Lightroom/Camera Raw & DNG: DNG conversion is reconverting even though only raw is checked.

Doesn't finish the files, doesn't delete original, just hangs. I've attempted to run these three or times and it's time to give up. This is broken. Tiresome. I don't know how many open conversations I have here but I'm looking at LR behind and it's sitting at 484 photos where it's been sitting all day. I don't think Adobe got this big like this.

It's not clear if you are converting to DNG upon Import, during export or using the menu "library -> convert photo to DNG" however the answer probably doesn't matter? 

First though are the files some other type of RAW file (CR2, NEF, AWR, PSD, TIFF, Etc.) or Jpg?  If the files are Jpg, then there is usually little or no value in converting them to DNG as the data loss has already occurred and converting them to DNG can't get that back but does create a much larger file size anyway.  

Most cases such as what you describe stem from LR running low on memory (RAM).  They have not been very good at either telling you they are low on memory or very good at throttling back what they are doing to consume less memory.  If this is the case, you may want to "quit" or "Shutdown" other applications running on your computer while LR is converting which in a few cases fixes such problems.  However, the best approach is to hand it smaller chunks of files to convert at one time.  Maybe just a few folders at a time.  If that works, I also find it useful to Close LR and Re-open it again between chunks.  I know this shouldn't matter, but at least on Windows (I don't know about Mac's) it seems to help.  I suspect that LR is remiss in releasing memory in certain cases when it is done with a task and it forgets it still has the memory reserved and then tries to get more.  Anyway, see if that gets you through.

Thanks Dan, it starts out as converting on import, AWR files, then proceeds to make a mess, converting some, not converting others, converting some twice so I wind up with ding-2 duplicate files  then just quitting in the middle. It's less than 1,000 but it's on an external drive which I believe is the problem in a nutshell. That simply does not work. At this point I'm resigned to this software being a kludge on many things. I manually converted them.

I'm not really an expert on that technical level, but flaky drives and produce flaky behavior with little more evidence than slow operation in addition to the flaky behavior.  Processes then to hang (or freeze) - sometimes till you reboot but sometimes it springs back to life after many minutes of being frozen (during which time it is trying, waiting, timeing out, trying, waiting, timing out, etc. 

You may want to run ChkDsk (or similar utility) on the external drive to check it's health.  You may also want to see if LR exhibits the same behaviour if you use your internal hard drive instead of the external.  In other words on import use a folder on the internal drive instead of the external drive (you can alsway move the folder later)
