1tb HDD only shows 523gb

There is definitely something wrong with the control info on this drive - possibly in the MFT. You do not just loose nearly half a terabyte like this.

The problem is, that working on this C partition can result in total loss. It would therefore be imparitive to make an image of the partition before we get started. Do you have an external drive large enough to place all that data - seems to be like around 400GBs worth. If we can do that, then we could proceed.

i could possibly send some of it over the network to my fathers pc and save some of it there well aleast some of the important stuff, im going to have to wipe my hdd aint i

Try this: Open a command window with administrative privileges. Then type diskpart.

Once DiskPart is ready, type list disk to identify your harddisk by its number (we'll assume it's 0, though it may be different. If so, use that number for the following commands accordingly.)

Type select disk 0. Now follow up with list partition and, as before, select the C: drive by typing select partition 1. (Another way to do this is with list volume and select volume <number>).

Here comes the clou. Now type extend filesystem. What this command will do specificially is to check the size of the partition, and match the size of the NTFS filesystem to it. This is very useful if a partition was resized without correctly adjusting the filesystem as well.

This command should only take a moment to execute and is completely safe (and yes, it also works on the running Windows system). When finished, exit DiskPart with exit and then close the command window.

Now check the size of your C: drive again in Explorer. Did it work?

no sadly think i'm going to have to wipe the whole hdd :/ still says 523gb in iexplorer

Well, best would be if you made an image. But for that you would need an external disk with at least 250GB of free space. Next best is if you save all your user files to somewhere.

I think you are right. It will come down to reformatting the disk and reloading everything. With an image that would be easiest. But if you can salvage your data, reinstalling the system is no rocket science either - just tedious because of all the updates you will get. And then you also have to reinstall all our programs.

Let us know how you would like to proceed. I will close down for the day but be back tomorrow in case you need help with some loose ends.

PS: Just saw what Corazon posted. It is worth a try. This is an old Server 2003 command. Let's hope it does not muck things up. Backup your user files first.

ye i just hate the idea of having to update all my programs takeing up the net and my games like bfbc2 which last time took around 2hours to update since it was over a year of updates :/

Have you tried the steps in my previous post? Please post back with the results after using diskpart.

That fixed it thank you very much dont have to reformat now

Awesome! I'm really glad that did the trick for you and you don't have to reformat now.
