The identify device command requests the drive to transfer parameter information to the host. When the command is issued, the drive sets BSY, stores the required parameter information in the sector buffer, sets the DRQ bit, and issues an interrupt. The host may read the parameter information of the sector buffer. The parameter words in the buffer are arranged as shown in Table 11.8-1 ~ Table 11.8-5.
