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. :)

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.

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.

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.

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

years back that some of the Matshita and Sony*) SuperDrives didnot like
the DVD+R, but worked fine with DVD-R - both single and dual-layer DVDs.

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

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.

all dvd drives can read dual layer. it's part of the dvd spec.
almost all movies are dual-layer discs. if it can play movies (which it
can), then it reads dual layer.
+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.

that doesn't say what you think it does.
it lists the various *writing* modes, which is certainly important, but
not relevant for reading.

stop reading things you don't understand and try it yourself.
there is no issue with reading dl discs, unless the dvd drive is
defective or non-compliant, or the disc has deteriorated or was
improperly burned, all failure modes, not the norm.

millions of others have watched dvd movies with various apple optical
drives without issues.
