320 gb hard drive shows up as 305 gb

Hello

I recently bought a Maxtor 320 GB SATA II (300) hard drive. When i installed it into the computer the SATA controler picks it up as a 305 GB hard drive. I'm not quite sure if that is normal. When formated it shows up as 305 GB??? I don't believe 15 gb would be reserved for the FAT table.

That's normal. Windows uses a different definition of a KB than hard drive manufacturers

Its gibibytes vs Gigabytes

just do 320 *(1000/1024)^3

320GB drives format to 298GiB by the way.

320* (1000 * 1000 * 1000) / (1024 * 1024 * 1024)

I kind of asumed this was normal. I remember a while someone else told me that the Allocation table of the drive takes quite much space. I'm not sure exactly how much space it was formated?????

it probably shows up as about 319,980,000,000 or so bytes though doesn't it?
