Hugh # of rars - need to repair last ones only

[sandage_2000]

I have file with 436 rar parts and all are good until I get to 432 which I can't get to download completely even with 10 attempts.  Is there anyway I can just start checking and repairing at a specific number without having to wait the "eons" for it to check all of the first 426 files and just start with #427 to end files to check and repair the one bad file?  I have all of the par fix-it files needed already downloaded.
 
Thanks

No, that's not possible. The rar files belong to an integral set which has to be checked completely. The available par2 block are created for the complete set as well. So the only solution is to wait while the complete set is checked...
