drives and space

GD4E1 · 22 Mar 2015

Is there any way to calculate the amount of free space that would be available for a given partition/drive size and vice versa?
for example, if I was creating a partition and I wanted the available space to be 500 MB, what physical size partition would it need. As you're no doubt aware, a 500 MB sized partition would give something like 450 MB due to various system files, therefore is there an algorithm or something that can be used to calculate the required partition size to get 500 MB free space on a partition?
Thank you

With what degree of accuracy?

Multiplying by 1.074 will usually be close.

If you want 500 usable, then 1.074 multiplied by 500 is 537, which would get you close.

There's a more accurate way, but I haven't committed it to memory or looked it up.

I personally don't like to squeeze the drive space that close.
You will always need some elbow room to do things like defrag ect.

I know the partition that has Windows 7 wants about 10% free space or a little more to work properly.

This is not a operating system drive so I probably won't be using defrag often, files go on and are unlikely to be moved or deleted, I would prefer a overshoot to an undershoot (so 501 would definitely be preferable to 498, for example), I shall try the 1.074 method and see what I get, thank you for your help

On a side note, although this probably isn't the place, how do I reduce the number of times windows 8 goes blue screen of death? It's happened twice in the past half hour and every time it does, I have to restart the thing I was doing. Is it to do with defragmentation or misaligned core files, for example

Thanks again for your help

You just make a partition in the size you want, you`ll never know what size files are gonna take up on it and why care.

Blue screens could be caused by a number of things, hardware, drivers etc. Best thing to do if it bothers you, if you don`t have restore points or you never created a system image, is to re install windows, it usually cures all your problems :)

Thank you for your help, I will wait on Windows 10 and if that isn't much better, attempt a clean install. Never had the BSOD problem (or really any kind of problem) in windows 7 ultimate though...

I don't know if it's appropriate to post for help in the Seven forums BSOD forum for a Windows 8 BSOD ?
