Hi
I am using the latest generation datalogger shield with a Genuino 101. The CardInfo sketch successfully ran when I first set it up but now is telling me the card isn't recognised. In the time since I first ran it and now it has been knocked around a bit because of the nature of the project, which could be causing the issue, but I don't know what to check. I have additionally needed to resolder some connections on the prototyping area, at the analog pins 2-5 and at GND and 5V, but I haven't touched digital pin 10 or any of the other header pins. When I check if there is a connection between the male header pin at 10 and the CS pad with a multimeter, it registers a connection on both sides of the pad. I believe the SD card is formatted correctly because when I insert it into my laptop I can see that it is formatted with FAT32 in Disk Utility. I've attached a photo of the board, but the quality is a bit iffy, I can try take a better one if necessary. What are the next steps I should take to troubleshoot my board?

Re: SD card not recognised - datalogger shield
First thing I'd do is to try another card. We've seen lots of problems with bogus cards.

Thanks for the reply, but I tried that and it still doesn't work

Re: SD card not recognised - datalogger shield
Do you have the MOSI, MISO, and SCK jumpers soldered on the back? Are those solders good?
There really isn't much of anything that can go wrong here, apart from the soldering, the only thing between the 101 and the card is a buffer chip used for level shifting. Those really don't go bad. That's why we tend to suspect the card itself.
Can you see if any of the pins inside the card slot are bent or broken?

Re: SD card not recognised - datalogger shield
Thank you for your responses, it turns out the Genuino was the issue rather than the shield. I replaced it and it now works.

Re: SD card not recognised - datalogger shield
great!
Question: Did you replace it with another 101 and it worked? Or is it something to do with the 101 design?

Re: SD card not recognised - datalogger shield
I replaced it with another 101, so the design can't be at fault, it must just be that my original was broken in some way. I haven't troubleshooted (troubleshot?) it yet so I can't say what exactly the problem was.

Interesting, I just ran into the same problem and switching out the Genuino fixed it. Glad I had a spare

Re: SD card not recognised - datalogger shield
I bought the Adafruit ultimate gps logger shield and have the gps portion of the shield working. I would like to log some data and the logger does not appear to work. I am using a 2gb drive. Using the CardInfo.ino program and changing the chipSelect to 10 reports the following data:
Initializing SD card...Wiring is correct and a card is present.
Card type: SD2
Volume type is FAT16
Volume size (bytes): 1971159040
Volume size (Kbytes): 1924960
Volume size (Mbytes): 1879
Files found on the card (name, date and size in bytes):
Everything looks good, except there are two text files on this drive which this program is failing to recognize. One a zero-size file and another a 1k size file. When I run the createDeleteFile.ino with chipSelect set to 10, I get the following data:
Initializing SD card...initialization done.
example.txt doesn't exist.
Creating example.txt...
example.txt doesn't exist.
Removing example.txt...
example.txt doesn't exist.
I have tried removing the forward slash and preforming a conductivity check of the pins 9, 10, 11, 12, 13, 14. I have tried the SparkFun RedBoard and an Arduino uno. To format the drive I have used Trendy Co SDFormatter with the following settings: Format type: Full overwrite, Format size adjustment on. That did not work. I then tried Tuxera Inc with the formatting options Overwrite format. Same story. The CardInfo.ino program worked, but the createDeleteFile.ino did not. I have formatted an 8gb drive and the CardInfo.ino program will not work.
Any hints.
Thank you
tom

Re: SD card not recognised - datalogger shield
Well, your hardware is working, since the program is reporting that the SD was initialized successfully:
What version of Arduino are you using? Are you using a Uno?
Try this - it's the same program, except it writes some data to the file before closing it. I don't know - see if it makes a difference. Otherwise, try a different SD card.
Code: Select all

Re: SD card not recognised - datalogger shield
The pertinent lines from the program you recommended
myFile = SD.open("example.txt", FILE_WRITE);
char message[] = "this is some data";
myFile.write(message, strlen(message));
myFile.close();
results in the following messages
Initializing SD card...initialization done.
example.txt doesn't exist.
Creating example.txt...
example.txt doesn't exist.
Removing example.txt...
example.txt doesn't exist.
I found another program called ReadWrite.ino with the following pertinent lines
myFile = SD.open("test.txt", FILE_WRITE);
if (myFile) {
Serial.print("Writing to test.txt...");
myFile.println("testing 1, 2, 3.");
// close the file:
myFile.close();
Serial.println("done.");
} else {
// if the file didn't open, print an error:
Serial.println("error opening test.txt");
}
Resulting with the following messages
Initializing SD card...initialization done.
error opening test.txt
error opening test.txt
The board model of the ARDUINO is UNO R3.
The two cards I am using are:
2GB MicroSD
8GB MicroSD with the following extra information “Strontium NITRO 400X HC I”: Used in my video camera. I find it odd that this SD does throws an initialization error.
My next video card is a 16GB micro with the following extra information “Transcend Premium 400X HC I”. Using this card results in the following information from the cardInfo program.
Initializing SD card...Wiring is correct and a card is present.
Card type: SDHC
Could not find FAT16/FAT32 partition.
Make sure you've formatted the card
The first two cards I have used the formatting tools as previously described. The last card has 14.1GB used, that is videofiles, and 789MB free.
All three SD cards, inserted into my windows computer, report having FAT32 partitions. However, the cardInfo program reports the smallest card, 2GB, to have a FAT16 partition.
myFile = SD.open("example.txt", FILE_WRITE);
char message[] = "this is some data";
myFile.write(message, strlen(message));
myFile.close();
results in the following messages

Re: SD card not recognised - datalogger shield
Can you just format one of them in the regular windows file explorer? There's something going on with your formatting.

Re: SD card not recognised - datalogger shield
Well, the system itself works. I think there's something wrong with your 8GB card.
Please be positive and constructive with your questions and comments.
