Why does my out of the box 1tb ExHD have less space

[Amnak]

So i took the plunge and bought a 1TB external HD but my mac says it only has 930 GBs. I'm assuming it's the crappy installed software thats on the thing. It says i can't delete it but I'm sure you can. Basically help

Beacause of the term 'formatted'. It's not the crappy software.

if you're using a mac with snow leopard it will show up as exactly 1000GB but an older mac or any pc will show it as 930GB. snow leopard used base ten rounding while the older macs and pcs use 2^X rounding which not what the hard drive makers use.

Ok so I do have 1000gb? then how in the world do i get the folder off? I'm worried that if I format I won't get the space back. For example when i formatted my 8gb flash drive with out taking files off it left me with 7 something gbs.

You have 1000 GB, or 930 GiB. Your machine is reporting your GiB count, which manufacturers wrongly label GB. There is nothing wrong with your drive.

to add a little more english

GiB - uses the computer based binary, so based on units of 1024 Bytes

GB - uses base 10 math (what you you normally use), so numbers are based on units of 1000 Bytes

1 TB
based on GB = 1,000,000,000,000 Bytes
based on Gib = 1,099,511,627,776 Bytes

Manufacturers typically uses the Base 10 number because they appear larger

but computers, based on binary use GiB, which give you a smaller number.

It's basically been this way for years
