6.1.10 NOP – 00H
This command always fails with the device returning command aborted.
6.1.11 Read-Buffer – E4H
The Read Buffer command enables the host to read the current contents of the device’s sector buffer.
This command has the same protocol as the Read Sector(s) command.
6.1.12 Read DMA – C8H or C9H
This command executes in a similar manner to the READ SECTOR (S) command except for the following:
During the DMA transfer phase of a READ DMA command, the device shall provide status of the BSY bit
or the DRQ bit until the command is completed. At command completion, the command block registers
contain the cylinder, head and sector number (LBA) of the last sector read.
If an error occurs, the read terminates at the sector where the error occurred. The flawed data is pending
in the sector buffer. Subsequent sectors are transferred only if the error was a correctable data error. All
other errors cause Read-DMA to stop after transfer of the sector that contained the error.
For Ultra-DMA mode, if a CRC error is detected during transfer, the ICRC and ABRT bits of the Error
register are set at the end of the command.

The host initializes the DMA channel prior to issuing the command;
Data transfers are qualified by DMARQ and are performed by the DMA channel;
The device issues only one interrupt per command to indicate that data transfer has terminated and
status is available.
