Adding Garbage Bytes to GCM?

I know this may sound a bit ridiculous of a question, but how can I add garbage bytes to a GCM file so the final file size matches precisely a specified size? If anyone has any idea, please respond right away. And if this post is considered a violation of the forum rules, I apologize in advance.

I dont think you can if you have already wiped the garbage data

I don't know, why you want to do this!?! But try the following thing: open the gcm with isobuster (it works) and at a file (like garbage.bin) with has the size of the missing data. but why you want to do that?

It can't be done, not to match the original ripped image anyway! As to why you would want to do this is beyond me.....

Open it in a hex editor and pad the end of the file with 00 or something. There's no way you're going to be able to restore the original garbage data, though.
