is HDLoader safe in my PS2

I think it is safe 'cause I've seen some of the PS2 shops at malls having all their consoles modified into like that. You just have to make sure the hard disk that your going to get for your console is compatible and in case that you really want to be sure, have a certified technician do the modification so you'd have a receipt and could comeback anytime when it chokes up or something. HDLodaer is quite convenient since you don't have to use the disk tray that has the lens too much. You just have to load the game into the hard disk and depending on how large the memory space of your hard disk would be the amoun of game titles you could fit in. Kind'a reminds me of these "in one" cartridges during the famicom era. As much as I could say. It is safe. In case your doubtful, you could look online soureces for complaints about it.
