Any Way I Can Handle Problem Where My USB Hard Drive "Unmounts" Itself Causing Imgburn to Abort

[audioresearch]

I'm using Imgburn to copy files from USB hard drives to BD-R Bluray discs.

Sometimes the USB hard drives are having problems where they stop being "ready" and unmount themselves so that they no longer even appear in Windows Explorer while I'm copying files from them to Bluray disc using Imgburn.

Imgburn halts and displays an error message saying something to the effect that the hard drive is not ready. It is not saying the Bluray destination drive is not ready, just the hard drive being used as the source is not ready.

I tried unplugging the USB hard drive cable and then plugging it back in and the drive once again appeared in Windows Explorer. I even copied the file from the hard drive that was being copied when Imgburn aborted to another hard drive as a test that the hard drive was really once again ready and working and that copy completed with no errors so I know that source file was now once again readable.

What I then wanted to do was get Imgburn to resume where it left off and continue copying files from the now-ready-again source hard drive, but Imgburn would not do that even when I clicked on the "try again" button (it just kept saying hard drive not ready even though it was clearly now ready again) and I could not find a way to get Imgburn to resume from where it left off. Instead I had to throw out the BD-R disc I was using and start all over again.

Is there a way to get Imgburn to resume where it left off once I get a disappeared hard drive to re-appear again?

I haven't included any log files here because I really don't think they will add anything I haven't already pointed out that is relevant, but if you ask, I will add the log file.

Your best bet is to see if this is a repeatable problem outside of ImgBurn.  You said you copied the FILE that was failing, but it may be a use case only triggered if the entire dataset is being copied.  Try copying ALL of the data set you're adding in ImgBurn to another hard drive from this USB and see if it fails then in File Explorer.

 

If it doesn't fail, then it's ImgBurn's problem.  Unfortunately, there's not much you can do in that case.  Just copy the files from the USB HDD to another HDD alternate location and attempt to use that "cached" copy as the input into ImgBurn.

 

While you can't get ImgBurn to resume where it left off, I think I can see what is going on here and how maybe to better proceed going forward.  It sounds like you're adding the files from the USB HDD to BD-R directly with the Write Files option in ImgBurn.  Instead, create an ISO file first with Build mode then burn that ISO to a BD-R.  This way, if the copying fails, you won't lose a BD-R to a USB HDD that has lost connection.  If it fails in Build Mode, you've just wasted time.

Post the log please so I can see the error message when it first occurs and then once you've reattached the drive and hit retry.

Here is the log file. Note that I made numerous repeated attempts to resume the writing to the BD-R bluray disc after I had unplugged and then plugged back in the USB source hard drive. Even though that USB hard drive was clearly connected again and working fine, since I was able to successfully copy one of its files to another device as a test that the USB hard drive was working again, I continued to see only error message that the device was not ready even though it now was ready. The USB source hard drive is device H:. The output device was the Pioneer BD-RW BDR-209 Bluray drive. The first "device not ready" happened when the USB drive disconnected itself but all the "device not ready" messages after the first one happened after I unplugged the USB source hard drive then plugged it back in again and it was then once again working fine and I hit the "try again" button (or whatever similar name it was called if not that) many, many times trying but failing to get ImgBurn to resume where it left off and finish writing to the Bluray output disc.

I would try the Build mode as a test of the USB HDD, too.  Instead of writing files and folders directly to the BD-R, trying building an ISO file of the same contents first in Build mode.  See if the USB HDD disconnects during the Build ISO creation, too.
