Dear all, 
I listed fisrt 90 bytes of my FAT32 bootsector.
Before resize
EB 58 90 4D 53 44 4F 53 35 2E 30 00 02 10 20 00
02 00 00 00 00 F8 00 00 3F 00 FF 00 3F 00 00 00
9A E5 3F 01 F3 27 00 00 00 00 00 00 02 00 00 00
01 00 06 00 00 00 00 00 00 00 00 00 00 00 00 00
80 00 29 ED F5 B5 BC 4E 4F 20 4E 41 4D 45 20 20
20 20 46 41 54 33 32 20 20 20

After resize
EB 58 90 4D 53 57 49 4E 34 2E 31 00 02 10 36 00
02 00 00 00 00 F8 00 00 FF FF FF FF 3F 00 00 00
96 AB 7D 01 B0 2F 00 00 00 00 00 00 02 00 00 00
01 00 06 00 00 00 00 00 00 00 00 00 00 00 00 00
80 00 29 ED F5 B5 BC 4E 4F 20 4E 41 4D 45 20 20
20 20 46 41 54 33 32 20 20 20

Parted seem modify some bytes of BPB.
Such as "Reserved Sectors", "Sectors Per Track",
"Number of Heads"...:p

Best Regards, 
Edward
