Where did my other Media Types go?

Question

I just upgraded from 10.2.8 to Tiger and now when I choose our old color printer (Xerox Phaser 790) the other media types are not highlighted in the drop-down menu as available. I'm trying to print out of any application and looking under Printer Features/Set 3/Media Types. The only option available it Plain Paper, and they all used to be, so I'm not sure if I'm doing something wrong or if there is another problem I should be worried about.
I've attempted to reinstall the driver and that didn't work. I just spent two hours searching for someone with a similar problem but haven't found any, so if anyone has any ideas I'd appreciate them.
Thanks.

Answer 1

As a general rule, the actual reported capacity of a hard drive is about 7% less than the advertised capacity.
The discrepancy you are noticing is due to the differences in the way that hard drive manufacturers calculate disk capacity and how it is reported by the operating system.
HD manufacturers use a decimal measurement to calculate disk capacity. They consider a gigabyte (GB) to be 1 billion bytes.
The decimal measurement would be 1000 x 1000 x 1000 which equals 1,000,000,000 bytes. For example, an 80GB hard drive means that the disk has an unformatted capacity of 80 billion bytes. (80,000,000,000 bytes.)
Since computers "speak" binary, not decimal... the operating system calculates a gigbyte (GB) differently.
The binary measurement would be 1024 x 1024 x 1024 which equals 1,073,741,824 bytes.
Using the example above, an 80GB hard drive would be reported by the operating system as 74.5GB.
80,0000,0000,000 / 1,073,741,824 = 74.5GB
1GB iPod = 930MB
2GB iPod = 1.8GB
4GB iPod = 3.7GB
20GB iPod = 18.6GB
30GB iPod = 27.9GB
40GB iPod = 37.2GB
60GB iPod = 55.9GB
Since the iPod operating system and extras also take up some space, you will be left with slightly less that the above stated capacity for your content.
Apple also explains the above in this article:
