Ps3 Hdd Loader For Ps2 Playing PS2 On PS3 HDD?

Playing PS2 on PS3 HDD? - ps3 hdd loader for ps2

Hello. I did not support a 80 GB PS3 (). When reading the PSN, I came to the PS2 hard drive add-on. I wonder if in addition to suffering from "not compatible", I could play compatible with the drive? It could also HD Loader?
Thank you in advance.
