Interface Even if an error is encountered, the device prepares for data transfer by setting the DRQ bit. Whether or not to transfer the data is determined for each host.

5.4 Command Protocol IMPORTANT For transfer of a sector of data, the host needs to read Status register (X'1F7') in order to clear INTRQ (interrupt) signal. The Status register should be read within a period from the DRQ setting by the device to starting of the sector data transfer. Note that the - Fujitsu MH2060AH | Manual/User Guide - Page 182
required parameters to the Features, Sector Count, Sector Number, Cylinder, and Device/Head registers. b) The host writes a command code in the Command register.

the Status register does not meet above condition, normal data transfer operation is not assured guaranteed. When the host issues the command even if the drive requests the data transfer (DRQ bit is set), or when the host executes resetting, the device correct operation is not guaranteed.

If a subsequent command requests reading of the read-ahead data, data on the data - Fujitsu MH2060AH | Manual/User Guide - Page 229
6.4 Read-ahead Cache 6.4.2 Caching operation The caching operation is performed only when the commands listed below are received. If any of the following data are stored on the data buffer, the data is sent to the host system. • All of the sector data that this command processes. • A part of the - Fujitsu MH2060AH | Manual/User Guide - Page 230

6.4 Read-ahead Cache 6.4.3 Using the read segment buffer Methods of using the read segment buffer are explained for following situations. 6.4.3.1 Miss-hit In this situations, the top block of read requested data is not stored at all in the data buffer. As a result, all of the read requested data - Fujitsu MH2060AH | Manual/User Guide - Page 232
Operations 6.4.3.2 Sequential Hit When the read command that is targeted at a sequential address is received after execution of the read commands is completed, the read command transmits the Read requested data to the host system continuing read-ahead without newly allocating the buffer for read. - Fujitsu MH2060AH | Manual/User Guide - Page 233
6.4 Read-ahead Cache 6.4.3.3 Full hit In this situation, all read requested data is stored in the data buffer. Transfer of the read requested data is started from the location where hit data is stored. For data that is a target of caching and remains before a full hit, the data is retained when - Fujitsu MH2060AH | Manual/User Guide - Page 234
Operations 6.4.3.4 Partial hit In this situation, a part of read requested data including the top sector is stored in the data buffer. A transfer of the read requested data starts from the address where the data that is hit is stored until the top sector of the read requested data. Remaining part - Fujitsu MH2060AH | Manual/User Guide - Page 235
6.5 Write Cache 6.5 Write Cache Write Cache is the function for reducing the command processing time by separating command control to disk media from write control to disk media. When Write Cache is permitted, the write command can be keep receiving as long as the space available for data transfers - Fujitsu MH2060AH | Manual/User Guide - Page 236
on the data buffer, data of the data buffer is written on the media, and reset processing is then performed. This is true for both a hard reset and soft reset.
