== Description ==
The DISK Media Maintenance program is used to format, initialize and verify SCSI disks connected to the ND-100 SCSI host adaptor<ref>[[ND-210523G]] program description, page 15</ref>.

== Target Devices ==
The program is designed to handle the
* Micropolis 1375 SCSI disk drive
* CDC EMD 97201 SCSI disk drive
(valid for DISK-MM-B00)

== Commands ==
>SELECT-DEVICE <Adaptor> <Id number>
This command will select a device for use by other commands. Commands that uses a device for operations will ask for it if it is not defined by this command.

Legal answers for adaptor are:
* Adaptor name (ADAPTOR-n, n=1:4).
* Adaptor number (1:4).
* Logical device number for adaptors data field (2202B:2205B).
* Hardware device number for adaptor (144300B, 144400B, 144500B, 144600B).

Legal answers for ID numbers are 0:7. ID number 7 is normally the SCSI host adaptor, and ID 0 is normally equivalent to "DISC-SCSI-1" which is the boot disk.

The default adaptor is "ADAPTOR-1" or the last selected adaptor, and the default ID is "0" or the last selected ID number.

>CONVERT-DISK-ADDRESS <Address type> <Address>
This command will convert a disk to different address modes and and numeric systems.

The address type could be "Media", "Logical-SINTRAN" or "page".
; Media address : A media address is the address used on basis of the disk drives sector size.
; Logical-SINTRAN : A logical-SINTRAN is the address used on basis of SINTRAN's block size, which always is 1024 bytes/sector.
; Page : A page address is the address used on basis of SINTRAN filsystem's block size, which always is 2048 byte/sector.

>FORMAT-INITIALIZE
Formats and initializes the disk.

Special for Micropolis 1375:

Before format starts, MODE-SENSE default page 3 and 4 is set to current, and cylinder skew and track skew is optimized.

>INITIALIZE
Prepares the disk for use under SINTRAN.

>LIST-DISK-INFORMATION
This command will print out various static and dynamic information conserning the selected disk.

>LIST-PARAMETERS
This command will print out the setting of all parameters available in the command "SET-PARAMETERS".

>LIST-REASSIGN-TABLE
This command will print out all sectors reassigned with the command "REASSIGN". The sectors is listed in historical order.

>LIST-REFRESH-TABLE
This command will print out all sectors refreshed with the command "REFRESH-DATA". The sectors is listed in historical order.

>REASSIGN <Media address>
This command will reassign one single sector and its data on the disk to a different physical area, but to the same logical area.

>REFRESH-DATA <Media address>
This command will try to read one sector and write it back trying to cure temporary parity errors.

>SET-PARAMETERS <Parameter> <Value>

>VERIFY <From> <To>
Data verification. The addresses are given in media blocks. Default range: <0, LastBlock>.
