Blu-ray drive recognized, but discs are not (ie won't mount)
Posted: Wed Jul 27, 2011 10:04 pm
I am having more failures than successes mounting BD discs. The drive makes several spin attempts, but never spins up to speed, then gives up, with the disc never mounted.
This doesnt appear to be a MakeMKV problem, because the discs do not mount in the Mac Finder either, but I thought someone here might have some ideas.
CONFIGURATION
MacBook Pro (13", mid-2010), 2.4ghz Core2 Duo, 8gb memory, running Mac OS 10.6.8 (just updated from 10.6.4 in hope of fixing this)
Plextor PX-B120U external USB BD-ROM drive, running latest firmware, v 1.10 (released 7/19/2011)
MakeMKV 1.6.12, with this release's DASPI 1.3 package installed
NOT PROBLEMS
The drive itself does appear (apparently normal & fine) in Apple's System Profiler and MakeMKV.
The drive _and the discs_ DO mount when attached to a Dell tower running Windows Vista Business.
DVD discs in this drive DO mount fine.
I have had good success in the past using this exact drive unit, with previous versions of MakeMKV, mostly on a MacBook (13", 2009), 2.0ghz Core2 Duo, 4gb memory, running Mac OS 10.5.8, although that system doesn't mount them now either.
MY CONCLUSIONS
I don't think it's the drive, which
- though portable, is not carried around, is treated gingerly, and is in like new physical condition.
- is recognized by the OS and MakeMKV
- was succussfully updated to the latest firmware
- does mount discs under Windows, both before and after the firmware upgrade
I don't think it's the discs, because it occurs across several of them.
As I mentioned, I don't think this has anything to do with MakeMKV, unless it's the DASPI. I've read here that DASPI (1.3) is involved only in scanning, and not mounting.
I don't know what it might be, but I'm thinking there's some kind of lack of support in the Mac OS for this drive (which is reported by users as Mac-compatible, but not sold by Plextor as such), or for BD discs in general.
Any ideas, either specific or directional?
