How to recover files from windows backup tool with Invalid MediaID.bin?

I have a backup from 2009 with the extension .wbcat and after I opened windows 7 backup and recovery tool and selected the folder that contained this backup, there was the error: "Invalid MediaID.bin"

I tried to extract all the files with winrar using Extract here in hope that it would join split files. However, there were several errors and I discovered that the errors were from the split files.

However, it's not possible to join them using winrar, or at least, I don't know how. I put a note with every number of part that had an error:

145 146 147 149 151 152 155 156 158 160 163 164 167 168 172 175 176 180 186 187 191 192 194 199 200 203 204 209 214 217 218 221 222 228

How can I join these files? They have all the same name. Example: one of the parts has

part03.zip : file1.avi (200MB); file1.avi (10KB) part04.zip : file1.avi (200MB); file1.avi (30KB)

So this is how I solved the problem:

Opened an excel and looked at every part number near the ones with error, despite not having an error.

Example: if part03 has error, then lets see what is there on part02 and part01. It turns out, they can have parts of the file.

Therefore, I did something like:

Then, extract each folder and each file, they must be different. Winrar will try to substitute files like example.AVI (200 MB) and example.AVI (10KB), however, you must make sure they are extracted and rename them adding .0x to the extension and x being the number of the file.

After this process and extracting part02, 03 and 04 we can have something like:

example.AVI.01; example.AVI.02; example.AVI.03; example.AVI.04; example.AVI.05

Now lets join them using cmd.

Change the directory to your folder, example:

cd c:\test

And now lets join them using

copy /b example.AVI.01+example.AVI.02+example.AVI.03+example.AVI.04+example.AVI.05 example.AVI

Now we have our final file called example.AVI.
