Question about External hard drive

When is say 320GB on the box is it supposed to be 289 in reality/:confused:

My external HD has 298GB :shrug:

It's not uncommon.
I'm not sure why it happens - perhaps for some sort of memory cache or something, but harddrives tend to be smaller sized than what it is advertised for.

it also happens in every single HD (even Thumb drive), not only external ;)

when it says 320 GB outside it means that it has 3200 MB

but......

for us : 1000 MB = 1 GB coz it's approximately
for PC : 1024 MB = 1 GB coz it's the real amount

so
1 MB = 1024 KB
1 KB = 1024 B
and so on.........

but we said 1000 MB = 1 GB coz it's easier to remember (and to calculate) for us people ;)
though it's officially 1024 per unit, not 1000 ;)

so when it said outside 128 MB you will get only 120
so when you got 256 MB you will got 248 MB


I believe that explain something, not much or less ;)



but don't ask me to calculate, I'm f---ed up at math :lol:

if you ask me how I knew, get this :

usual size for SD Card
128 MB
256 MB
512 MB

don't you see something? ;)

1024 can divided by all numbers above, coz it's actual number of PC, but not what we learned

besides,
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1024

:shrug:

The amount of data on the box refers to the raw capacity of the drive. To make it usable it has to be formatted, which costs some disk space. Also, the manufacturers calculate that 1000MB= 1GB, while the actual conversion is 1024MB= 1GB, so the numbers on those boxes are somewhat inflated.

Hope I helped :wavey:

and they all teach us that it's 1000, not 1024 :haha:

Thanks all. So basically I shouldn't take it back in a flying rage?
