UL/CSA/VDE/TUV UL standard 1950 3rd Edition recognition granted under File No. [. . . ] The maximum value allowed is the total number of initiator-addressable logical blocks for the value specified in the Block Length field. A value that is less than the maximum value will decrease the number of initiator-accessible logical blocks to the amount specified. The value in this field specifies the length, in bytes, of each block. Description Block Length 5. 14. 1 Read-Only Mode Pages Table 5-93 lists read-only mode pages.

A PS bit value of 1 indicates that the disk drive is capable of saving the page in a non-volatile vendor specific location. The value depends on the Notch value selected in the Notch and Partitions page. The number of physical sectors between the last logical sector on one track and the first logical sector on the next track within a cylinder. The number of physical sectors between the last logical sector on one cylinder and the first logical sector on the next cylinder. A Surface bit value of 0 indicates that the drive allocates progressive addresses to all logical blocks within a cylinder prior to allocating addresses on the next cylinder. 5-68 Maxtor Atlas 10K V 5. 14. 3 Rigid Disk Geometry Page (04h) The Rigid Disk Geometry Page describes the drive geometry. The data format and field descriptions are described in Table 5-96 and Table 5-97 respectively.

A returned value of 1 indicates that the target is capable of saving the page in a non-volatile, vendor-specific location. The value in this field is the physical cylinder at which write precompensation is to begin. If the starting cylinder is equal to the value in the Number of Cylinders field, write precompensation is disabled. The value in this field is the physical cylinder at which write current is reduced. If the starting cylinder for reduced write current is equal to the value in the Number of Cylinders field, reduced write current is disabled. This field indicates a two's complement location where the drive positions the disk heads. A negative value indicates that the heads are positioned below cylinder 0 by that number of cylinders. A positive value greater than the number of cylinders indicates that the heads are positioned beyond the cylinders used for data storage at the location specified. Rotational Position Locking is used for spindle synchronization in storage arrays. The modes are: 00b ­ Disabled 10b ­ Master 01b ­ Slave 11b ­ Not supported RPL can be overridden if the Maxtor (Vendor) Special Function Control page Auto field value = 1. Rotational Offset indicates the amount of rotational offset that the drive uses when synchronized. [. . . ] THIRD-STROKE SEEK ­ A method of evaluating the power requirements of a hard drive. It involves monitoring drive current while seeking to a selected track, waiting for 1/ 2 a revolution, then seeking to a track that is 1/ 3 of the total actuator stroke from the first. The number of tracks written within each inch of disk's surface, used as a measure of how closely the tracks are packed on a disk surface. TRACK ­ One of the many concentric magnetic circle patterns written on a disk surface as a guide for storing and reading data. [. . . ]
