If you're downloading pirated content on the PS3 it is most likely recognizing it as a file it isn't supposed to run and call corrupt. If you install homebrew on a memory card and put it on a PSP that doesn't have custom firmware, for instance, all homebrew files will be detected as corrupt.
It's hard to understand your problem, to be honest, and using all capital letters makes some people think you're shouting or otherwise consider it rude so make sure to post like I am next time
