Are you sure that the disk has no data on than 900 GB available?  If there are still files, that may cause a problem.

Yes, No Data in it. It is a new installation of windows 7. I tried disk clean, disk defragmentation & error checking but no avail.
Does your recycle bin have files?

You can use this tool to analyse your drive to figure out where space is being used,

There is a scan button up top.   It'll scan your C drive and you can sort the results by size.    This is the tool and method i use when i need to figure out where space is being used up.

The Windows built-in shrink option can only shrink a certain amount, even if there is lots of space left. Use a 3rd party tool to shrink your partition, for example GParted which is included on the PCRepix LiveDVD:

C Drive has around 900 GB free space. Laptop is brand new with windows 7 installation.

Disable The Paging File

    Right-click Computer
    Select Properties
    Select Advanced system settings
    Select the Advanced tab and then the Performance radio button
    Select the Change box under Virtual memory
    Un-check Automatically manage paging file size for all drives
    Select No paging file, and click the Set button
    Select OK to allow and restart.

Disable Hibernation

    In the Start menu search box, type "cmd" without the quotes
    Right-click the cmd program and select Run as Administrator
    In the command line, type "powercfg -h off", again without the quotes
    Once completed, the command prompt returns.


Then defrag C: once again.

Then retry the shrinking.
um why not just re-install? if it's brand new, use the windows7 disk utilities in setup and create the drive partitions before you even install.

it'll probably be faster and less expensive than finding 3rd party tools.

The problem with the shrink command is that ANY data that resides further down in the partition will stop the shrink from shrinking past that point.  gparted which is free or other 3rd party tools that run outside of the operating system can do this as they will physically move that data to unused areas located closer to the beginning of the partition.

i.e. X is used O is unused locations each location is 1 MB  11MB used 6 MB unused but shrink will only shrink 1 MB

if the data is like
XXXXXXOOOOOO then you can shrink 6 MB.

Agree with R Andrew Koffron 100%, it's definitely faster than downloading anything and also the most stable way to create the operating partition again.
