Actual Hard Disk Capacity ?

First, Wes has the fact correct in that an 80GB drive does not
generally hold 80GB of data, but something smaller and 72Gb is
probably about right. However, his reason is amusing but incorrect.

No, actually, he's right. (Yes, I said Wes is right. He's annoying,
but not always ignorant.) Basically ALL hard drives are sold using
base10. 80GB == 80,000,000,000 Bytes. But nearly all operating
systems - including TiVo - use base2. 80,000,000,000 Bytes = 74.5GB.

I stand corrected. I'd swear that I've had disk drives labelled in
true power of 2 byte sizes and still seen significant fall off once
formatted (and even seen the labels indicate such as "80Gb
unformatted, 72GB formatted"). I also remember certain IBM software
items refering to things in power of 10 quantas, presumably because it
makes the numbers larger. However, I rarely pay a great deal of
attention to such things, so perhaps my memory is at fault....

OK, so he was right and wrong at the same time. :-) Right in that it
is the different base - base10 vs base2 - wrong in that he said
'base16' which is bull****.

Hey, it *is* Wes. ;-)

And for you morons, hex *IS* base 16. I've never heard of base 2 except as
binary. Oh, hex stands for hexidecimal for those that can't figure that
out. All computer op codes consist of hex, as does the numbering system
normally, though some CPU's do have a decimal mode of operation, and some
older ones may use octal (base 8). The fact that that I didn't mention the
FS taking up more space is simply because I didn't see it as necessary for
the info the OP needed. But in here I guess if I said the sun was a ball
of fire, ya'll would say I was wrong because i didn't explain the atomic
structure in detal. So be it.

For you people that don't understand this here is it in a form you can
understand. Normal size of HDD is sold as decimal. Your computer normally
reports the size in HEX. yes HEX, not base 2 or binary as some so called
informed person states. Now here's an example everyone should be able to
understand. df is the normal linux command to display mounted filesystems.
It defaults to base 16 when calculating the size. Using the -H option will
change that to base 10 (the size they are sold at). Note /dev/md0 is a 2
drive raid0 array consisting of 2 320G drives and then note the huge
difference in reported sizes. If you run a linux system. look at man df.

Uh Wes, it would be a good idea to quit while your not too far behind.
The only reason you think computer opcodes are HEX is because for
convenience that's they way we write them down. Inside a computer all
data is represented in binary format. HEX is just a convenient shorthand
because it makes it easy to write down long binary strings as much
shorter character sequences. No computer represents numbers in decimal
or has a decimal mode of operation, perhaps you are thinking of BCD
encoding? And no, older computers didn't operate in octal we've simply
used octal as another convenient shorthand for binary.

Actually I need to correct myself. I typed the above pretty fast. It uses
a power of 1024 by default instead of 1000. 1024 is based on hex, while
1000 is based on decimal.

As usual in your case, it did not take long for you to get your whole
foot in your mouth once you toe was there. You have demostrated well
your superficial understanding of even the most basic concepts of
computers, or in this case digital circuits in general. They have 2
states, they're base 2. The fact that binary data is frequently
compacted in hex representation for convenience has no relavence to
the underlying hardware.

As MZ said, you are correct that 2^30 (what some people in the
computer industry call a giga) is not 10^9, but this only partially
answers the question the op asked. He is looking to explain a 30%
discrepency, not a 7% discrepency.

Stop digging while you can still see the top of the hole.

Hex is based on 16, which is 2^4. 1024 is 2^10.
What power do you raise 16 to to get 1024?

Well, no **** Sherlock. Although with registers 64bit wide or more no one
hardly refers to binary any longer. It certainly has nothing to do with
HDD space.
