Hard disk error - sector not found - China DOS Union Forum

The following is the statement quoted by Bing Shui Yao on June 9, 2003, 22:51:36:
The hard disk is divided into five parts: MBR (Master Boot Record), DBR (DOS Boot Record), FAT (File Allocation Table), DIR (Root Directory Area), and DATA (Data Area). The appearance of the C drive letter indicates that the MBR is not damaged. The ability to list directories using DIR indicates that the DBR is not damaged. When performing operations on data and encountering the above prompt information, it means that the clusters occupied by these files are marked as bad clusters in the FAT (provided that the disk scanning program has been run, which marks unreadable and unwritable files as bad clusters in the file allocation table). If all operations are not possible, it means that the FAT table has been completely damaged, and the FORMAT formatting command can be used to rebuild it.

Xiao Bing, is the root directory area generally called the ROOT area?
"Being able to list directories using DIR indicates that the DBR is not damaged" Here, "DBR" should be "DIR"?
"Can use the FORMAT formatting command to rebuild it." Format cannot rebuild it?
format is used to format the disk, not to rebuild the partition table. Moreover, it is a very dangerous DOS command that will delete all the files on your disk! Please use it with caution!!
Of course, after formatting a disk with format, it does create a brand-new partition table (if your meaning of rebuilding is like this). But this is an empty partition table with nothing in it...

1. The root directory area is also called the BOOT area, and some also call it the DIR area. Just different names. 2. "Being able to list directories with DIR means the DBR is not damaged". Of course, the DIR area is also not damaged, because the content listed by dir is the content of DIR (or the BOOT you mentioned). 3. What I mean by reconstruction refers to those contents you mentioned. Yes, it is very dangerous. 4. Few people will back up the hard disk partition table and file allocation table, so I suggest he start over!
