The format is patterned after the termi- nal data base. Entries in consist of a number of fields separated by colons (:). The first entry for each disk gives the names that are known for the disk, separated by vertical bars (|). The last name given should be a long name fully identifying the disk. The following list indicates the normal values stored for each disk entry: Name Type Description ns num Number of sectors per track nt num Number of tracks per cylinder nc num Total number of cylinders on the disk ba num Block size for partition `a' (bytes) bd num Block size for partition `d' (bytes) be num Block size for partition `e' (bytes) bf num Block size for partition `f' (bytes) bg num Block size for partition `g' (bytes) bh num Block size for partition `h' (bytes) fa num Fragment size for partition `a' (bytes) fd num Fragment size for partition `d' (bytes) fe num Fragment size for partition `e' (bytes) ff num Fragment size for partition `f' (bytes) fg num Fragment size for partition `g' (bytes) fh num Fragment size for partition `h' (bytes) pa num Size of partition `a' in sectors pb num Size of partition `b' in sectors pc num Size of partition `c' in sectors pd num Size of partition `d' in sectors pe num Size of partition `e' in sectors pf num Size of partition `f' in sectors pg num Size of partition `g' in sectors ph num Size of partition `h' in sectors se num Sector size in bytes ty str Type of disk (e.g. removable, winchester) The entries can be automatically generated with the program.
