Windows 7: HDD free space lost in Space....

Hi

My laptop has 2x 7,200RMP ~320 GB hardrives. Previously I was using Vista and all partitions were devided equally (~150 GB) . After I've installed Windows 7 on C, part. D (which also has recovery files) suddenly became 13 GB,whilst other ones stayed the same.
So my question is where did the other 135 GB go ?

Thx in advance

Try posting a screen shot of disk mgmt so we can give a more accurate answer.

Here it is
Btw just found out that it's physically there, but not shown nor named. How come so ?http://www.freeimagehosting.net/imag...912d061e3b.jpg

There's nothing missing, although you do have one partition that doesn't have a drive letter assigned to it. Right click on the the first partition of drive 1 and select "Change drive letters and path" in order to make it available to windows

That's just the prob, nothing (except Delete & Help) is available in the menu.

Try formatting the partition as NTFS from disk management first
If that doesnt work you will have to do it via elevated command prompt:
type cmd from the start menu > right click and select run as administrator
in the command window type the following one at a time and press enter after each command:

diskpart
sel disk 1
sel par 1
format /fs:ntfs /q
assign
exit

That should solve your problem

Still nothing : "No volume given. Please select a volume and try again"

try it again as posted now.. I edited my last post after I noticed the partition wasn't formatted
otherwise type

list vol
sel vol (the one that has no drive letter assigned)
assign

Tried formating: but says: "Argument invalid"
Second option didn't work either, cuze this partition isn't even listed.

That's strange because if it's listed in disk management, you should be able to right click on the partition to format it, then assign a drive letter. At this point I am out of ideas
