Building File List Failed

Hi everybody i'm using windows 7 ultimate sp1 32bit and i have 2 hard disks. One wd aaks partitioned to two pieces (one for windows , the other for data) and one samsung only for data.

The aaks windows partion can be defragged fine but the other data partion and the samsung hard drive can't be defragged.

Any help please ?

i've just found that when i uninstall "folder lock 5.9.5" everything works.

hope you 'll find a way to solve this problem as i would like to keep both programmes.

edit: both programmes work fine in my laptop!!!! strange things are happening here.
