The simplest is to +use the +.Nm +program. +The alternative is to use the DEC standard formatting software which +operates under the DEC diagnostic supervisor. +This manual page describes the operation of +.Nm , +then concludes with some remarks about using the DEC formatter. +.Pp +.Nm +is a standalone program used to format and check disks prior to +constructing file systems. +In addition to the formatting operation, +.Nm +records any bad sectors encountered according to DEC standard 144. +Formatting is performed one track at a time by writing the appropriate +headers and a test pattern and then checking the sector by reading and +verifying the pattern, using the controller's ECC for error detection. +A sector is marked bad if an unrecoverable media error is detected, or +if a correctable ECC error too many bits in length is detected (such +errors are indicated as +.Dq ECC +in the summary printed upon completing the format operation). +After the entire disk has been formatted and checked, the total number +of errors are reported, any bad sectors and skip sectors are marked, +and a bad sector forwarding table is written to the disk in the first +five even numbered sectors of the last track. +It is also possible to reformat sections of the disk in units of +tracks. +.Nm +may be used on any +.Tn UNIBUS +or +.Tn MASSBUS +drive supported by the +.Em up +and +.Em hp +device drivers which uses 4-byte headers (everything except RP's). +.Pp +The test pattern used during the media check may be selected from one +of: 0xf00f (RH750 worst case), 0xec6d (media worst case), and 0xa5a5 +(alternating 1's and 0's). +Normally the media worst case pattern is used. +.Pp +.Nm +also has an option to perform an extended +.Dq severe burn-in , +which makes a number of passes using different patterns. +The number of passes can be selected at run time, up to a maximum of +48, with provision for additional passes or termination after the +preselected number of passes. +This test runs for many hours, depending on the disk and processor. +.Pp +Each time +.Nm +is run to format an entire disk, a completely new bad sector table is +generated based on errors encountered while formatting. +The device driver, however, will always attempt to read any existing +bad sector table when the device is first opened. +Thus, if a disk pack has never previously been formatted, or has been +formatted with different sectoring, five error messages will be +printed when the driver attempts to read the bad sector table; these +diagnostics should be ignored. +.Pp +Formatting a 400 megabyte disk on a +.Tn MASSBUS +disk controller usually takes about 20 minutes. +Formatting on a +.Tn UNIBUS +disk controller takes significantly longer. +For every hundredth cylinder formatted +.Nm +prints a message indicating the current cylinder being formatted. +(This message is just to reassure people that nothing is amiss.) +.Pp +.Nm +uses the standard notation of the standalone I/O library in +identifying a drive to be formatted. +A drive is specified as +.Em zz(x,y) , +where +.Em zz +refers to the controller type (either +.Em hp +or +.Em up ) , +.Em x +is the unit number of the drive; 8 times the +.Tn UNIBUS +or +.Tn MASSBUS +adaptor number plus the +.Tn MASSBUS +drive number or +.Tn UNIBUS +drive unit number; and +.Em y +is the file system partition on drive +.Em x +(this should always be 0). +For example, +.Dq hp(1,0) +indicates that drive 1 on +.Tn MASSBUS +adaptor 0 should be formatted; while +.Dq up(10,0) +indicates that +.Tn UNIBUS +drive 2 on +.Tn UNIBUS +adaptor 1 should be formatted. +.Pp +Before each formatting attempt, +.Nm +prompts the user in case debugging should be enabled in the +appropriate device driver. +A carriage return disables debugging information. +.Pp +.Nm +should be used prior to building file systems (with +.Xr newfs 8 +to ensure that all sectors with uncorrectable media errors are +remapped. +If a drive develops uncorrectable defects after formatting, either +.Xr bad144 8 +or +.Xr badsect 8 +should be able to avoid the bad sectors. +.Sh EXAMPLES +A sample run of +.Nm +is shown below. +In this example (using a +.Tn VAX-11/780 ) , +.Nm +is loaded from the console floppy; +on an 11/750 +.Nm +will be loaded from the root file system with +.Xr vax/boot 8 +following a +.Dq B/3 +command. +Boldface means user input. +As usual, +.Dq # +and +.Dq @ +may be used to edit input. +.Bd -literal -offset 0.5i +>>>\fBL FORMAT\fP + LOAD DONE, 00004400 BYTES LOADED +>>>\fBS 2\fP +Disk format/check utility +.sp +Enable debugging (0=none, 1=bse, 2=ecc, 3=bse+ecc)?
