Verify Error Recovery Parameters (Page Code = 7) - Fujitsu MAX3073NC - SCSI,80, Dell DC961,Hard Drive Scsi Logical Interface Specifications

a. Cylinder count
This parameter specifies the total number of cylinders configured in the user space on the disk
media. This value includes the number of cylinders for alternate blocks specified in the "Alternate
Track Count/Drive" parameter of the format parameters (Page code = 3).
It is impossible to change this parameter.
b. Number of heads
This parameter indicates the number of data Read/Write heads in the disk drive. It is impossible to
change this parameter.
c. Bytes 6 to 16
The parameter defined in bytes 6 to 16 of this page descriptor is a parameter that it is clearly not
necessary for the INIT to specify. The IDD disregards the values specified in this field.
d. RPL (rotational position locking)
These bits are used for rotational synchronization of the disk and can be specified. The IDD
disregards the value specified in this field.
e. Rotational synchronization offset
This is a field which specifies the offset value used for rotational synchronization of the disk, but it is
not supported in the IDD. The IDD disregards the value specified in this field.
f. Rotational speed
This specifies the disk's rotational speed in rpm (rotations/minute). This parameter cannot be
changed by the INIT. The IDD disregards the value specified in this field and operates according to
the "Default" value.
