U disk open prompt to format, but cannot format

Workaround One (recommended):

1. Click Start, click Run, type cmd and enter to open the Command Prompt window;

2, enter the following command in this window: for example, the USB drive is the F drive (if your USB drive is G-drive, the following F is changed to g): Chkdsk h:/f Enter (that is, press the ENTER key on the keyboard), after a while, if not, please try Method two

Workaround Two:

1, first use the FAT file format to format the U disk (remember: Be sure to remember the previous file system!)

2. Then use Easyrecovery Pro software

3. After installing the software, go to Data Recovery format recovery (select your USB flash drive's previous file system in the previous file system)

4, then the next step, the software began to scan, after the scan, the data are copied out, and then the principle: Because the advanced format is only rewrite partition table, not really delete files, so we can use the data recovery software to find the previous file back Note: You must pay attention to, after you format finished, Do not write to the U disk, or the file may not be found, or garbled!

The way I use it myself:

1. Open the Diskgenius software in WinPE and select "Search Partition", search scope Select "Entire hard disk", search mode Select "Automatic".

2. Then the software will start to search the partition automatically, after a period of time, all the partitions on the hard disk will be displayed in the form of a list

3. Select the partition you want to restore, then click on "hard drive → save partition Table". Once saved, right click on "Extended Partition" on the left and select "Reload Current Partition". Once selected, the deleted partition is restored. (I did not manipulate the red font)

！！！ U disk in the use of the U disk can not read and write in the process of pulling out the U disk, although the U disk support hot plug function, but the long-term operation may result in the U disk data loss, will also affect the life of U disk
