YOU CANT

by jhansen In reply to bring back HDD

the missing part of the hard drive is taken up by the formatting of the drive. Yes laying down all those tracks and sectors requires some over head.

Remove Partitions

by uppulurivasu In reply to bring back HDD

If you can remove the complete partitions and partition tables all your 80GB shall be displayed. To write the boot sectors the approx 10% of your HDD is occupied, even in 20 GB HDD 2 GB is lost.

Sales math and hard drive space

by gralfus In reply to bring back HDD

You state that the "actual" space is 80GB, but that is most likely based on what the marketing team for that drive put on the box. They probably meant that the drive has a literal capacity of around 79779017523, which rounded up is about 80 billion bytes. They then say that this is 80GB, which is not really true. This all happens because bytes aren't measured using base 10 math, but base 2 math. Here is an example:

1 KB = 1024 bytes (not 1000 bytes)
1 MB = 1024 * 1024 bytes or 1,048,576 bytes
1 GB = 1024 * 1024 *1024 bytes or 1,073,741,824 bytes

So a literal 80GB would be 85,899,345,920 bytes. A marketing team would look at that and say "85 billion bytes, that's 85GB" which it isn't really, but that is how it works in sales.

A drive that has 74.3GB of *actual* space would have 74.3 * 1,073,741,824 bytes, which is 79,779,017,523 bytes, which a marketing team would label as a rounded-up 80GB drive.

So you really purchased about a 75GB drive, some of which will be taken up by formatting, leaving you with 74.3GB

Ha

There was a discussion regarding this topic last week. There are 1024 byte in a KB... and so on and so forth. It was hardly noticeable before, but now that the drives are growing to larger sizes, we are seeing this observation.

There are 74.5 GB in 80,000,000,000 bytes. Period.

You need to be aware that manufacturers are using the 80 gig notation based on the fact that there are approx 80,000,000,000 bytes. This, of course is wrong, but what are you going to do? You've been duped.

Yup

And as topics wear thin, so does my patience for writing a proper explanation.

Oh well. If they really care, they can dig up their info on TR somewhere else - like in the "new" link. I guess everyone got an 80 gig for Christmas. The only thing remotely related that I got was a secure 256 MB flash drive. I lose a bit of space because of the software used for the password authentication, but it's still more storage than 256,000,000 bytes. :)
