• Do old PowerBook G4 (1 Ghz) have problems reading huge files like a 2.54 GB DMG that I burned to a DVD+RL?

    Hello.

    Do old PowerBook G4 (1 Ghz) have problems reading huge files like a 2.54
    GB DMG that I burned to a DVD+RL? Finder says -- size and can't open it (damaged file). However, a 2012 13.3" MacBook Pro's mac OS Mojave
    v10.14.6 had no problems reading and opening it.

    Thank you for reading and hopefully answering. :)

    none whatsoever, however, the optical drive could be failing and/or the

    Yeah, it looks like this PB G4's internal original Matshita DVD-R UJ-815
    drive is going bad since it has problems reading. But then MacBook Pro's internal drive and my decade old 64-bit W7 HPE SP1 PC's internal Optiarc
    DVD RW AD-78220S drive had no problems. Can PB GB4's internal drive read burned (Memorex) DL DVD+Rs well?

    of course, although the disc itself deteriorates, and at some point, it
    won't be readable anymore.

    Some old drives do have issues with burnt disks. For example, some old
    drives don't work with rewritable discs, but will with single-use
    recordable discs, then there are even older drives that won't work with recordable discs either, and only work with proper factory-pressed
    discs.

    The dual-layer could also be causing reading problems in old drives. I
    know our ancient DVD player plugged into the TV has issues with proper factory-pressed disks when trying to play movies from new-fangled
    dual-layer DVDs ... often to the point were I have to watch them on my
    Mac instead.

    Either way, try using a newer external drive if possible.

    verbatim blues are very good.

    memorex can be anything. it's whatever was cheap that week.

    however, optical media is unreliable and very slow. use a usb stick
    instead.

    where 'old drives' are drives made before the early 1990s.

    anyone still using a 30 year old drive has bigger problems.

    reading dual layer is required as part of the spec. any drive that
    fails to read a dual layer a disc is defective, *especially* a disc
    that's commercially made.

    Could have a point there. I remember my old PowerBook G3 (also Matshita
    drive) had problems reading Memorex CDs and DVDs. Changing to Verbatim
    and/or Mr. Platinum CDs/DVDs gave no problems.

    My friend is still now and then using his old

    there was no 'vertical model from 1990' nor was there a cd-100, and i
    wasn't referring to cd-rom drives anyway.

    apple's external cd-rom drives had feet on the bottom and they sat

    the exception was the powercd, which apple was forced to release and

    Yeah, it wasn't used much. :(

    I've never bothered to look up official details, but from my own
    experience the normal CD drive in my old G3 PowerMac outlasted about
    three CD-writer drives that weren't used very often (even in just
    reading discs), so it sems likely there's some sort ageing issue with recordable drives themeselves which is worse than ordinary reader
    drives. Not really surprising considering the way they tend to rush out
    new tech these days.

    Hello.

    Do old PowerBook G4 (1 Ghz) have problems reading huge files like a 2.54 GB DMG that I burned to a DVD+RL? Finder says -- size and can't open it (damaged file). However, a 2012 13.3" MacBook Pro's mac OS Mojave v10.14.6 had no problems reading and opening it.

    none whatsoever, however, the optical drive could be failing and/or the disc itself deteriorating.

    Yeah, it looks like this PB G4's internal original Matshita DVD-R UJ-815 drive is going bad since it has problems reading. But then MacBook Pro's internal drive and my decade old 64-bit W7 HPE SP1 PC's internal Optiarc
    DVD RW AD-78220S drive had no problems.


    Can PB GB4's internal drive read
    burned (Memorex) DL DVD+Rs well?

    do you mean DualLayer by DL?
    According to Mactracker a PowerBook G4 (15 inch, FW800) supports
    DVD-R
    No Dual Layer, No +R

    Cheers

    Correct. I burned the discs in my decade old 64-bit W7 HPE SP1 PC and then use them
    in my PB G4's SuperDrive.

    defective or non-compliant, or the disc has deteriorated or was
    improperly burned, all failure modes, not the norm.

    +r and -r refers to how the disc is *burned*, not how it's read. very old drives might have occasional problems because writable discs are less reflective than pressed discs, but that hasn't been an issue in a very, very long time.

    ^^additional^proof^^

    again, stop reading things that you don't understand and try it
    yourself.

    I understand what I read.

    apparently not.

    i assume you mean dvd-r, and yes it can.

    I meant DVD-R, sorry, and that is what I'm writing

    what you're writing is wrong. very much wrong.

    what do you mean by "yes it can"?

    yes it can read +r and dual-layer.

    you're wrong.

    no i'm very definitely not wrong.

    all dvd drives can read dual layer. it's part of the dvd spec.

    please prove your claim.

    what part of "it's part of the dvd spec" is not clear?

    The DVD spec does not contain a single line how an optical drive has to
    be built.

    Yep. We have an old el cheapo brand DVD player plugged into our TV. It
    works fine with factory-made single layer DVD movie discs, but cannot
    play factory-made dual-layer movie discs (which do work fine via an
    external USB DVD drive plugged into my new-ish Mac).

    just about all movies are dual-layer discs, especially with all the
    extras and other stuff on them, without any indication of the number of
    layers.
