Just remember that even when files are deleted, they are still there! A delete only removes the Master File Table (MFT) entries, not the files themselves. Superior file recovery software can usually recreate the entries if that was the case. Finally, I suspect that just one file was corrupted which would then hang the LR copy process. Once the files are recovered on the Delkin card, try copying the files manually with Windows file explorer, one by one, until you find the corrupt file. It might take awhile but you will be more successful for the effort.
