DRIVE COMMAND SET MODE SENSE (1AH) Number of Blocks The Number of Blocks field value is zero for the LaserDrive. This specifies that the block length specification that follows applies to the entire media. Block Length The Block Length field specifies the length in bytes of each logical block of the LaserDrive logical unit. The Block Length returned is 400H (1024) bytes. Blocks of parameters called pages follow the block descriptor. Each page is preceded by a header of 2 bytes defining the Page Code and the length of the parameters that follow. The PS bit indicates the page can be saved to nonvolatile RAM. Following the header, pages consist of a number of fields of related flags and/or values. The PS bit in the first byte of each page indicates that the page can be saved to nonvolatile RAM, if set. Savable pages are optional and identified by the PS bit that is returned in the page header by the MODE SENSE command. The Parameter Length indicates the number of bytes that the LaserDrive supports in each Page. The Parameter Length value does not include the 2-byte header. The LaserDrive returns, in the pages of the MODE SENSE commands, the entire page as defined in this document. Valid Page codes are described in the next section. MODE SENSE PAGES The following pages can be returned for a MODE SENSE command as specified by the PF bit and Page Control (PC) field. READ-WRITE ERROR RECOVERY PAGE The Read-Write Error Recovery page specifies the error recovery parameters the Target uses during any command that performs a Read or Write operation to the media. Read-Write Error Recovery Page BIT 7 6 PS (1) Reserved 5 4 3 2 1 0 DTE Reserved BYTE 00 Page Code (01H) 01 02 Parameter Length (2) AWRE (1) 03 Reserved EER (1) PER Read Retry Count (Default 16) PS The PS bit is set to indicate this page can be saved. The default value for byte 2 is 88H. Read Retry Count The Read Retry Count field will always return 16. Refer to MODE SELECT, Read-Write Error Recovery Page section for the selectable field definitions. PLASMON L M S - LD 6100/LF 6600/LF 6602 SCSI INTERFACE SPECIFICATION Page 78
