Description: 软盘的FAT表(文件分配表)被损坏时,计算机就不能从软盘上读取数据。 但是,在软盘中有两份完全相同的文件分配表,而DOS在读文件时并不使用 第二张文件分配表,因此,它被损坏的可能性较低。在计算机提示FAT表损 坏时,利用第二张分配表重写第一张文件分配表,往往能成功地挽回你的软 盘上的数据。文件分配表在磁盘中的具体位置及长度视磁盘的规格不同而 不同。 本文提供的程序,用Turbo C 2.0编写,于Dos6.22,UCDOS 3.1下通过。 按照程序的提示,可方便地完成这一工作。-floppy FAT (File Allocation Table) were damaged, the computer is not possible to read data on the floppy. However, the floppy disk is identical to the two File Allocation Table, and DOS when reading the document does not use the second-File Allocation Table, therefore, it was the possibility of damage to the lower. The computer table suggested FAT damage, the use of a second table to rewrite the first File Allocation Table, often successfully restore your data on the floppy disk. File Allocation Table disk in the specific location and length depending on the disk with different specifications. In this paper, the procedures used to prepare Turbo C 2.0, in the shadow, UCDOS 3.1 through. According to the suggested procedure would facilitate completion of this work.

Description: 1．在内存中开辟一个虚拟磁盘空间作为文件存储器，在其上实现一个简单的单用户文件系统。在退出这个简单的文件系统时，应将该虚拟文件系统保存到磁盘上，以便下次可以再将它恢复到内存的虚拟磁盘空间中。 2．文件存储空间的分配可采用显式链接分配或其他的办法。 3．空闲空间的管理可选择位示图或其他的办法。如果采用位示图来管理文件存储空间，并采用显示链接分配方式，那么可以将位示图合并到FAT表中。 4．文件目录结构采用多级目录结构。为了简单起见，可以不使用索引结点，其中的每个目录项应包含文件名、物理地址、长度等.-1.making a virtual diskete memory as file storyge,in this district it can implement a simple single user file system .when quit this simple file system ,it shoud save the virtual file system to diskete,then it can be resumed to virtual diskete district in the memory.3.we can choose location hint map to manage the idle space or orther means.if we choose locationhint map to manage file saving space,and adopt show linking distribution mode,we can combine location hint map into FAT table.4.file directory confiuration adopts multilevel directory confiuration.to simplify,it doesn t use index dot,evrery term shoud include file name,physical dress and lenght.

Description: 此程序的功能为：0。读取mbr信息，取活动分区的dpt（分区表信息），从中取出分区的起始 柱面号，磁头号，扇区号
1。读取DBR字段，从中取出硬盘参数和FAT32文件系统的信息。
2。根据1中的信息，读取C盘根目录区
3。在根目录区中查找要检测的文件名，找到，则取出它的起始簇号和文件长度。
4。根据起始簇号找到此文件对应的扇区和在FAT表中的簇链
5。根据4的信息，控制读取文件的数据（用来做校验和）。
6。检测下一个文件名，重复3-5步-this program functions are to : 0. Mbr read information from the District Assemblies activities (partition table information), remove from the start through cylindrical, head, Sector No. 1. Read DBR fields, removed from the hard drive parameters and the FAT32 file system information. 2. According to one of the information, reading occurs, District 3. The root directory search area to detect the documents were found, it took the initial cluster and length of documents. 4. Under the initial cluster, find this file and the corresponding portion of the FAT table in the cluster chain five.

Description: ucFS的加强版,含完整代码，原版的ucFS不支持长文件名和中文(因为不支持UNICODE).
经本人修改目前已经支持长文件名，长目录名等，同时定义了自己的扩展UNICODE支持，可用于显示中文，日文等文件名。而且对FAT表操作做了处理，将FAT信息放在内存中，有效提高文件FSEEK的速度，已经应用到公司的项目中，对嵌入式应用中随机读写文件效果很明显！-ucFS the enhanced version, with complete code, original ucFS does not support long file names and Chinese (because they do not support UNICODE). After I have been changes to the existing support long file name, directory name, such as long, while the expansion of the definition of its own UNICODE support, available display Chinese, Japanese, such as file name. But also to the FAT table to do a deal with the operation will be FAT information in memory, effectively improve the speed of file fseek, have been applied to the company s projects, of embedded applications in random effects is clear to read and write files!

Description: 硬盘主引导记录程序的功能是读出自举分区的BOOT程序，并把控制转移到分区BOOT程序。整个程序流程如下：
1 将本来读入到0：7C00H处的硬盘主引导记录程序移至0：61BH处；
⑵ 顺序读入四个分区表的自举标志，以找出自举分区，若找不到，转而执行INT18H的BOOT异常执行中断程序；
⑶ 找到自举分区后，检测该分区的系统标志，若为32位FAT表或16位FAT表但支持13号中断的扩展功能，就转到执行13号中断的41号功能调用进行安装检验，检验成功，就执行42号扩展读功能调用把BOOT区程序读入到内存0：7C00H处，成功，跳到第⑸步，若读失败或系统标志为其它，就调用13号中断的读扇区功能调用把BOOT读到0：7C00H；
⑷ 用13号中断的读扇区功能时，用两种方式分别进行5次试读。第一种方式是直接从自举分区的头扇区读入BOOT程序，若读成功，但结束标志不是55AA，则改用第二种方式，又如果用第一种方式试读五次均不成功，就改用第二种方式。若两种方式试读均失败，就转到出错处理程序；
⑸ 读入BOOT区程序成功，转至0：7C00H处执行BOOT程序。 -err
