my disc is also readable in osx on 10.4.1 -- the one that "failed" so i think u are right that
its the "lead out" finishing that is screwing upi think maybe its because toast 5 was programmed to record to DVD-RAM not DVD+R or DVD-R ****wrong.. below i found an article saying DVD-R + DVD-RW are supported by toast 5 100%
i cant believe i never understood this........ it seems to me that we have been fooled. DVD-RAM seems to be superior in many ways to DVD+R & DVD-R!!
the fact that it writes slow (1x-4x) is ok when u realize that its basically an optical hard drive...that can be overwritten + rewritten...and reads almost as fast as a real hard drive (22mb/s)
its basically a reusable optical hard drive!
now im looking up the difference between dvd-ram + rewritables..
i just put a dvd+r RW into the g4... and tried to go to "recorder" -> "Erase" and it gave me the msg
"only CD-RW + DVD-RW can be erased" so not sure if that means toast only supports "DVD-R RW"(not "DVD+R RW")
or if its the sony drive itself that doesnt support erasing on "DVD+R RW" media
this shit is so confusing
i just looked thru all my binders i cant find a single DVD-R RW all of the rewritable discs i have ever had are all DVD+R RW
wow i was able to find 2 discs.. out of hundreds LOL
DVD-R RW has more of a silver metallic look on the data side...
trying to erase with toast 5 / mac os 9..
its working! its allowing me to erase the disc..
taking a long ass time tho
SUCCESS!
the DVD-RW disc was erased sucessfuly..
it took about 20-25min but its erased.. 4.7gb of freespace
heres what else i learned..
my sony dl drive.. it isnt seen as being capable of DVD-RAM by toast or Drive setup
drivesetup sees it as a 'DVD-ROM'
upon replacing the old LG(made by hitachi "HL") dvd "multi-drive"
when i booted into os9 it asked me if i wanted to initialize the dvd
but drive setup itself.. when i go into see if i can initialize the DVD-RW disc..
instead of saying "cannot initialize read-only blah blah" that it said with the sony drive
now it says "cannot initialize a disk in an unsupported drive"
so this is strange because like i said the os gave me a window asking me to do it when it saw the disc in the drive
as i booted up.. i guess i will reboot + see if i can initialize this DVD-RW disc that i just erased..
the only formatting options it gives me is "mac os standard" or "prodos"
and then it tells me the disc is locked... probably because of the "unsupported drive"
maybe its to do with drive setup version?
http://macos9lives.com/smforum/index.php?topic=1826.msg9291#msg9291 this post i quoted somethign about initializing disks with drive setup
but thats for dvd-ram discs not dvd-rw..
i dunno. i give up for now;)
