Disk Management is not displaying correct HDD size. Partition issues?

I recently created an image using Clonezilla using partitions rather than whole disk. I had to do this to apply the image to a 80GB HDD rather from a 250GB HDD. This way my whole disk image would fit on smaller drives. Well I think my shortcut to making a whole new image on the 80GB broke something.

I did this by shrinking the partition on the 250 to ~24GB and making an image of the System Reserved (100MB) and the C drive (~24GB). I then applied this image to an 80GB drive so I would be able to take a whole disk image to apply to any drive that is 80GB and larger.

After I applied the Clonezilla Part-Image to the 80GB the partition was only ~24GB... This is expected. I figured I would be able to expand the partition to the un-formatted space.

The kicker is, I can't do that. Disk Management says that the C drive is actually ~74GB.

My brain hurts. Is there a known solution for this?

What I am going to try next is remove this 80GB HDD, plug it into another computer and delete everything off it. Make it RAW no partitions. Then I will apply the part image again and hope that it will have three partitions. 100MB, ~24GB, ~50GB. The 50GB will be un-partitioned space that I can extend the C drive to. This is my theory and I hope it will work.

I am able to extend the partition if I use a 160GB drive but not the 80GB. This is very strange.

What might have happened is that somehow, during restoring your image to the 80GB HD, the restore process automatically expanded the 24GB partition to fill the whole drive, but not the filesystem. So NTFS would still think it was occupying a 24GB partition when it's really much larger.
It is possible to use diskpart to extend a filesystem "after the fact" to make it fill the partition it's occupying. The command to do this is simply "extend filesystem" at the diskpart prompt (of course you have to select the disk and partition/volume first).

I figured it out.

I took the 80GB drive, manually created the 3 separate partitions. I then imaged the 2 smaller partitions using my original Part-Image which included 2 partitions. Once I was in windows I was able to extend the 24GB partition to the unformatted 50GB partition. Viola.

Thanks for your response. I may try that just for kicks to see if it works.

The best tool for partitioning is free Partition Wizard bootable CD
which will also give you the correct readout if Disk mgmt errs.

Thanks for that tool it is pretty nifty. Turns out I was able to extend the partition but when I make a new full disk image and apply it to a larger drive it leaves un-partitioned space. (Eg. 160GB drive ends up with the 100 Sys Reserve, ~74GB C:\ drive and ~85GB unpartitioned).

I am going to just bite the bullet and make a whole new 80GB image from scratch. It's a pain since we have a laundry list of stuff to install and configure but I gotta do it.

Thanks for all your input guys.
