OK folks, again...what model is the PIC and what is the CCS version?

I seriously doubt if the 16F877, has enough RAM. You will definitely need the option:
#device *=16
in your enfin.h file, as the line immediately after including the processor defines, to have 'any hope'...

First off you try to read comments in FAT.c library and you will immediately see that first you have to use fat_init function before using of any other functions. Second the issue can really be in small RAM memory of your MCU. You should read datasheet and then you will know if that's not problem.
Last thing in your code on this forum don't use this if(fatopen(filename,mode , &stream) != GOODEC) in condition because you don't know if the compiler doesn't throw return value first and then it compares condition with incorrect value. You rather use this
int8 check;
if((check =fatopen(filename,mode , &stream)) != GOODEC)

also...
unless you use PROPER signal translation hardware you'll never get a 5 volt PIC to 3 volt memory card.Can't be done..
So before you go any further, show us the schematic of what you have..or the pinout connections.
No sense blaming software if you have wrong hardware !!
