Q. Power and storage consumption

No I'm still stuck with ERROR: Unable to mount SD card : NOT_READY

Here's my wiring
Here the code;

var fs = require('fs');

// Wire up up MOSI, MISO, SCK and CS pins
function onInit(){
  SPI1.setup({mosi:B5, miso:B4, sck:B3});
  E.connectSDCard(SPI1, A8 /*CS*/);
}

var text = "Hello World!\r\n";

function saveToFile(){
  console.log('Append');
  fs.appendFileSync('testing.txt', "\tTest line\r\n");
}

//setInterval(saveToFile, 2000);

Here's how it executes;

I know the GPS is unplugged there by the way. I had it logging the GPS. I had it writing a like to a file. Now together I can't write to the SD and this first SD test isn't running.

I reflashed the pico too. same thing.
