820838 2009-10-15 05:46:00 Yesterday while on AIDA32 I found something interesting.
It said that I have a WDC WD800JD-75MSA3 Western Digital 80GB HDD.
I was suprised at the 80GB, because in diskmgmt.msc (Disk Management) it says I have only 75GB. Does anyone know why?
And when I go into cmd > diskpart > list volume > select volume 1 > list partition it says:

Partition ### Type Size Offset
------------- ---------------- ------- -------
*Partition 1 Primary 75 GB 10 KB
Partition 2 Extended 24 GB 50 GB

Why does it say Partition 2 Extended 24 GB 50 GB
What does the 50GB mean?
Doesn't the WDC WD800JD-75MSA3 have only 80GB? (It says 75GB+24GB)
Whats the * for?

Thanks

Yeah that's about right. HDD manufacturers think 80gb is 80,000mb rather than 81 920...

Edit: I realise that would be 78gb not 75, but I guess it's just marketing (or I'm wrong).

820841 2009-10-16 01:49:00 80GB (disk manufacturer) <=> 75GB (operating system)

is about right

80,000,000,000 / (1024^3) = 74.505806
