In this article, the editor introduces in detail "how to mount the FAT32 U disk under the Linux system". The content is detailed, the steps are clear, and the details are handled properly. I hope that this article "how to mount the FAT32 U disk under the Linux system" can help you solve your doubts.

The steps for linux to mount a U disk are as follows

1: insert the USB disk into the usb port and check if it is plugged in.

2: use the fdisk command to check partition and usb device information

[root@wgods ~] # fdisk-l

Disk / dev/sda: 1000.2 gb, 1000204886016 bytes

255 heads, 63 sectors/track, 121601 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device boot start end blocks id system

/ dev/sda1 * 1 13 104391 83 linux

/ dev/sda2 14 121601 976655610 8e linux lvm

Disk / dev/sdb: 4012 mb, 4012900352 bytes

223 heads, 55 sectors/track, 639 cylinders

Units = cylinders of 12265 * 512 = 6279680 bytes

Device boot start end blocks id system

/ dev/sdb1 * 56 640 3580928 c w95 fat32 (lba)

Partition 1 has different physical/logical beginnings (non-linux):

Phys= (42,17,40) logical= (55,23,1)

Partition 1 has different physical/logical endings:

Phys= (487,222,55) logical= (639,6,31)

From the above information, we can see that the usb device is in fat32 format and is identified as / dev/sdb1

[root@wgods ~] # fdisk-l | grep fat32

/ dev/sdb1 * 56 640 3580928 c w95 fat32 (lba)

3: create a usb directory under the mnt directory

[root@wgods ~] # cd / mnt/

[root@wgods mnt] # mkdir usb

4: Mount the u disk

[root@wgods mnt] # mount-t vfat / dev/sdb1 / mnt/usb

After the mount is successful, we can see the relevant content under / mount/usb.

5: uninstall the u disk

When executing the umount command to uninstall the u disk, the error "device is busy" is reported as follows, and the parameter l can be used to solve the problem. Of course, you can also solve the problem with the fuser command. As shown below

[root@wgods ~] # umount / mnt/usb

Umount: / mnt/usb: device is busy

Umount: / mnt/usb: device is busy

[root@wgods] # umount-f / mnt/usb

Umount2: device or resource busy

Umount: / mnt/usb: device is busy

Umount2: device or resource busy

Umount: / mnt/usb: device is busy

[root@wgods ~] # umount-l / mnt/usb

Problem solving

[root@wgods usb] # umount / mnt/usb

Umount: / mnt/usb: device is busy

Umount: / mnt/usb: device is busy

[root@wgods usb] # fuser-m / mnt/usb

/ mnt/usb: 21123c 21158c 21180c 21182c 21223c

[root@wgods usb] # ps-auxw | grep 21123

Root 21223.. c.. Bash

[etl@wgods ~] $umount / mnt/usb

Umount: / mnt/usb is not in the fstab (and you are not root)

[etl@wgods ~] $su-root

Password:

[root@wgods ~] # umount / mnt/usb

6: delete the usb directory

[root@wgods ~] # umount-l / mnt/usb

[root@wgods ~] # rm-rf / mnt/usb

Note: sometimes when mounting, the Chinese file name and directory name will appear garbled, to avoid this situation, you can specify the character set, the command is as follows

[root@wgods] # mount-t vfat-o iocharset=utf8,codepage=uft8 / dev/sdb1 / mnt/usb

[root@wgods] # mount-t vfat-o iocharset=cp936,codepage=936 / dev/sdb1 / mnt/usb

Note: cp936 refers to simplified Chinese and cp950 refers to traditional Chinese.
