Hard drive question

Hi I purchased a new Sony laptop. The specs said I have 320GB, but when I check the drive, I have 270GB free of 290GB, I understand 20Gb is been used for Windows 7. But where is the rest? 30GB?

Thank you

Well, they advertise them as 1000MB's per gigabyte. In reality, there are 1024MB in a gigabyte, thus the loss.

HDD's - the Advertized size vs the Actual size.

Even with your calculation its still doesnt add up to 320GB.

290 * 1024 = 296,960GB...

Is there a different way of calculating?

Your 320GB space worth only 298 or so GB, so from start you already lost 20 so GB... what are you missing?

The advertised space for your HD is 320GB. The companies go by the "assumption" that there are 1000MB in a GB, which is wrong.

There are actually 1024MB in a GB. The math you did was how many ACTUAL MB are in your HD by multiplying 1024, the number of MB in a GB, by 290, the ACTUAL space on your HD.

Let's do the math that was giving in the example on the link I sent you but instead of 500GB, we'll use 320GB.


320.000.000.000 byte / 1024 = 312.500.500 Kbyte

. . 312.500.500 Kbyte / 1024 = . . . 305.175 Mbyte

. . . . .305.175 Mbyte / 1024 = . . . . . . 298 Gbyte

8GB off, close enough .

Those periods act the same as commas.

Thank you all for your help. (I guess I got cheated by 8GB)

It works out to just over 93.1 percent of advertised capacity; aka 6.9% shortage.

.931 x 320 gigs is 297.9

.931 x 640 is 595.8

.931 x 1 TB is 931 gigs

.931 x 1.5 TB is 1396.5 gigs

etc

I will be purchasing a new SATA hard drive. Currently, I have a 120GB drive of which I've only used around 60GB. Most of the hard drives I see at my computer store are 320GB, 500GB, and 1T. This would be overkill for me. I'm thinking about getting one of the 500GB hard drives and making two...
