U disk must have been indispensable in everyone's daily life and work, it makes our documents maintenance and transfer more convenient and easy. However, with frequent use, file system errors, bad blocks, and bad sectors may affect normal use. For Windows users, there is a dedicated graphical tool to fix such USB disk problems, while Linux users are relatively troublesome.

Use fsck to remove bad blocks from USB drives

The easiest way to repair flash drives or other types of drives in Linux is to use the fsck tool, which is a powerful tool for removing bad blocks, solving "unreadable" problems, and fixing most file system problems. Before that, however, you need to use the lsblk command to determine the U disk, which lists all the disks connected to the current Linux system.

To delete bad file blocks, execute the fsck command on a specific partition (such as / dev/sdc1) or an entire disk (such as / dev/sdc), and once done, you will get a healthy Linux partition.

Clear USB drive

When it appears that the U drive is completely unreadable and the data in it is worthless, the best way to fix it is to use the dd command to completely zero the U drive.

Similarly, use the lsblk command to find the U disk, and then use a command similar to the following to clear the zero:

Sudo dd if=/dev/zero of=/dev/sdb

After the zeroing operation is completed, you need to repartition the disk with fdisk or other tools, and then select the following command to format it for normal use:

FAT32

Sudo mkfs.msdos-f 32 / dev/sdb1

EXT4

Sudo mkfs.ext4-f / dev/sdb1

NTFS
