I/O Error with New Drive

[midnitedave]

Hello all! Long time user, first time poster.

I've been through the ringer with this and have combed over old form posts and FAQs to no avail, so I'm hoping y'all can help me resolve this.

What I'm using:
Verbatim BD-R DL 50gb 8x
OWC Mercury Pro 16X Blu-ray Drive

 

What I'm trying to burn:
3x Project4K ISOs

The story:
Originally, I used my old drive (Samsung External Blu-ray Writer TSST SE-506CB/RSBD 6X USB 2.0 Slim) and everything went well for the first two ISOs ("SW" & "EM"). However, when I tried burning the third ISO ("JD"), I received a L-EC Uncorrectable Error message. After some research, I determined it was the drive. This theory was further proven when I tried to burn the first two ISOs ("SW" & "EM") again, only to receive I/O Errors. 

So, I replaced the drive (OWC Mercury Pro 16X Blu-ray Drive) and tried burning the "JD" ISO again with success (both with the burn and verification). However, just to be sure, I attempted another burn with the "SW" and "EM" ISOs and still receive an I/O Error (log below for both). 

It's worth noting that I've tried burning these at all supported speeds listed by Imgburn (2x, 4x, 6x) as well as with AWS with the same result. I'm not sure what else to do and would appreciate all suggestions.

Thank you all for your time and be well.

The actual drive in the OWC setup is an LG.  I'm not familiar with that particular brand, but I do know the WH16NS40 did not properly write to BD-R DL and BD-RE DL.  9 times out of ten, they would fail verifies.  Now, that was some years ago, so a firmware update to LG drives like the NS40 might have fixed it.  The issue wasn't present in the NS60, but LG discontinued that model.

 

You could try seeing if there's a firmware update for your drive.  In Write mode, right click on the drive from the drop down menu and select the last option in the context menu, the one to check for a firmware update.  Install the latest one if there are any and try again.

 

If that doesn't work, the only thing to try is a different drive.  Preferably not an LG model.  I use ASUS's BD internal drive in a VanTech USB 3.0 enclosure, but I've not tested any DL BD discs in it.  If you're going to use your own external enclosure with a BD drive, you will need a USB 3.x enclosure; 2.x won't do.

 

ASUS makes an external BD drive, but I've yet to test it.  I intend on getting one probably in December, but I don't have any BD-R DL to test it with.  I've never even burned a BD-R DL before, only BD-RE DL.

@dbminter Thanks for your response!

Checking the firmware was the first thing I did and I can confirm it's the most recent version. I saved all the packaging just in case, so I'll be returning the drive today.

Is this the ASUS Drive you're referring to? If so, I'll pick it up once my return has processed.

You mention having never burned an BD-R DL before. Is this moreso due to preference, or is there an advantage I'm not unaware of (besides it being rewritable, of course)?

Yeah, that's the ASUS I have bookmarked to try out in November.  Someone else on this board had tried it out and it seemed to do the trick for solving their issue.

 

I just never have had any BD-R DL before.  Just BD-RE DL.  I needed rewritables for monthly system backups so I could reuse the discs and my backups were all larger than a BD-RE SL.  I've since moved to USB SSD's because they're much larger and read and write much faster.  I also as a matter of "trust" that I only use DL media when I have to.  Like for those backups I mentioned or DVD+R DL for DL DVD Video discs.  When you go beyond one layer, you double the chances of having a read issue, right at the layer change(s) most often than not, as seemed to be happening in your case.  So, I could have saved space with BD-R DL discs for backups which also would have read and written faster than the rewritable DL's, but I didn't want to run the risk of, years later down the road, a backup being unreadable.  So, I stuck with single layer BD-R.

 

To put it into perspective, in the 10 years or so I've been burning BD-R's for backups, I only just a few weeks ago encountered my first that wouldn't read.  And that was something I "knew" years ago when I wrote it.  The drive was dying and there was a recovered read error during Verify on burn.  I performed a manual Verify on that same disc and it passed that time.  However, that drive that burned it was replaced shortly after that due to various Verify failures on future burns.  I should have burned the data again in the replacement drive while I had live copies, but I didn't.  Thankfully, it was temporary files that I managed to recover from other sources a few weeks ago, so I didn't lose anything.

That's a great track record! Hopefully I can get to that point with a new drive.

For me, it's primarily movie backups which strikes single layered discs as an option since there isn't enough space.

I'll keep you posted on the situation once I've tested everything. Thanks again for the help!

Be aware that I've just begun testing one of these external ASUS drives and right out of the bat, I notice it's a slower reader.  Took 5 minutes to read 300 MB off of a pressed data CD.

Another reason not to get that drive: it writes at only 4x to 8x DVD+R DL discs.

 

If you're going to go with the ASUS, get the internal model and put it in a VanTec or Other World Computer USB 3.0 enclosure.

Hello again!

Thanks for posting an update regarding your tests. My return just finished processing, so I haven't even gotten a chance to look at other drives. I'll certainly pass on the external ASUS. That said, are there any internal drives that come highly recommended (and can be placed into an enclosure)?

ASUS's current internal BD model, BW-16D1HT, is the one I use in a VanTech 3.0 Gen 1 enclosure.  The WH16NS40 from LG is another possibility although last time I used one over 5 years ago, it failed to write BD DL media 9 times out of 10, backed up by other users who experienced the same thing on this board.

 

Pioneer's current 213 model is ALMOST there.  It's a year and a half old and needs to conquer a few firmware slow writes.  For instance, it, too, only writes 4x to 8x DVD+R DL.

 

I put in for a return on the external ASUS BD drive.
