I have a WD 250GB drive and Windows (XP, NTFS) shows it as 250,056,704,000 bytes. The summary line in Explorer declares that this is between 232GB and 233GB, however.
Dividing by 1024 doesn’t help because (I believe) many manufacturers’ calculations assume that 1K is 1000bytes, that 1M is 1,000K and that 1G is 1,000M. Windows, however, assumes that 1GB is 1024 * 1024 * 1024 bytes. So perhaps one needs to divide by 1024 to the power of 3 (1,073,741,824) to get the formatted size recorded in Windows.
I don’t understand how they calculate the size but it should be only called like 145GB than 160GB.
From Partition Magic, I can see
Western Digial 120GB = 114470MB
Iomega 120GB = 117796MB
Maxtor 160GB = 131069MB
No matter you divide it by 1024 or 1000, Maxtor exaggerates their size too much.
