I found a firmware that supposedly would make the original superdrive (1x) of my titanium G4 powerbook (15", bought Jan 03) faster (become 2x, see http://superdrive.cynikal.net/).
so I updated my firmware using first "UJ-815 to DWDB", then "UJ-815 to DOCB" and the computer boots up and seemed to worked fine.
Then I connected my 40 gig firewire drive and it reported "mac os cannot read this disk, do you want to format/ignore", clicking ignore the disk mounts but cannot be written into and read (icon spins and computer gets stuck). I tried a 160 gig external firewire drive, no message at all.
I tried a few more times with the 40 gig and the message appeared twice but became readable... the problem is my 160 gig seems to be dead! it cannot read by my iMac G5 or my G3 B/W. Disk utility does not see it. I wonder why my mac would kill one and not the other. I have had no problems with either Mac with these two drives. Glad that I only backed some data recently from the 160 gig.
It appears that I followed some wrong directions (on a different page), changed the firmware to a 17" one (DWDB), then flashed the original apple firwware back (DOCB)... but it does not explain the mess up of firewire. Now I flashed the correct firmware (firmware_uj815_D101). however even the 40 gig external firewire drive stopped working...
My powerbook g4 has OS X 10.2.8. and G5 has 10.3.
Thanks.
