IBM IC35L040AVVN07-0 - 40GB IDE Deskstar 120GXP 7200RPM UATA-100 07N9682 Specifications page 113

The Write Multiple command transfers one block of data for each interrupt. The other commands transfer
one sector of data for each interrupt.
If the device detects an invalid parameter, it will abort the command by setting BSY=0, ERR=1, ABT=1,
and interrupting the host.
If an uncorrectable error occurs, the device will set BSY=0 and ERR=1, store the error status in the Error
Register, and interrupt the host. The registers will contain the location of the sector in error. The errored
location will be reported with CHS mode or LBA mode; the mode is decided by mode select bit (bit 6) of
Device/Head register on issuing the command.
All data transfers to the device through the Data Register are 16 bits, except for the ECC bytes which are
8 bits.
