Getting a good copy?

Finally I got good copy, well I hope it is, ( I was checking the m5 checksum you shouldn't install any copy that the Checksum is wrong )and I thought why haven't I got a utility that does it. It's really important for a Mageia-like organisation, never sending out CD's and DVD's. Anyway I got a duel CD the 2 days then the UUID was wrong and I couldn't keep my home partition, clean install was the only option. There is always something you haven't backed up.
