Hidden temptation in FDISK

I believe that everyone is very familiar with FDISK. Although FDISK has English interface or does not support large-capacity hard disk partitioning, FDISK is still the preferred partitioning program for many computer enthusiasts. In view of the fact that the partition operation is a re-division of the disk structure, there is a certain danger, so all the parameter switches of the program are not fully disclosed, and the function of the FDISK is limited to a certain extent. Through long-term data collection and practice, the author has obtained a part of the undisclosed parameter switch about FDISK. I will introduce it to everyone and hope that friends can make better use of FDISK.

The general syntax of the command line format of FDISK program is: FDISK /parameter switch, the following are their specific function description:

/ACTOK

Parameter function: Do not check the disk surface Is there a bad sector? It can partition the hard disk without detecting whether there is a bad area on the disk surface.

/CMBR

Parameter Function: Re-establish the description of the master boot record function of the specified disk. Its operation is equivalent to the /MBR parameter, except that the disk can be specified.

/EXT

Parameter Function: Create an extended partition on the current disk (used to create a logical disk partition later).

/FPRMT

Parameter Function: Ask about the use of FAT16 or FAT32 in interactive mode. When the /FPRMT parameter is added, the query screen for supporting the large-capacity hard disk does not appear. Instead, the FAT16 or FAT32 format is used each time a new partition is created, so that we can more freely divide the format of each disk. Of course, it is not very practical now, so everyone has seen it.

/LOG

Parameter function: Create a logical partition of the disk, use /LOG to create a logical disk, /LOG must be used simultaneously with /EXT.

/LOGO

Parameter Function: Create a logical partition of the disk using the FAT16 format.

/MBR

Parameter Function: Re-establish the master boot record of the master disk. After uninstalling Windows NT or Windows 2000, the system boot selection recorded on the master boot record is eliminated; when a virus infects the master boot record, it is quite effective to clean the virus.

/PRI

Parameter Function: The primary partition is created on the disk, and the partition is automatically set to the active form.

/PRIO

Parameter Function: Create the primary partition using FAT16 format and set it to active form.

/Q

Parameter function: Using the /Q parameter will not restart the computer after changing the partition table. This is also a more useful function, if you still need to run after running FDISK For other software, remember to use this parameter.

/STATUS

Parameter Function: When there is no logical partition on the disk expansion partition, the extended partition will not be displayed.

/X

Parameter Function: Using the /X parameter will not result in a partition with LBA attributes.

Among these parameters, /ACTOK, /MBR, /Q are the most common and practical. In general, these parameters will make the FDISK program more comprehensive, but the hidden parameters have a high risk factor, so you should use it with caution.
