Lightroom Mobile import process results in corrupt RAW files

I posted this elsewhere and it was suggested that I post it here for others to see and provide feedback.

Over the course of 5 months I've been attempting to address some random corrupt RAW files after they have been imported into LR Mobile via my Ipad Pro. 

Here's what's been done to try to rule out hardware and/or user error...

1.  I Copied the LR catalog and images to a new system so that these guys reside on an internal drive.  I've ruled out any problem with Win7 DASD having corruption on the drive.  This was done via the Backup/Export process.  The new LR system came up without any hitch.

2.  Win7 is also a clean install.  So system was started up from scratch.

3. LR on my Win7 system is always closed until after I've finished my import of images on my IPAD Pro via the Lightning card reader.

- In anycase, as of this past weekend, I didn't even bother to startup LR on my Win 7 system.  So, the Win7 component can be ruled out..

RECREATE: I import images into the LR Camera roll via a Lighting SD CardReader reader (I've also tested with my EyeFi cards via Wifi) on my IPAD Pro.  Once the import is done, I start LR Mobile and it imports the images.   In the last 4 imports, I've seen immediately that a few of the RAW images show up as corrupt on the IPAD immediately.

So everyone has been pointing at my Card Reader.  Well, this problem was easily recreatable when I was using my EYEFI cards to import the images into the EyeFi Software/Camera Roll, and then LR Mobile.  I bought the Apple Lighting CardReader with new SD cards to test the process.  It can be recreated randomly with either import process.

Important note: If I take the images from the DCIM directories on the Ipad and compare them to the LR files, the corrupt ones are clearly a different size.  Slightly different, but different.

If I copy the corrupt images from the DCIM directory and copy to the LR location of the RAW images, the files will show up correctly in LR Mobile and Desktop.

Seems to me that I'm back to thinking there's an issue with the import process or bad storage space on the IPAD.  Doesn't make sense since the original files are ALL GOOD images. 
How do I debug this further?

Rodney

What I'm hoping for is some direction as to how I can narrow down the focus of where the process might be broken.  Any assistance would be appreciated.  I know that many threads are available regarding the Import process, but I've attempted to rule out the usual hardware suspsects and my only option is swapping out the Ipad.

Have you tried taking the SD card that produces corrupted raw files when imported to the iPad and  import them directly to your LR desktop? Use a USB card reader and see if any files show  as corrupted. If so then you have your answer.
