Note 4 detect SD card but can't read it!

I have a very specific problem that I have been trying to solve.

I have a Galaxy Note 4.

For the past few days, my phone has not been able to read the SD card and is stuck on "Preparing SD Card"

Here are the facts I have come up with:

- My phone will not read any SD card and will continuously stay at "Preparing SD card" no matter how long any card is in the phone
- The current SD card can be read in others phones and my computer.

This leads me to believe the SD card is not corrupted and that the files may still be able to be accessed. The other info I have found from forums tells me the best way to get the phone to read an SD card again is to reset it, but I don't want to do that.

Try to use app name [ SD insight ] from the market, it can read the manufacturing of SD and all the information! But still cant browsing the file.

I would be so appreciative of any suggestions.

Thank you for any help you can provide!
