Cannot shrink volume, not enough available space when there is?

Hey guys I just went a created an account on here because I have searched for hours and haven't found anything. And everytime it's something to do with people who have exceeded the maximum amount of partitions they can have which is 4. The problem is not this, I have no partitions on the selected drive AT ALL. I have about 105GB free of space and when I try to partition 25GB it says there isn't enough space available when there is! For some reason though I can get up to like 18GB and it works but if I go over that it just says no space?

I really do hope someone can solve this problem asap. This drive is not my system drive, it's an extra I have in my pc and I run my OS on an SSD and have tried using 3rd party programs and have had no luck.

Thank you for reading and hopefully I could get some much needed help.

No, I have never had errors or the drive breaking and yesterday I did run tests to see if the drive was working okay and it was. I can copy over sata just fine, it's like it can get so far and then just stops working. I tried doing that resize again with the program got up to 14GB then it crashed again with the same error code.

Oh and sorry, I have a western digital caviar green 750GB and it is drive E.
