Does anyone know if there is a way to recover the files that have been transferred with Nikon transfer 1.5.3 and shows up as low res files? The files actually are 40 mb files but display as low res. Unfortunately I deleted them from memory card before I noticed and the memory card was overwritten with new pics. Thanks for your help. I have now removed the old Nikon transfer from all of my laptops.
I will only speak to the memory card here in the event that you have not "overwritten" all of the files so far.
I use a piece of software called "Zero Assumption Recovery" It has saved me a few times and was abe to get images off sd cards that I thought were overwritten or formated. I am hopful that someone else can help you with the transferred files part of your queston.
Are you able to convert the files to high-res images?
The NEF contains an embedded jpeg used for preview. It's possible Transfer did something so that embedded jpeg renders low-res, but if the raw data is still there, a raw converter will still operate on that data. Try different raw converters if Nikon's gives you trouble.
Formatting a card does not actually erase data, it just clears the table which tells which files are on the card i.e. the images are still there. Data recovery tools will be able to recover images from a formatted card, but if you've recorded any new images on the card, you will not be able to recover whatever was overwritten in that action.
I am not able to convert files to high res files either in Jpg or raw. The files cannot be opened by any other software including ps , lightroom etc. I am working with Nikon to see if they have suggestions
If one checks Bill Claff\'s Home Page and looks for the post about the previous corruptions, you might have a lead about the current situation, but the corrupted bits and bytes might have changed. It does give you an idea about about how to fix the problem.
The real solution is to create a work flow that creates a backup of the images only using the OS's cut an paste operations and an external card reader and possibly a file compare routine to verify the transfer was done without any corruption. Do not allow the media card to be erased or reformatted after transfer. Then perform your transfer for your regular work flow. And only after you are satisfied that there were no errors, then reformat the media card. Do not allow the media card to erased or reformatted after transfer.
Notice there is no mention of Nikon Transfer. Version 6.2.5 and version 6.2.7 both had bugs. Enough said.
Even large computer systems with automated backup software have and continue to produce bad backups because there is no verification that the backup was complete and without error. In many cases this could easily be determined by looking at the backup log.
