SD card not mounting or unmounting automaticly (no replies)

I can’t get the sd card to work. Whenever I put in or take out a card marlin does not seam to mount it or unmount. If I use Repeater host to manual mount an unmount, the card works fine. Or I can insert card and reboot and it will see the card, if removed the card, marlin thinks its still there I had some pixilation issue and added this code to the configuration.h file :

#define ST7920_DELAY_1 DELAY_NS(0)
#define ST7920_DELAY_2 DELAY_NS(0)
#define ST7920_DELAY_3 DELAY_NS(125)

Don’t see how this effecting the code but it may be issue.
I am running marlin 1.1.19 on a MSK gen1.4 with Reprap Discount Full Graphics Smart Controller. If anyone has some insight on this I would greatly appreciate it.

Thanks.
