i love how these idiots are coming up with fake answers. the person i quoted is correct though....ceewi1 said:This occurs because drive manufacturers label 1kb as 1000 bytes, whereas Windows correctly identifies 1kb as 1024 bytes.
Now, doing the maths: 250GB @ 1000 bytes/kb = 250 * 1000 * 1000 * 1000 = 250000000000 bytes.
250000000000 bytes @ 1024 bytes/kb = 250000000000 / 1024 /1024 /1024 = 232.83GB, which rounds up to 233GB. This is the case with all hard drives, it is not a fault or unallocated space, it is simply deceptive marketing.
