Windows 7: weirdly slow blu ray read

weirdly slow blu ray read

Just got a nice new blu ray burner/reader and took it for a test drive. Burned a 23GB set of files very nicely, took less than 13 minutes and then I popped the disk back in to read it.

After "calculating" for 20 minutes, Windows explorer started the read and said it had 22 hours left to go. I let it run for about 1/2 hours and had read in just over 1,000 files and still said it had 22 hours to go and from the rate at which it was transferring files to the HD I could see that it wasn't kidding.

Any clue why a Windows 7 system would do this? Could I have some configuration setting wrong?

Device is:

LG WH16NS40 16X Super Multi M-Disc Blu-ray BDXL CD DVD Internal Burner Writer Drive

Here's what the progress windows looked like when I gave up.

New clue. I ZIPPED up the 87,000 files into a single ZIP file and wrote that and read it back. Write was about the same 12 minutes as doing all the files but the read went down from 22 hours to about 9 minutes. Clearly the problem has something to do with reading LOTS of files but that doesn't really tell me anything. Does it suggest anything to anyone else?

Just tagging along as I have the same make and model drive and it will not read anything at all. Not data or commercial disks.

(Unfortunately it's too late to return the thing )

Well, that's a bummer. How did you not discover that before it was too late to return it?

I have a bad habit of buying stuff when it's on a good sale (such as Cyber Monday and the like) and long before I actually need it. Kind of like now where I've been buying the parts for a new build for well over a month. I might not even get to building it for a week or two. Being a working adult it's tough finding time some times...

No, didn't even think of it... So I updated the firmware and sadly, no change: the unit still won't even read a disk. Thanks for the tip though!!

What's it sound like when you put a disk in?

Nothing noticeable. It's as quite as my Samsung DVD burner. I'll put a disc in the Samsung, the light blinks, and I don't hear it. Once the light stop blinking, then I can hear it a little.

I'll put the same disk in the LG and the light starts blinking as normal. I've let it blink for an actual 3+ minutes and it just keeps blinking. After a longer while (never timed to this point; maybe 5 or 6 minutes) the light stops blinking. No Autoplay notification appears. If I click on the drive in Windows Explorer, I get the message to insert a disk and the drive bay will pop open.
