High-level format
After partitioning the hard disk, some “independent” logical drivers are founded. If now we start system from the floppy drive, enter DOS, then you can see the drive letters of DOS partition, which is on behalf of logical driver, for instance “C:”, “D:” and so on. The system commonly arranges letters according to alphabet. Now let’s try to enter “C:” or “D:” after that we can see the system prompt that “DISK MEDIA ERROR”. Why? These logical disks are empty; to use them, we need create file system. The whole process is high-level format of logic disk. The high-level format certainly aims at the logic disk, neither physical disk nor certain directory. For file system is corresponding to logic disk, we can say that high-level format aims at file system. In this article, logical disk means logical drive.

Format partition
High-level format of DOS logic disk can be completed by “format” command. Main functions of high-level format are as following:

Assign logical serial numbers for sectors (serial numbers in partition) from cylinder that assigned by each logical drive

Establish DBR in basic partition, and load 3 system files of DOS if there is “/S” parameter in the command.

Establish file allocation table (FAT) in each logical disk.

Establish File Directory Table (FDT) that is corresponding to root directory and data area.

If you carry out high-level format by “Format” command, please pay attention to following 4 items.

1. To already activated basic DOS partition (generally it is disk C), you need the following command:

Format C:/s

By this command, you may install DOS system files after high-level format, to make this logical disk to become the boot disk. Certainly, you may also use “SYS” command to send system files after high-level format, that is complete the boot disk and file transmission by the following two commands:

Format C:

SYS C:

Continuously using these two commands equals to “Format C:/S” command.

2. For other logical disk, we only need to carry out the following commands:

Format  [ d:  ]

“d” is the logical disk drive.

3. Before format, on the screen it may appear the following prompt information:

WARNING:  ALL  DATA  ON  THE  DISK
DRIVE  C:  WILL  BE  LOST !
Proceed with Format (Y/N) ? _

This information is warning user: The format will cause all data lose! Then, if user choose “Y”, then the high-level format officially carries on, if user choose “N”, then nothing will happened and exit.

4. For the using disk without adjusting the partition, also may carry on the fast format, the command is:

Format C: /Q
