HDD In PSP

anyone know of a way to install a HDD into a PSP and how??
sorry if i sound like a noobb..

i dony hard mod my psp (and i dont think i ever will tooooo risky) if u were gonna put a hardrive in i`d advise paying someone that knows what there doing or wait till the 4 & 8 gig cards come out (but they arent compatible with any other firmware then 2.7, or just wait till someone enablers em on 1.5) memory cards are better because hardrives use hell of alot more battery

ohh so the HDD goes in where your battery goes and does the place of a HDD and a battery?

i dunno dude neva tryed it
