Card reader automatically eject media during file transfer

I have been having this frustrating issue with several compact flash cards and card readers. First I thought the card reader was malfunction and I get another to try, same issue. So that I thought is the CF card, but several other CFs having same issue as well. Only one particular brand is fine, Sandisk.

I have done search on Google and apparently a few out there is having same issue as mine, but there's no solutions. What could possibly be the solution for this?

MacBook Pro, Mac OS X (10.6.7)

I seem to have solved this issue for me by using Terminal instead of Finder to copy. Here's the sequence of steps:

1. Open terminal.

2. Go to desktop by typing:

$ cd /Users/yourusername/Desktop

3. Create a destination folder by typing:

$ mkdir DestinationFolder

4. Go to the folder containing files you want to copy, in my case:

$ cd /Volumes/EOS_DIGITAL/DCIM/100EOS5D

5. Use this command to copy all files from 100EOS5D to DestinationFolder

$ cp -av * /Users/yourusername/Desktop/DestinationFolder

where -av instructs the copy all files (this what * means) from current directory to DestinationFolder, and options "-av" mean "archiving" and "verbose", that is copying all files as is and displaying progress in terminal window.

I've been having this problem since, if my memory's correct, upgrading to Snow Leopard. This solution worked on new MacBook Pro 13'' Retina (late 2013) with Mavericks 10.9.1.

The issue is still occurring, apparently. I purchased a Digitech multi card reader and it keeps ejecting all cards, sometimes whilst I'm importing photos. I'm running the latest version of sierra.
