No problem! What you might want to do is buy an internal burner but also buy an external enclosure for it. Some external burners, like ASUS's current model, are junk, too. I don't buy DVD burners anymore, but if I were going to get an external drive, I'd get an internal SATA Pioneer BD 209M burner and put it in an enclosure. They're pretty much my go to drives, although I have an LG internal BD burner as well because with the latest firmware, P209M drives don't properly write to Ritek 8x DVD+RW anymore. And it's been 2 years since they last updated the firmware, so it's not like they're ever going to fix that.
The LG, unfortunately, has more problems. It doesn't properly write image files to BD-R/RE DL in ImgBurn, although other apps will write image files to it. It's a weird "issue" that has no logical reason for being, but repeated experiments by me and the results of another user prove it's there. Even though there's no difference in the code for writing an image file versus the on fly writing that does work. LG's are also pretty bad readers, so that might also explain your problem. Since it's failing on Verify, it's failing on a read operation and my LG fails to read a lot of discs my Pioneer would. Although I did have a weird case where my Pioneer wouldn't read a disc my LG would. Go figure! BD-RE DL's formatted as giant floppies also won't write to the 2nd layer. You'll get a weird bogus Windows message saying the source file couldn't be "read" even though it's a write operation that's failing! Lastly, LG's are capped at writing BD-RE SL formatted as a giant floppy at 1x, even though the drive writes BD-RE SL at 2x and the Pioneer writes the formatted discs at 2x.
Personally, I'd avoid LG's all together if I could. The only reason I still use them is for the writing to 8x DVD+RW and that it reads and writes Ritek 6x DVD-RW that my Pioneer and ASUS USB won't. I got the last USB model made before ASUS's current one, back when I thought ASUS was a quality manufacturer. But, their current USB contains the same model drive, internally, as their current internal BD drive. And that was junk. 2 different copies of the same model did the same thing: destroyed 8x DVD+RW and BD-RE SL and DL! After writing to them, even when they were brand new and had never been written to before, they were totally unreadable after burn and could not be salvaged by reformatting. Any drive is stuck in a forever reading loop trying to read them, so you CAN'T format them to try and salvage them! The first LG I ever had was a DVD writer rebranded for IOMega. I got rid of that pretty quickly because it wasn't writing to DVD-R correctly. It was writing discs that caused skips in playback on DVD Video discs that my Optiarc drive didn't do. There's an old joke that says LG stands for "Lucky Good" because it's lucky good IF you get one that works right.
That's why I stick with Pioneers. They have their own issues, but they're mostly annoyances, like the aforementioned firmware issue. Plus, I had 2 drives display the same quality control fault. After about 7 months, the eject button wouldn't work 1 out of 10 times. Pressing the eject button or issuing a manual eject command in ImgBurn wouldn't work, but, a 2nd immediate press or eject command in ImgBurn would work. And, it seems that every eject command ImgBurn issues after a write/before a Verify would always work. But, Pioneers generally last a long time, too. My first Pioneer is still in good working order after 4 years. I keep it on hand for use when I need one while replacing another. The 2nd one I only just had to replace earlier in the month because it wasn't writing files to discs anymore, but, I'd been using it for 2 years. The 3rd one I had wasn't as good, though, requiring replacing after 7 months. The 4th one I had went back to Amazon.com because it was borked right out of the box. Wouldn't write to Verbatim quality BD-R that my first Pioneer 209M was still writing to.
