    Anyone ever see a game pass MD5 but fail a SHA1 check? For some reason CSI: Hard Evidence is for me. Should I be leery of running it? I hate to think the disc is bad. :/

    what do you mean by "pass MD5"?
    There isn't a public MD5 database for Wii games to compare with.
    Sha-1 is build into Wii games, if it fails, its most probably bad. No harm running it though it may just crap out at some point or it may not if you are lucky. Of course it is recommended to use a good one.

    I know that. But Wii Backup Manager has MD5 and Sh1 error checking. If the hash is there, you have a option to check it. I did and MD5 says no problem, but I get error with SHA1.

    Didn't think it would do any harm other than crash but wanted to check. Guess I will try to find another disc or an image somewhere.

    Wii Backup Manager can't verify a game is good by checking MD5.
    It just store the MD5 when you first "verify" the game's MD5. If subsequent "verify" matches that stored value, it is "good"

    You can check the log and it will tell you the truth if you just made your game's first MD5 check recently

    Hmm I have tried to "verify" games that didn't have the MD5 hash and it didn't do anything. I assumed that some backuploaders add it when you dump the game, and some don't. I've used a few different ones so I assumed that is why some of mine do, and others didn't.

    from http://www.wiibackupmanager.co.uk/home.html

    "An MD5 Hash is calculated and stored in each disc transferred to a drive, so it's possible to verify the data integrity at a later date. The hash isn't calculated for ISO yet."

    Have you played the game at all? If something is wrong with it, yes it could stop working sometime during game play, but most likely it'll either load or not and if it loads it's probably a good copy.

    It's not a big deal, not like if it doesn't work it'll hurt your system. I say just load her up and have fun with the game instead of obsessing about the hash check.

    If the sha-1 verify failed, the game is most probably corrupted somewhere and depending on where the corruption is, it can show all kinds of symptoms - from not loading, hang halfway to corrupt your save file when you almost finish the game.

    Yes if you haven't verify the game, you can try your luck and its harmless in most cases. But if you had verified the game is bad, then why try your luck if you can "re-rip" the game.

    I did for a bit but that was a while ago. I was checking over the games since I am moving everything to a better HD and came across this oddity. Everything else checked out, this was the only one that didn't, and like I said passing the MD5 and not the SHA1 really made me scratch my head. But now I see MD5 can vary and the SHA1 is a real indicator if the image is good or not.

    I agree. I just hope my disc isn't bad and that was the reason for the fail. Again that is why I was asking if anyone else had ever seen this before and wondering why the two checks could disagree. Now I know.
