holy crap, there are only usb and SATA in the shops, no firewire and PATA.
u are joking about this right? its been this way since about 2008.. only the last 6-7 years.. have u been sleeping ?
firewire (Fw400) has been dissappearing off the face of the earth the last 4 years and now the same is true about fw800 too
for the last 2 years..
its no big deal, just buy a 3$ sata to pata adapter, buy a new sata burner + there u go
u can use practically any burner with a g4
it would be more difficult to find one that ISNT compatible
