partition: get back size/space
R. Rajesh Jeba Anbiah
Instead of allotting 10GB to C, 15GB to D and 15GB to E drives
respectively, he allotted 10,000MB and etc and there by missed some
spaces (around 2GB).
Could I get back those spaces?
I have also googled
<http://groups.google.com/groups?q=increase+partition+size>. Most of
the links suggest Partition Magic; but, as far as I understand it
doesn't fit for this issue, it can only be used for resizing the
partitioning.
Any help is much appreciated. TIA

Try a new search for "partition merge". I'm sure you will find some software

Keep in mind that when a manufacturer says that the hard drive
size is 40 GB what they mean is that it can store
40,000,000,000 bytes. That means that your drives real capacity
is 37.25 GB. If the person who partitioned your hard drive
started by making C 10,000 MB and D 15,000 MB they would only
have 13,147 MB left for your E drive.
If Windows has been installed on this drive, go into Disk
Management (Start -> Run -> diskmgmt.msc). Check the size of
the HD. Is it 37.25 GB? If I've done the math correctly the C
drive should be 9.77 GB, D drive 14.65 GB and E 12.84 GB. There
shouldn't be any unallocated space.
Take a look at this article for more info:
Why is my drive displaying a smaller than expected capacity
than the indicated size on the drive label?

Many thanks for the deep insight. Much appreciated indeed.

Will check this once I get home. Thanks again.

Thanks, started googling.

Does Disk Management (Start - Run - DISKMGMT.MSC) actually show some
unallocate space on the hard drive? Or is it fully allocated to the
existing partition with nothing listed as unallocated?
If there is unallocated space then you can use a partitioning utility
such as Partition Magic or BootItNG (www.bootitng.com) to adjust the
size of the existing partitions so as to incorporate this space. Note
that space can only be added to the adjacent partition. So if there
is unallocated space between C & D then it can added to either of
these drives (or some to each) but not to drive E:. Similarly if the
unallocated space is at the end of drive, after drive E:, then it can
only be added to drive E:. However these partitioning utilities have
options by which you can "slide" a partition so as to change the
location of the unused space, and then add the relocated unused space.
Or you can create an additional partition to use the unused space.
DISKMGMT can do this for you without destroying the contents of the
existing partitions.

I just checked in my system, not exactly as you guessed. It's little
crazy as even the top to bottom panel values differ. Here is the full
details:
diskmgmt.msc
~~~~~~~~~~~~
Top panel:
---------
C: 9.31 GB FAT32
D: 13.96 GB FAT32
E: 13.97 GB FAT32
Bottom panel:
------------
Disk 0: Basic 37.27 GB Online
C: 9.32 GB FAT32
D: 13.97 GB FAT32
E: 13.98 GB FAT32
C drive is colorized as Primary partition
D & E drives are colorized as Extended partition and Logical drive
****Note: Note the difference between top & bottom panel (exactly 0.01
GB difference)
Properties->Volumes on "Disk 0" of bottom pane:
----------------------------------------------
Disk: Disk 0
...
Partition style: Master Boot Record (MBR)
Capacity: 38162 MB
Unallocated space: 0 MB
Reserved space: 0 MB
Volumes:
C: 9539 MB
D: 14308 MB
E: 14315 MB
My Computer:
~~~~~~~~~~~
C: 9,992,126,464 bytes 9.30 GB
D: 14,988,222,464 bytes 13.9 GB
E: 14,995,955,712 bytes 13.9 GB
****Note: bytest to GB is not rounded off; but truncated

It doesn't show any unallocate space (or I didn't/couldn't notice).
I have also posted a full details of my system at
<news:1140876491.7...@u72g2000cwu.googlegroups.com> (
http://groups.google.com/group/microsoft.public.windowsxp.perform_maintain/msg/cded15d925ece71f?
) There is some funny differences in the calculation. But, I guess
there is no space wasted as I'd thought before.

Many thanks for your much valuable comments.

The bottom line to all the numbers is that you have no
unallocated hard drive space.
The numbers I put together were based on creating partitions
that were 10,000 MB and 15,000 MB. Turns out that the person
who setup your hard drive based their partitioning on bytes, 10
Billion bytes for C, 15 Billion each for D and E. That's why my
figures are different.
The discrepancy you see in the top and bottom panes of Disk
Management is not unusual when your drives are formatted FAT32.
I don't know exactly why it happens. It may be that Windows
reserves a small area in case the drives are converted to NTFS
at some point in time. After conversion, the two numbers agree.
Take a look at the numbers listed for the F drive in these
screen shots of Disk Management that were taken before and
after converting the drive to NTFS:
Disk Management with FAT32 drive
http://home.comcast.net/~nepats99/DISKMGMT1.html
Disk Management with NTFS drive
http://home.comcast.net/~nepats99/DISKMGMT2.htm
FYI, if you decide to convert any of your drives to NTFS, take
a look at this article so that you don't end up with 512K
