SD Card Instant erase

mosquito56

I was trying to get a setting from the sd-card and it just stopped working. I· tried the fsrw_test and got error
-20.
I removed it from the prop and put it on the windows pc. It said drive not formatted. I reformatted in FAT and copied the files from thumbdrive backup to the sd card and it works fine.
· Anyone ever had this happen before?
I have been using the card for almost a week now and never had any problems. I am using Ucontroller SD card reader.

Did you not close a file maybe?

Hi Mosquito.

Closing the file or turning power off whilst the card is trying to respond
causes fatal error like that..
The Olympus digital camera's that use a small XD (miniSD format) are notorious
re this exact issue.. I personally think there is a bug in their OS(Olympus)
.. there are many discussions re this exact issue on the net
people loosing all their holiday pictures.. etc etc...

A program that smashes memory could cause this. (If it smashes the memory location that indicates what block the current unwritten FAT entry
is stored at, that could do it.)

It's also possible you've uncovered a use case that exhibits a bug.

Considering the program was constantly opening, reading and reseting the startup value, it's very possible I unplugged the chip at a bad time. Thanx will be a little more careful in future.
