Don't Format SD cards with OS utilities!

Hello everyone,

I am trying to use an SD card with my UNO for the first time and I'm running into a lot of the same problems that other posters have experienced. Unfortunately, I have not had any success with the posted solutions.

Here are some of the specs for my setup:
Board: Kuman UNO
SD Breakout: velleman VMA304
Arduino IDE: 1.8.5
SD Library version 1.1.1
SdFat version 1.0.16

I first tried running the built-in ReadWrite tutorial, but the SD card initialization failed. I then formatted the SD card with the SD Card Formatter version 5.0.1, from the SD Association's website, but still the initialization failed.

After that, I downloaded the SdFat library and tried running the SdInfo example. It was able to pull some of the info from the card, but still failed to initialize. The last thing I tried was formatting the card again using the SdFormatter in the SdFat library, but the serial monitor displayed the following error after starting the formatter:

.........
Enter option: F
Card Size: 15552 MB,

Erasing
.error: erase failed
SD error: 5,4f
.........

Is there anyone who has seen or had experience with this error before, or who could possibly point me in the right direction to solve this issue?

Thank you,
