GUnite version 3.0.2 once show invalid piece when unite pieces for my VERY IMPORTANT data

I have used Gsplit 3.0.2 for several times, and everything goes well. Last week I try to split two .7z files and unfortunately, one of them cannot be united again, here is the warning info​

Warning: invalid piece​

The selected file does not match; this is not the requested piece number 2.

D:\PhantomWork\phantomwork\disk2.gsd

Choose Retry to select another file, Abort to cancel or Ignore to skip this piece file (the restored file will be incomplete in this case).

and the log printed here

To be detailed, there are 3 pieces
Welcome to this program. It will restore the following file:

3 piece files are required.

Select where you would like to place the restored file
and press Unite to continue.


Best Regards.

Try the GUnite software that is shipped with GSplit. It can give you more details about the error.
But it’s possible that the second piece file is incorrect if GSplit tells you so (could you have mixed two different piece sets?).

There maybe a chance that I mixed the files, but why should the other pieces get united successfully? The two disk2.gsd files from two file sets are not the same at all. What’s more, can I still recover some of my data from the seemed broken pieces, for there is something important to me to get them partially back.
Thank you.

It’s possible that only disk2.gsd got overwritten. You can inspect the faulty piece with the Piece Inspector tool of GSplit. You’ll see what is wrong.

no more info here. But the first and third piece show meaningful messages. So there is nothing I can do to recovery anything?

any suggestions? please

Try GUnite. It will let you bypass the 2nde missing piece file.

but I can’t unzip the united file using 7z anymore that way

can you help me?

You should then look into a 7Zip repair solution. Unfortunately, GSplit can’t recreate data that is lost or overwritten by error. You can partially reunite your 7Z archive and try to extract data from it. Some software can try to repair damaged 7z archives but GSplit doesn’t.
