Windows 7: Need help with a couple of homework questions??

Need help with a couple of homework questions??

I am working with a computer that has a total storage space of 1TB...of this total space I have used 78GB.

1. Assuming that I should not use more than 85% of the total available space, how much total storage should I use?

2. If I use an average of 500MB of storage each week, how many weeks before I run out of storage space?

How do I figure out these questions? so #1 do I do 1TB x .85? #2 do I do 1TB divided by 500? Please help....thanks

Windows 7 Ultimate SP1 (64-bit)

1TB HDD: ~931,32GB or ~953671,68MB
Used Space on HDD: ~80GB or ~81920MB
Available Space on HDD: ~871751,68MB
85% of Available Space on HDD: ~740988,93MB

~500MB per Week
~1481 Weeks or ~28 years until 85% of the HDD fills up (with the previous data)

Of course this is theoretical. Real world is another thing :) but that'll give you an idea.

This is only an approach, you need to find out how many GBs do you get left after formatting. then substract the used GBs to that number, then multiply the available space by 0.85 (which is the percentage you want to use), then divide by the number of MB per week you want and then you have the number of weeks, divide weeks by 52 to get how many years and that's it :)

Windows 7 Home Premium x64 SP1

There are 1024 gig in a TB(binary) therefore 85% of that is 870.4 gig (1024/100*85)

There are 1000 MB in a gig (non binary) so roughly thats a gig used every 2 weeks so 870gig *2=1740 weeks or 33.4 years.

Your ok for space at the moment

Hi Skers5xs, welcome to the Seven Forums.

You got the idea, I see. Question 1 is simple: 1 TB = 1024 GB, so 0.85 * 1024 = 870.4. You should use maximum of 870 GB of that hard disk.

The second question: if it is a direct follow up of question 1, then divide 870 GB (1 GB = 1024 MB so 870 GB = 890,880 MB) with 500 MB > 890,880 / 500 = 1,781.76, so you'd need 1,781.76 weeks to fill that space (about 34 years).

If the second question means how long to fill the complete 1 TB, then it is 1,048,676 MB divided with 500 ( 1 TB = 1024 GB = 1,048,676 MB), so 1,048,676 / 500 = 2,097.152. Filling 1 TB hd takes in this case 2,097.152 weeks (about 40 years)

And if you're my age, you have more HD space than years left. I have 3TB total, so I better get busy if I want to fill them up.

A Couple of RAM Questions

A couple of questions!
1. Fan During my build, I accidentally pulled the fan wires from from the (molex?) connector. When making contact in the right way, the wires are still able to make the fan spin so I know it is definitely salvageable. May anyone suggest a way to fix this, or at least keep the wires in contact with...

Hello. As you can see I'm new to these forums, and I have a few questions. I'm certain they have been asked before, but I reckon it's faster to just ask them all in the same place. I hope you guys don't mind. First of all: I have created a custom themepack based on the game Battle Forge. This...
