I think you guys are being a bit harsh on Guilio, he has brough to our attention that there is something within the whole backup + inject method, i think he should be appreciated for his work, every little helps! And to everyone slating him, there is no need, you were all supporting him when you thought a ps3 hack was just around the corner yet some guy calls him a fake and everyone is against him.
Certainly there's no way that copying files *in a specific order* to the HDD can make any difference. PS3 OS reads FAT32 volumes just like any other.. it looks for names. It doesn't look at the age of any entry in the directory table to determine the correct file to read.
Sure, Guilio has identified something.. that if you corrupt your backup files, you can end up with broken icons in the XMB. Whether this side-effect could lead anywhere is a mystery, but for now it's sounding pretty weak.
