If I later determine that the problem us Xubuntu 14.04.3 then I have a spare. The new one has the same specs as the old one except that it will burn BD up to triple layer (100GB), where my old one was single layer (25GB). And my research indicates that most laptop optical drives are interchangeable, as long as they are the same height (12.7mm [mine] vs. 9mm). ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

After the above comment I used a can of compressed air on it, especially the two little glass-like bulby-looking things. Still can't read a DVD without massive errors. But, oddly, it reads CDs just fine, no errors at all, at least the two I tried, and it did so earlier today, before the compressed air therapy. ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Have you done any software updates recently? Maybe it is a kernel bug? You could try a live distribution with a different kernel. Live from a flash drive, not a dvd.

Are you sure it's not just dirty? I used to have a special "cleaning" CD that had a a little brush that would wipe the optics as it spun. I don't know if they still make those.

All media will mount, but any attempt to read them results in massive errors. There is more background to this. The laptop is a System76 Bonobo Extreme (17") that is now about two years old. At the time System76 refused to sell any laptops with Blu-ray drives because (as it was explained to me) they didn't want complaints from customers because Blu-ray movies wouldn't play in Linux. However, most System76 laptops are actually Clevo laptops, which System 76 buys from Sager, Clevo's only US distributor. So I ordered the laptop from System76 without any optical drive at all, and simultaneously ordered a Blu-ray r/w drive from Sager. I mounted the drive in the laptop and it has worked fine until now. So just now I called Sager to see if I could order a replacement drive, and they told me they no longer have any in stock because all their current laptops are sold without any optical drives at all. Google came up with a couple places to buy one, including one for $30 or so from Amazon, but the Amazon drive is a Panasonic BD-MLT UJ240AF, where mine is a Matshita (part of Panasoic) BD-MLT UJ260AF. Google has not been forthcoming with information as to whether the 240 is physically the same as the 260. If it would work I'd order the UJ240AF just because it's cheap enough. I wish I could figure how to pull the power to the drive from the command line, and then turn it back on. All I know is that 'umount /dev/sr0' is not the way to do it. ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

It just plugs in. Not to say there can't be a connection issue, but if there is it would probably require replacing the motherboard. First thing this morning I decided to reboot (which I hate doing). Afterward the drive worked perfectly, but only for one movie. When it was over I unmounted and ejected the disk, then inserted a different movie disk. Now it's back like it was before - constant error messages like the ones I quoted above. Next I unmounted the whole drive, /dev/sr0), with: sudo umount /dev/sr0 The command executed without error, but when I then inserted a DVD it was immediately recognized and mounted. My command did not do what I thought it might do. And the read errors continue as before. Since it worked perfectly after rebooting I am wondering if there might be a software issue rather than a physical failure. I was hoping that unmounting the whole drive would 'reset' it so it would work again, but that theory has failed, or at least my command was not the way to do it. Clearly, I can't keep rebooting just to change the media. Maybe my command above was not the way to do it. Is there anything else I can do so it completely goes away and then comes back? ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
