How to recover the lost data from hard disk ?
Q. I have lost some data in hard disk and I have successfully processed the data recovery, now I am copying the lost files to my hard disk in "Drive E" but I am receiving the message "The destination path you have selected is on the source partition. Please select a different destination"
Please Help Me, How Can I Recover It ???

A. OK, so I have done this using a commercial recovery package. Your problem is you are trying to put the recovered data onto the same physical disk as it is coming from. My program will only READ from the damaged drive, and must recover the data to another physical drive, NOT a different partition on the same drive AND the destination must have a larger physical capacity as the damaged drive AND enough free space for the entire contents. The reason is the extreme low level on which the drive is being accessed. The OS is literally digging into the hardware and managing the electronics by brute force. What I ended up doing was adding a 2nd new blank drive to my desktop and the damaged drive as the 3rd drive. I did not have enough room on the C: drive so I needed a D: drive to receive the image of the damaged data. The E: drive was the damaged one. After I recovered the image file, I was then able to "mount" the image as a virtual drive and copy files from it to my C: drive. The key is this: I needed a space large enough for ALL of the data on the damaged drive, not just for a few files. It took me a while to figure this out as the documentation was not clear that I first had to recover the whole disk image, before I could access individual files from the image. I got the same type of error as you did because on my C: drive, there was not enough room for the entire image file, hence the new empty disk as the target for the recovery. Followed by copying a few files from the recovered image. You MAY have the same kind of problem. Make sure the destination has enough free space and is NOT on the same physical drive as the damaged data.
