You should not copy the bad files. The raidfile library will drop  
back to recovery mode when a file is not present or it gets a read  
error from the OS. If you copy corrupt files to the new disc, it will  
not detect the problem as there is no read error, and you will get  
bad data back.

Note you cannot recreate a lost drive. If a drive dies, you can use  
the store for reading but not writing. I plan to remove raidfile  
support in the next major version -- software RAID support is much  
better these days, and the raidfile support is not complete as it  
doesn't have full recovery options.
