Servo test routine performs low level formatting individually for each physically present magnetic head. Tracks that cannot be formatted may be added to defects table. This explained in an in section 5.3 Surface Surface scanning means testing of physical parameters of the surface. This command is plained in detail in "Drive surface testing"sectio 5.4 Firmware data Firmware data represents a set of commands for work with drive's firmware Selection of Work with Rom Work with disk firmware zone Load an ldr file to drive ram Spindle stop 5.4.1. Work with ROm Work with ROM command brings up a submenu containing just one option entitled"Read ROM to file", its start requires to enter a name for the file to which ROM will be read 5.4.2. Work with disk firmware zone Work with disk firmware zone is a set of routines meant for work with the portion of drive's firmware recorded on disk surface. Selection of that option brings up the following Check firmware structure Write/read firmy Read configuration pages Write configuration pages Read modules Write modules Detailed COM log Security subsystem 5.4.2. 1 Check firmware structure Check firmware structure command accomplishes reading of all structural units in drive's firmware(modules and configuration pages) and performs their interpretation thus checking them for accuracy. A job report is output in a list form. It can be saved to file by pressing [F2 Firmware checking procedure takes several minutes. That is caused by the presence of unused modules with unformatted sectors in the firmware zone 5.4.2.2 Write/read firmware Write/read firmware is a set of commands that allow to create a database file containing drives firmwareServo test routine performs low level formatting individually for each physically present magnetic head. Tracks that cannot be formatted may be added to defects table. This explained in detail in Section 8.1. 5.3 Surface scanning. Surface scanning means testing of physical parameters of the surface. This command is explained in detail in “Drive surface testing” section. 5.4 Firmware data. Firmware data represents a set of commands for work with drive’s firmware. Selection of that option brings up the following menu: Work with ROM Work with disk firmware zone Modification of configuration Load an LDR file to drive RAM Spindle stop 5.4.1. Work with ROM.
