5.1.20 Write Long Sector – 32h, 33h
This command is similar to the Write Sector(s) command, except that it writes 516 bytes instead of
512 bytes. This command can write only one sector at a time. The transfer consists of 512 bytes of
data transferred in word mode, followed by four bytes of ECC transferred in byte mode. The four
ECC bytes transferred by the host cannot be used by DiskOnChip IDE Pro. The device discards
these four bytes and writes the sector with valid ECC fields.
