I tried to format the disk and after that even PC cannot find its partition
info.
Yes. I do include the supprot for the FAT FS.
I traced the code and it seems that the driver cannot get the correct data
of the first sector. I compared the data of the first sector from USB 1.1
port and USB 2.0 port, they are different even though I use the same USB
memory stick. The code failed at
if (*(WORD *)(pSector + BOOT_SIGNATURE) == BOOTSECTRAILSIGH) in
GetDOSPartitions function.
The data from USB1.1 port contains 0xaa55 which is BOOTSECTRAILSIGH whereas
the data from USB 2.0 driver doesn't.
I have to figure out why? It seems the driver causes the problem.
