Hi Miguel, the checksums are not really used at this time for anything else than the checksum checker ([dspace]/bin/dspace checker), so you could simply ignore that. But you could also update them in the database. The algorithm is md5, so you can run md5sum on the file and update the result in the "checksum" column of the "bitstream" table. It should be easy because you can look up the row by the file name, which is stored in the "internal_id" column. So it would work like in the following example (for each file): UPDATE bitstream SET checksum = 'efa087dc65899242bae4ecda7ae33e04' WHERE internal_id = '132179613084212233373659715100737882009'; Regards, ~~helix84 Compulsory reading: DSpace Mailing List Etiquette https://wiki.duraspace.org/display/DSPACE/Mailing+List+Etiquette ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
