Resizing a partition on an external hard drive

Hello, I have a problem resizing NTFS partitions on my external hard drive. First I tried to shrink one of the partitions using the Disk Manager utility in Windows 7 (I thought that I can resize the other one to the unallocated space using the 'expand' functionality), and later also tried EASEUS Partition Master. Both seem to have trouble with the first step, which is reduction of the space on the first partition (700 GB -> 250 GB), as both programs simply get stuck. (I let it run for 4 hours before giving up). I also tried runnig checkdisk to see if some sectors of the partition are not damaged, but it didn't help. I would really appreciate any hint as to how to solve this problem, or a recommendation about which alternative software to try. Thank you.

I will try the Partition Wizard, thank you. Here is the screen shot.

I want to enlarge the partition Ext2 (I: drive) by first shrinking the size of the partition External (H: drive).

As far as i can remember ( im 99% sure) you can only expan to the right,so H will have to be on the right.
Also,when using Partition Wizard,after each task, always click apply for it to take effect.

Yes, I now know that the Disc Management utility can't do what I need, but I expected it to at least shrink the H: partition.

Yes, it did. Thank you very much!
