Hello ....



This is my first post to this thread.I want to copy a hard disk partition into another partition. My source and destination partitions are of NTFs and same size. For that purpose first I did by copying all sectors and it is working, But I wanna copy only used sectors…
Then I find the used clusters by reading the FSCTL_VOLUME_BITMAP. But this one also a slow one ..I want to get better speed. And I tried to get the used clusters by using the FSCTL_GET_RETEIVAL_POINTER also.

At last I tried the windows API CopyFile() also…But everything gives a slow performance…

I have used the 3rd party software”Acronis disk director “,They do this copy partition very fast…

How can Do the copy partition with better performance…

Any idea …..??

Please give any suggestions..

Any useful links to………………… new copy algorithms or White papers…


If this one is not a suitable forum for this kind of questions .... tell me without any hesitation....
