Title: SD Card Formating
Post by: ATU on July 08, 2019, 02:46:37 PM

I purchased a microSd card from AD, but it unfortunately it was formatted in another device and I am trying to get it back to the original format. I tried to format it in Windows10, but it keeps failing.  I tried to format it in DMD, but I read that it is not supported. Is there something special you have to do to format them for use in the BRX?

Right click on the media/drive in Windows 10 Explorer.

Do NOT do a Quick Format.  Format in FAT32 format.

Remember to Right Click on the media/drive and EJECT from Windows Explorer before removing the media from your PC.

It fails the Windows format right at the end. Yes, the Lock is off. What is the Allocation Unit Size?  I set it for default.

I had some cases where Windows format failed. I used a third party app made by one of the SDCard manufacturers. Sorry, I don't recall which it was.

I've used the tool from the SD Association.

I believe this is the one I used also.
