[Zope] Disaster Recovery of the ZODB

Hi.. I just uploaded many files with load_site (thanks Itamar!), but I ran out of disk space while doing this. Seems as the last transaction corrupted the Database seriously. When I try to delete the folder where the errors are I get: Error Type: CorruptedDataError Error Value: The same with packing database. And when invoking Undo, i get something like: long int too long to convert Any ideas what I could do to repair my database and deelete the corrupted folders and start over again? Thanks in advance, Mario
