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!

That's actually useful, I would have needed this in the past. Thx.
