187gb showing for a 200gb

post #1 of 10
Thread Starter 
Hey guys,
I just picked up a Maxtor 200gb drive for 30 bucks, no rebate at Staples.

When I ran the included utilities on the drive, it showed up as having 203 gigabytes of addressable data. Then, I copied my old drive to this one and when I opened its status in windows it showed up as 187gb. I know that you lose space when formatting but, wow, thats a lot. Especially when I was +3 gb to begin with. Any thoughts?

well 1000KB doesn't really equal 1 MB they use that method cause it's easier. Hard drives always have less space than it says

Well theres 1024kb in 1mb.. But HD makers count 1000kb as 1mb, when its not, and when the space is truly addressed, it shows up as less..

Basically you miss out on 7% of your drives space. And 7% of 200 is? 186 so i would guess that it is just marketing error. The marketing departments for hard drives think that 1000kb is 1mb when it is really 1024kb. Just count on 7% of what the BOX says will be missing

It shouldn't show up as 187, it should actually be around 195gb, I have a 200gb drive and they do use the 1000kb=1mb crap.. but 200000/1024 = 195 rounded down. Maybe its just the drive or the partition/format, try contacting the manufacturer if your worried about it. Oh and check the windows utility to see if theres any free space on the disk.

Do the math on your drive I have always noticed the 7%
my 250gb drive has only 233gb
my 80gb drive has only 74.5gb

It is because of marketing.

Really 1024bytes = 1kb
A megabyte is 1024 x 1024 so one megabyte is really 1048576 bytes
and one gigabyte is 1048576 x 1024 and that equals 1073741824 bytes
73741824bytes is almost 7% of 1GB so 7% of what they advertise is going to be missing.

EDIT:::: If you want to get technical 6.867742538452148% Is pretty much Exact

The file system takes up space too.
How much space is missing depends on the type of file system, cluster size, drive maker, and the size of the drive.
