Hi,

Is this known problem? Any idea?

Thanks.

Thanks for good testing.

First of /dev/sda1 contains the valid FAT format. But it appears on
offset of 0x5000.

0000000    0000    0000    0000    0000    0000    0000    0000    0000

0005200    fff8    ffff    ffff    ffff    0000    0000    0000    0000

0x5000-0x5200 is the valid FAT format for 128MB.  These must be on
offset of 0x0-0x200.
