too fast cleanup after try and decide

The issue is the following.
I have used logical disk E as a storage for Try and decide. I declined the changes successfully. After it I tried to use Acronis System cleanup utitilty to clean free space on this partition. But the cleanup works only few seconds and informs it was complemeted successfully. All the other logical disks are cleaned normally. I used scandisk Windows utility. Some errors connected with free space were corrected, but it did not affect cleanup utility performance. I want to be that cleanup utility works. So, please write me on how to solve the problem.
I use Acronis True True Image home 2010 build 7046. There are no bad sectors on the logical disk.

Regards,

Alexander
