I have a file that while being copied between drives will stop with error -36.

I checked the all disks with Disk Utility and its fine.

What tool would you suggest for *file level* recovery? Most tools seem to be nothing more than a UnDelete.

TIA

You don't have any backup? Someone on another forum said that getting an error -36 from a hard drive copy indicates the source drive may have a serious problem.

Out of 13,083 files this is the only one that would not copy over to the new volume.

Isn't there a bit level copy via Terminal?

dd bs=512 if=/PATH_TO_READ_FILE/READ_FILENAME of=/PATH_TO_OUTPUT_FILE/OUTPUT_FILENAME conv=noerror,sync

To help those who need to recover just a file because it won't copy thru Finder. I tried "dd" with and without the "sync" option. Without it the file .m4v would stop playing after a certain point. With sync the file played all the way thru.

dd has many uses. To learn more about dd open terminal and enter "man dd" Hope this helps!
