Anyone else experienced this:
I have a nice modern LG WH16NS40 Blu-ray rewriter, and a nice modern
computer case with zero drive bays, so I got an OWC external drive
case with sata -> usb3 to hold the drive.
Everything I've tried works like a champ on this drive except
trying to rip a DVD. It hangs at open as long as I care to wait.
(Blu-ray, no problem, cdrom, no problem, writing Blu-ray, no problem).
The strace looks like:
stat("/dev/sr0", {st_mode=S_IFBLK|0660, st_rdev=makedev(0xb, 0), ...}) = 0
openat(AT_FDCWD, "/dev/sr0", O_RDONLY <-- never finishes till I unplug it
External USB cases often work well for simple use cases, but each model has
issues
with off-label use cases. I had 2 of the same model from the same
vendor
have different issues.
OWC has been better than the average low-priced Amazon kit. Have you
contacted them?
If I put the drive in another computer that does have an internal drive
bay, it reads DVDs just fine with a direct sata connection.
Meanwhile an old small portable USB powered pioneer drive can read
DVDs just fine.
Just curious if there is some kind of known bug out there. I guess
my work-around is to always use the pioneer for DVDs.
The bug may only appear for certain combinations of drive and USB
chipset. Check for firmware updates for the drive.
