Why can t my computer recognize partition 2 after partitioning the USB flash drive?

Maybe it's written protection! You use someone else's computer to format the USB flash drive! Then try again!

After distinguishing, you also need to load him and assign a drive letter!

It is recommended that you use ghost to partition it, so that it can be displayed directly.

I have the impression that these partitioning software cannot be directly divided into USB flash drives, and mass production tools must be used.

At least that's how my Kingston got it.

Partition: A portion of a physical disk that acts as a physically delimited unit. A partition usually refers to a primary partition or an extended partition. The following is the solution to the problem that I can't recognize after the computer hard disk I collected and sorted, welcome to read.

1. Right-click "My Computer" and select Open Management;

2. Click "Disk Management" in the left menu, you can see the newly added hard disk (disk 0 in the picture);

3. Click on this new hard disk, it will automatically open the initialization disk window, if the disk capacity is greater than 2T, select GPT, return it, select MBR;

4. After the initialization is completed, start the disk partition, right-click on the blank space on the right side of the disk, and select "New Simple Volume".

5. Click Next;

6. Set the size, drive letter, and format of the partition, such as 50G'NTFS format partitions;

7. Click Done, so that there will be a 50G K disk;

Note: The remaining capacity can be partitioned according to the above method, it is recommended not to build too many partitions, and about 3 partitions for 1t are OK.

The above is the introduction of the computer after installing a new hard disk but not showing and partitioning the newly installed hard disk, friends with the same problem can follow the above methods to solve.

In Windows Disk Management, delete the partition and reset it.

This is Microsoft's work. In Windows, U disk and mobile hard disk are treated differently, the hard disk can be partitioned, but the U disk can not be partitioned, if you use special partitioning software to partition the U disk, Windows only recognizes the first partition, and the subsequent partition is not recognized. Linux supports the partitioning of USB flash drives, USB flash drives and mobile hard disks are treated the same, and the partitions of USB flash drives can be identified in Linux.

If you want to use a multi-partition USB flash drive in the Windows operating system, you need to use mass production tools to mass production, first check the main control used by your USB flash drive, different master control solutions use different mass production tools, which is more troublesome, and mass production tools are not easy to get. Note that mass production will delete all data on the USB flash drive, please back up your files before mass production.

PS: It seems that there is also software that can switch the partition that can be recognized by Windows by switching the USB flash drive to activate the partition, but it can still only recognize one partition at the same time. As for the name of the software, I can't remember clearly, I've seen it on the Internet before, it seems to be bootice, you can hide a certain partition to protect files from access and changes, and switch it when you need to access it, I haven't used this feature.

It is better not to partition the USB flash drive, which is prone to problems.

Take win7 as an example: right-click "Computer" - "Management" - "Disk Management".

Check whether there is any unallocated space in the disk area, if you have partitioned it through the partition tool, then there is an unknown state of expansion partition in the disk expansion partition, then as long as the extended partition is formatted one by one, it can be used normally (remember to format it in NTFS file system format). Sometimes, if you format the extended partition to FAT format when partitioning, you will not be able to see the partition drive letter, which is the same as reformatting the extended partition (into the partition such as d e f) to the ntfs file system format.

But if you don't have unallocated disk space in your disk area, then your disk won't actually have a partition at all.

After partitioning, you need to format and assign a drive letter to unhide before it can be displayed.

Right-click on My Computer on the desktop, select Management, find Disk Management, and format the partitioned disk partition.

My Computer (right-click) - Disk Management - Attach all partitions.

Problem Analysis:

First of all, we know that the first time we install the system, we can recognize the disk drive letter, which is caused by the forced restart of the computer during the installation process, so it is possible that there is a problem with the main boot of the hard disk, so we can rebuild the master boot record to solve the problem.

Problem solved: 1. Restart the computer, after entering the U boot PE system, double-click to open the Diskgenius partition tool, and then click "Hard Disk - Rebuild Master Boot Record (MBR)".

2. Then, click "Yes" in the pop-up window, and close the tool after the task is completed.

3. At this time, re-open the "U Start PE One-click Installation" to identify the disk letter.

At this point, the solution to the problem of not recognizing the disk caused by force restarting the computer in the process of reinstalling the system is finished, if the above methods still cannot solve this problem, you may wish to try to use a hard disk regenerator and other hard disk maintenance tools to try to fix it.

It is best not to operate directly on this hard disk, find another computer, this hard disk is connected to the disk, copy the data out, and then re-partition the hard disk, this operation method is safer.

There are 2 cases.

1. There is a problem with that disc: the solution, buy a new one.

2. Hard Disk Partition Table Corruption: There may be some repair software on the disk on which the system is installed, which can be used to repair it. If it can't be repaired, enter the Windows PE system of the CD, copy the important data from the hard disk to the U disk after entering (you have to have a U disk first), and then, the whole disk is quickly partitioned, only repartitioning and reinstalling the system, if the fast partition is still not installed in the system, it should be divided several times, because it should be.
