Page 21: Product Specification Outline
OEM MANUAL:K6602924 PRODUCT SPECIFICATION OUTLINE This chapter describes the logical subjects of Product Specification. Refer to the Product Specification for physical information which are not included herein. ADDRESSING The host computer addresses the target logical unit (controller and drive) using the methods described below.
Page 22: Format Processing
OEM MANUAL:K6602924 · Control parameters (MODE SELECT, INQUIRY and LOG) · Defect list (manufacture and grown) · Control program (Downloadable Firmware) etc. The data in system area is duplicated for data integrity. The user area consists of the diagnostic cylinder, the data area. The user area, except the data area, may not be accessible from the host computer.
Page 23 OEM MANUAL:K6602924 (2) Alternate Spare Area The controller allocates 10 local alternate cylinders per notch as an Alternate Spare Area for the defective sector. Defect Management Defect management is the assignment of alternate spare sectors for defective sectors caused by media flaws. The host computer may access the data block as defect-free media by the defect management.
Page 24: Figure 2-1 Track Skew (Skew Factor N)
OEM MANUAL:K6602924 Figure 2-1 explains the details of Track Skew. Sector Sector Number Head 0 Head 1 n sectors Figure 2-1 Track Skew (Skew Factor n) Cylinder Skew The controller implements Cylinder Skew which shifts the sector array between cylinders ( i.e., between the last track of a cylinder and the first track of the next cylinder) to avoid a rotational latency when a 1 track seek is performed.
Page 25: Figure 2-3 Sector Reallocation
OEM MANUAL:K6602924 The replacement sector is assigned to the next defective sector, to reduce rotational latency. The controller executes a verification after formatting if C scheme is specified. If an error is found, the controller identifies the error sector as defective and reformats the track and the cylinder.
Page 26: Error Retry
OEM MANUAL:K6602924 · It is suggested to specify P, G and C schemes ( i.e., to use Primary and Grown lists, and to execute verify processing ) when specifying defect management. · The D scheme of defect management is not necessary for normal operation. Since the controller automatically reads P and G lists in system area and formats medium, the host computer does not need to specify the defect.
Page 27: Verify Error Retry
OEM MANUAL:K6602924 2.3.3 VERIFY ERROR RETRY The controller performs the same retry as the read error retry mentioned in section 2.3.1 READ ERROR RETRY for the verify error during the verify operation. The host computer can change the error management of the controller with the verify error recovery parameter (Page Code 7 H ) of the MODE SELECT command.
Page 28: Supported Scsi Commands
OEM MANUAL:K6602924 ·However, if the error in the data field is correctable by ECC the controller corrects the error using ECC, and terminates the recovery procedure (this is applicable when EER=1). Retry Count The host computer can select the retry count by specifying the counts to the retry count field of the error recovery parameter.
