Are the cards all the same size and speed? If not is there a pattern to the failure, ie, fast ones fail slow OK etc. Have you access to another card reader? Are there some cards that work every time? Can you read the failing cards by using the camera plugged into the computer?
Don't worry about the SMART message, I don't believe it is relevant to external memory devices.

The cards range in size from 1GB to 8GB. But there is no rhym or reason to which ones are readable and which ones are not. One of my 8GB and 4 GB works while anothers do not. All the same brand. The card reader is fairly new and a top of the line reader. I do not think the reader is the problem since it works for some of the cards. Disc utility shows the card when it is not readable by the computer. So the reader seems to be fine. A card that was not readable by this computer I was able to read it on my old macbook pro just to save the files.

Is the Card reader USB 3 and plugged directly into the computer? I understand that there have been some compatibilty problems with USB 3 peripherals, a search of these forums would probably find some I. A simple test is to put a USB 2 hub between the computer and the card reader, this will force both items to USB 2, if this works it would point to that type of incompatibility.
If it is none of these and you have tried other ports on the computer I would try another type of reader.
