格式化"轨迹0坏"软

这一计划是用于那些floppies格式有坏道的轨道0时都是以格式化或民政视窗、 显示错误讯息,如"轨迹0不好". 但是你也可以用它来格式正常floppies.

编码的节目已经在磁盘上的名字列入本书"ttformat.c". 工作程序是一样的逻辑节目出版pcquest电脑杂志2003年2版.

在这个节目里,我们设法使这种floppies重用的格式化. 听你的节目可以处理甚至有的软盘坏道而已. 但是,如果第一部分是坏的磁盘,不能格式化软盘.

所有节目改写布拉格反射,脂肪和根目录信息. 如果有坏道的磁盘的表面,他们是标明为坏脂肪.

在编码方案,采用结构溴酚蓝的作家的BIOS参数块的对比. 结构boot_sector用来写布拉格反射的磁盘. address_field用于结构相互作用汽缸数首长、 与同行业平均规模的田径界.

采用不同功能的编码方案及其说明已考虑在下次表.

Function功能

Description描述

Random_VolumeID( )random_volumeid()

This function provides the volume ID of the disk.这项功能提供了磁盘数量身分. (How DOS generates the serial number of the floppy has been discussed next to this table)(民政怎样产生的软序号本表中已讨论过旁边)

mark_bad( )mark_bad()

Mark bad sector using function 04H of INT 13H to verify the sectors.职能部门用坏了4小时39马克43*部门核实.

sector_no_to_physical( )sector_no_to_physical()

This function is used to Convert the number of sectors into tracks, Heads and sectors这项功能是用来跟踪转换成若干部门,主管部门和

format_term( )format_term()

To terminate the formatting and exit the program终止格式化出境程序

write_boot_info( )write_boot_info()

Writes the boot sector of the disk写入引导扇区的磁盘

set_media_type_for_format( )set_media_type_for_format()

The function is used to Set Media Type For format using function 18H of INT 13H媒体的功能是用来确定使用功能型格式和中国科学院的反应18h43

volume_label( )volume_label()

The function gets the volume label to write volume label of the disk商品标签的功能得到写盘量帽子

format( )格式()

Wipes the surface of the disk during formatting as well as handling the bad sectors count.抹面以及格式化的磁盘在处理坏道计数.

get_drive_parameters( )get_drive_parameters()

The Function uses INT 13H, Function 08H to get drive parameters.中国科学院43利用功能,使驾驶功能漏报参数.

mark_bad( )mark_bad()

Holds the information of bad cluster to mark in FAT不良信息联网举行纪念脂肪

ask_for_continue( )ask_for_continue()

Function to confirm before formatting the disk磁盘格式化前确认功能

check_bad( )check_bad()

Function to check if the returned status is error code for BAD sector返回功能检查各部门的地位误码坏

error( )误差()

This function Displays Error message for Corresponding error code这项功能展示错误讯息错误码对应

lock_volume( )lock_volume()

The function is used to lock the Drive using INT 21H, function 44H and Sub function 0DH该功能是用来锁定驱动用*21H条,分置于功能功能0dh

unlock_volume( )unlock_volume()

The function is used to unlock the Drive using INT 21H, function 44H and Sub function 0DH开锁的功能是用来驱动用*21H条,分置于功能功能0dh

physical_to_sector_no( )physical_to_sector_no()

Function is used to Calculate number of sectors from track, head and sector number功能是用来计算一些行业的轨道,一些部门和头部

序号数量计算的软盘按现行民政系统时钟日期和时间.

第一部分序号总和计算时间(红印花一、二秒)和日期(每月一天). 第二部分是序号等于时间(小时和分钟)、日期(年).

所有演出十六进制计算. 例如,让我们假设你格式化的软环境,在国务院关于10/23/2003.11:16:28:65 现在让我们计算磁盘序号.

时间(秒、红印花秒钟)格式
= (28 and 65)
= (1CH and 41H)
Write it as 1C41

同样,日期(每月一天)格式
= (10 and 23)
= (0AH and 17H)
Write it as 0A17

同样,时间(小时、分钟)格式
= (11 and 16)
= (0BH and 10H)
Write it as 0B10

而今年将
= 2003
= 07D3

现在,让我们计算的序号软盘,根据描述过. 第一部分是序号(1c410a17+)=2658而第二部分的序号会(07d30b10+)=12e3.
