Gb by the calculation, thanks for the explanation Why does apple not stated the real disk size so that the buyers wont confuse bout this..

You can blame the manufacturers of hard drive who decided to go with 1MB = 1000 KB. It hurts me more though, I have a 250gb hard drive and I'm only given 233GB. That's 17 gigs gone!

For the exact same reason that all computer manufacturers do, to save a couple of cents (plus on the website it says 1GB = 1 billion bytes (actual formatted capacity less)

every time you move from MB to GB to TB to PB you lose more and more space percentage wise.
