Aha... well seen ! it could be the bug..
_BUT_ I just tried now, and the invalid FAT still appears...
But thanks for the tip !!
Just 1 question : I've started learning ATA manipulation, FAT16&FAT32
structures and LFN;
The thing I can't figure is :
To search for the content of a given file, the method :
Byte 0 : MBR => Byte 0x7E00 (sector 63) : PBR / Boot sector => Byte 0xBE00
(start + 32 * res_sector ) : FAT table / root dir
Here we get every file's cluster list, right ??
But how can we make link between those cluster list with the file names ???
