Here, this is what it should be

#include "robot-config.h"

// storage for some information to save
uint8_t     myTestData[ 100 ];
uint8_t     myReadBuffer[ 1000 ];

int main() {
    // set the test data to something detectable
    for(int i=0;i<100;i++) {
        myTestData[i] = i * 2;
    }
    
    // write test data to SD Card
    int nWritten = Brain.SDcard.savefile( "test.h", myTestData, sizeof(myTestData) );

    // did that work ?
    if( nWritten > 0) {
        // display on screen how many bytes we wrote
        Brain.Screen.setCursor( 2, 2 );
        Brain.Screen.print( "We wrote %d bytes to the SD Card", nWritten );

        // now read it back into a different buffer
        int nRead = Brain.SDcard.loadfile( "test.h", myReadBuffer, sizeof(myReadBuffer) );

        // display on screen how many bytes we read
        Brain.Screen.setCursor( 3, 2 );
        Brain.Screen.print( "We read %d bytes from the SD Card", nRead );

        // and display some of the data
        Brain.Screen.setCursor( 6, 2 );
        for(int i=0;i<8;i++)
            Brain.Screen.print("%02X ", myReadBuffer[i]);
    }
    else {
        Brain.Screen.printAt( 10, 40, "Error writing to the SD Card" );        
    }
}

somehow text for arrays was messed up. So code like this myReadBuffer* should be myReadBuffer[ i ]
I suspect that a migration script mistakenly took [ i ] as an italic tag or something like that.
