I have Diskeeper 2010 Pro Premier x64bit version and I installed it on my Windows 7 Ultimate x64.
I'm having a problem using manual defragmentation.
I have two partitions: C:\ (100GB) and D:\ (197GB) and I can analyze both of them but when I try to run manual defragmentation of any of them I get this error message:
"The defragment operation you requested failed to start on volume (C: ). For more information refer to the Diskeeper Help and Windows Event Log"
Same is for D:\ partition.
Also, I asked some of my friends and colleagues and they also have the same problem.
Can you please help me?
Thank you on your time.
