Ok so I changed the "quote" to "code", and now my code should be easier to read 
I'm currently working on a near space balloon engineering project for school, and right now when I try to log data to a micro SD card from multiple sensors, whenever it finishes logging and I check the micro SD card the data becomes all garbled up 
Here's the code:
#include <SD.h>
#include <Wire.h>
#include <ADXL345.h>
#include <Adafruit_BMP085.h>
File dataFile;
int gyroPin = 0;
int gyroZero = 495;
int tiltXPin = 1;
int tiltYPin = 2;
unsigned long millisecond;
Adafruit_BMP085 bmp;

And here's the data output (note how it was only supposed to log 10 times whereas in the output it was logged 20 times with incorrect data in between):

Please help... I really don't know what to do! :~
Thanks for the help!
