The latest is interesting but not revealing - I burned and verified a disc in the alternate USB port and expectedly, it burned and verified fine. I then switched the cable from that port to the one producing semaphore errors and burned and verified another disc. This port has consistently been having the semaphore issues, but this time, no problems at all??? Go figure. I'll try the problem port first next time and see what happens. The problem may have been cleared by using the alternate port in this case. In any event, this issue is mostly an inconvenience but certainly curious.

You must have read my mind. Here's a post I tried submitting this morning, but the site wouldn't let it post so I was going to try another computer but you beat me to it: Since it's only affecting the verify, I'll try the original port next time I burn and see if the problem returns, and then try again using the alternate port that worked. I've been using the "bad" port for almost everything USB up to now, with no problems of any kind. Chalk it up to "weird digital things". As long as I know the LG has to be used with the alternate port (and it works there), I'm happy. The only thing that would make me happier is if I could use Verbatim discs with my internal drive like I used to, and not need the LG every time I want to burn a BD.

I tried my next burn using a different USB port on my laptop and, as dbminter mentioned, that fixed the problem. I never thought about doing that since I didn't have a clue as to what would be causing a semaphore error. I gave that a try and thought if it didn't work, I would try the old media, but just changing the port worked fine. I assume it has something to do with the data rate capability at that port?? Thanks for the hint.

No problems writing (except with my internal drive). I meant that I had no problems with the old discs using my internal drive - I haven't tried any on the external drive (LG BE14)so don't know about that. This has been happening ever since I started using the external drive (and the new discs) - it didn't suddenly occur other than when I switched disc batches and couldn't use my internal drive. Is it possible that the new discs can't be read by the LG unit and errors in reading a written disc cause the studder with the error message? They do play fine in my stand-along BD player though so........ I'll try to use some different discs in the external and get more data but anyone with ideas is welcome to chime in. Thanks ISF God

I've been using Verbatim 50GB discs with great success (no bad ones) until I purchased my last pack. My internal burner started having real problems and couldn't make it through a single one without popping up an error (the older discs still worked fine). I had previously purchased an LG external burner and decided to try it. It will burn the new discs, but in the verify process it keeps showing the error - "Failed to read sectors --- Reason: The semaphor timeout period has expired", after which it produces the message - "Waiting for device to become ready"...... and then it recovers and starts verifying again. Most all verifies have completed but seem to take longer due to this behavior. I haven't tried the burner with any other discs (I don't have any) and the discs play fine so burning is successful (which the verify does indicate when it finishes). The external burner is connected via my laptop USB 3.0 connector. Is there a setting in ImgBurn that could be causing this? What else might be responsible? Thanks.

Thanks dbminter & LIGHTNING UKI. That's what I thought was the case. Unfortunately, Panasonic didn't issue any firmware upgrades before they discontinued the deck (Pioneer is now offering one that looks identical)so firmware mod is not an option. I guess I'll burn through these discs at X2. I managed to find more of the original type on-line so will see what I get when I order. It's a bummer that these disc companies change their source and everything goes south. Had that happen with TDK but in that case, couldn't burn at all. Again, in that case, TDKs response was "buy a new drive". What's wrong with this picture?? Anyway, thanks again.

I've been using X4 MEI-T02-001 (Verbatim) media to burn ISOs quite successfully (Panasonic UJ265 deck) and I think the burns even went beyond the 4X speed when AWS was selected for speed. No bad burns in over 100 runs. Recently I got new "Verbatim" media (supposed to be the same type according to the ad), but it was X6 VERBAT-IMf-000. All the burns failed when AWS was selected for speed. I tried using X2 (ok) and X5 but the X5 noted that only X2 and X6 were possible for the new media and defaulted to X2 which burned ok. I can't provide a log since I already trashed it (sorry), and I don't want to make another coaster unless I have to so I guess I'm asking if anyone has suggestions for getting the speed back up on this new media (anything in ImgBurn I might be missing)? If need be, I can go back and waste another disc and get some log info to post. Thanks.
