I shoot weddings and events. January had some hectic shooting assignments. On 25th I brought a new 1TB hard drive. End January I had to shoot 2 weddings and other events, just downloaded the photos to the new hard drive and did not bother to have a second copy (which I usually do) never imagining the new hard drive could give trouble in such a short time.
on Feb 3rd when I tried to connect the hard drive to my computer for backing up the files, to my horror it was not responding. None of my 3 pc's or laptop could sense it. A software friend tried to change the chip and recover files using a recovery software. All he could get was most of the jpegs and a lot of tiff files. The hard drive had CR2 files which the software turned into tiff files and they were not opening.
The following days I tried to recover the raw files with a handful other recovering softwares which had CR2 support but none could do it. Even though some managed to salvage some files, but they were not opening.
Finally, my brother offered to try. He tried with Diskinternals Partition Recovery. After a operation lasting for 52 hours the software managed to recover all the CR2 files totalling 5252 files and out of it only 2 are corrupted and also as a bonus it recovered full size jpegs of all the 5252 files by itself. I am eternally thankful to Diskinternals.
I lost a video 2 years back by deleting and overwriting the card before copying. I could not recover it and lost a lot of credibility in the field. I know the pain of losing files. I am posting this just incase some one in similar position may find it useful.
