php Xiaobian Yuzai teaches you how to check the U disk partition format. When using a USB flash drive, it is very important to understand its partition format, which can help you better manage and use the USB flash drive. Different partition formats have different uses and compatibility, helping to avoid data loss and unnecessary trouble. This article will introduce how to quickly check the partition format of a USB flash drive, allowing you to easily grasp the usage of the USB flash drive.
Phenomenon: After the U disk is inserted into the computer, it prompts to format the disk. This happens to every computer when it is inserted, and the U disk partition format becomes RAW format. The U disk displayed in my computer There is no capacity. Even if you double-click the U disk, you are still prompted to format it? Never format, never format, never format.
Right-click My Computer--Manage--Disk Management to check whether the U disk is RAW
Try method one: chkdsk K:\fMany people usually prefer to use chkdsk to repair disk partition problems, but this method may not be effective when the USB flash drive has been converted to RAW format. Therefore, it is recommended not to try to use chkdsk to repair the USB drive that needs to be formatted and is in RAW format.
Try method two: Data recoveryWhen you encounter important data in the USB flash drive that needs to be recovered, do not rush to format it. Formatting can result in data corruption that cannot be recovered. Because these data are very important to me, I tried several recovery tools and found that each tool has different recovery effects.
1. diskgenuis
This is a partition software that everyone is familiar with. In addition to partition management functions, it also has data recovery features. After opening the software, I first located the USB flash drive and then clicked the browse file option, but found that it was empty.
First try to repair the U disk problem, check the partition table for errors, if there are no errors, then search for the lost partition. This may take some time. If the problem is still not resolved, finally consider trying file recovery.
The interface for recovering files is very simple. Just click Start by default.
After completing the file scanning, the system will automatically organize various files, and you can immediately check the recovery you need. Whether the file has been successfully retrieved. Once you confirm that the files have been successfully recovered, you can copy them out through the software.
I have a lot of files to recover here. I checked and found that the files with the original directories and file names are all in isolated file directories of partition (1). I tried to copy them to the specified After opening the folder, I found that I could only recover some small files, and I needed to register before I could recover large files. I tried many versions, even if they had been solved, but it still didn't work. It was not thorough enough, so I had to change the software and try again.
The files recovered by the unregistered version are really pitiful. If you have purchased the registered version, you can try it. I feel that this file recovery should be the best.
2、winhex
winhex has not been used before, it is a bit professional, and I can only try some simple operations
After entering the main interface, click Tools and open the disk. Here you can select partition (logical drive) or disk (physical drive) drive), you can try one by one, select our U disk and click OK.
We can see the unpartitioned space above. If you can also see your original partition in addition to the unpartitioned space at this time, congratulations, you will have the opportunity to perfectly recover your data. sex.
Unfortunately, it is not displayed here, but you still need to try to recover. Click Tools-Disk Utility-Recover by File Type
Select the corresponding file type and set After specifying the recovery directory, click OK and wait for completion.
Unfortunately, the final recovery result was also unsatisfactory. The file names were replaced by numbers and the recovered data was incomplete.
3. EaseUS Data Recovery Wizard
This is the first time I have used this software, but the operation interface is relatively simple and easy to understand. Open it After using the software, you only need to select the U disk that needs to be restored, and then scan it
The software will automatically start to scan out the files
This software is very recoverable, with a total of only 16G It recovered a 17.6G file from a hard drive. Although the integrity of data recovery cannot be judged by its capacity, compared with the previous two software, this file recovery situation is better.
Summary: During this period, I not only tried the above three software, but also tried finaldata, recu, easyrecovery, etc. Some of them cannot recover the U disk with this error form, and some are different from the above three software. The content recovered by the software is not much different, but the functions are fewer. I think these three are the only ones that are relatively powerful.
diskgenius is an unregistered version, so the recovery is incomplete. However, judging from the scanned directory, this should be able to be restored perfectly. The minimum registered version is 288 yuan.
winhex is for professionals. Beginners should use it with caution. Accidental changes to the data may cause the data to be completely unrecoverable. However, this can be used to edit sectors more intuitively. Professionals can find some logic. If there is a mistake, if you change it, there is a chance that the whole disk can be restored perfectly.
EaseUS Data Recovery Wizard is the most fool-proof, but it also requires registration before it can be used. However, the X version is easier to find and the recovery integrity is better.
Data recovery is a relatively complicated matter. It is even more difficult to restore the original directory or all files. Moreover, most software requires registration or paid purchase. It is recommended to buy the genuine version or get it from a professional data recovery agency.
You also need to pay attention to the use of U disk. Never use U disk as the main file storage disk. U disk is the least safe thing. Whether it is an SSD or a mechanical hard disk, it is much more powerful than a U disk. One hundred times, the easy loss of U disk is also a disadvantage. The advantage of U disk is that it is easy to carry and compact. If there are important files on the U disk, you must make a backup. When storing important files, you must make multiple backups, no matter where they are stored. Okay, don't just store it in one place, you can't be lazy on this point.
