    Please Explain What's Happining. I'm Copying ISO's from WBFS Drive 1 to WBFS Drive 2

    I've used USB Loader GX to install about 35 of my games onto a 1tb drive. Now I've decided to go to a larger drive (I know it's overkill but I have a 2tb Seagate FreeAgent external that I'm not using for anything else).

    Using Wii Backup Manager v0.3.5 beta 1 I mounted my existing drive as drive 1. Then I formatted the other drive into 2 equal WBFS partitions. I was able to load, and see, each partition, one at a time, as drive 2.

    From what I've read I knew it would take time to copy each game so I figured I'd copy them 5 at at time. When I was finished copying the first 5 games I looked on drive 2, using Wii Backup Manager and found the copies were there.

    There was one thing on drive 2 that wasn't on the drive 1 though, an MD5 Hash for each of the copied games. Looking on drive 1 with Wii Backup Manager the MD5 Hash column was blank (or said something like "None" or Nothing" for each game on the drive). The 5 games I copied to drive 2 showed a Hash number for each one.

    My questions are;

    1. Why isn't there a Hash number for any of the games I copied from the original discs to the drive?

    2. Is there a way to generate the Hash number when I put my games on the hard drive using USB Loader GX? If so please explain how to do it.

    3. Is there a way to put the Hash numbers on my original drive? If so please tell me how to do this too.

    4. Are these numbers really important? Wii Backup Manager gives you an option to compare the copied file to the original but it couldn't do it, according to the log, because of the original not having the Hash numbers.

    I've searched a number of different places, including here, but I haven't been able to find the answers.

    1. I do not know. Googling didn't turn op much either.
    2. No, USB Loader GX has no such option.
    3. I do not know.
    4. Not really, the hash numbers (or md5 checksums as they are also called) tell you wether the content of a file has changed, because changing the content of a file changes it's md5 checksum. For example, if you copy a file and the md5 checksum of the copy and original do not match, you know that the copy process went wrong. The chances of this happening are quite small.

    Thanks for your reply.

    I realize that the chances are small of something fouling up while the ISO is being copied to the second drive, but having a checksum on the original drive would verify if that happened. That's the reason I was hoping there was a way to generate a Hash number for the games when I first install them.

    I guess I could always copy the games to the new drive using the original discs again but I still wouldn't have a Hash number. No big deal...it's something I'll live with.
