Incorrect FSINFO trail signature in format function

[coran21]

Hello,

I believe the FSINFO trail signature 0xAA550000 is incorrectly stored in the buffer written to the media during the format function.

        /* Build the final signature word, this too is used to help verify that this is a FSINFO sector.  */
        byte_ptr[508] =  0x55;
        byte_ptr[509] =  0xAA;

According to the documentation:

---

FSI_TrailSig 508 4

Value 0xAA550000. This trail signature is used to validate that this is, in fact, an FSInfo sector. Note that the high 2 bytes of this value—which go into the bytes at offsets 510 and 511—match the signature bytes used at the same offsets in sector 0.

---

So, I believe that the correct code should be:

        /* Build the final signature word, this too is used to help verify that this is a FSINFO sector.  */
        byte_ptr[510] =  0x55;
        byte_ptr[511] =  0xAA;

Also, after I formatted the medium and checked it with fsck, I got this message:

FSINFO sector has bad magic number(s):
  Offset 508: 0x0000aa55 != expected 0xaa550000

Are there any plans to continue with development/bug fixing of Filex?

Thanks,

Petr
