DELETE EVERY SINGLE BIT #52

Open toosimit opened 3 years ago

toosimit commented 3 years ago

HI DEAR FIRST, I WANT TO ASK YOU IS THERE ANY WAY TO CLEAR EVERY SINGLE BIT ? SECOND IS THERE ANY WAY TO CHANGE FORMAT ? FAT 12 TO FAT16 OR FAT32 TO NTFS

Hello, first of all it would be nice if you could not use all caps letters as it is regarded as yelling in nettiquette usually...

To your question: There is no format command in this library so no easy single command

BUT

  1. delete all files
  2. delete all folder
  3. get size of sd card getTotalSectors();
  4. write everything with one big random file or just ones like this 111111
  5. write everything with 000000

= SD Card destroyed data and needs format after that

Hi, sorry for late reply, how @Meins321 mentioned, the library does not support a format command and the chip does not support NTFS file system, only FAT12, FAT16, FAT32.
