What to do if Linux cannot read the USB disk

Method: 1. Use "modprobe [module]" to add the "usb-storage scsi_mod sd_mod" module and create a new directory in the mnt directory; 2. Use "mount -t vfat /dev/sda* /mnt /New directory name" to create a mount point.

What to do if Linux cannot read the USB disk

1. Add the specified module

Execute the following command:

#lsmod

Viewusb-storage scsi_mod sd_mod Whether the module has been added, if the above module is not found, execute

#modprobe [module]

to add it.

modprobe is used to automatically handle loadable modules.

1) Syntax

modprobe [-acdlrtvV][--help][模块文件][符号名称 = 符号值]

2) Supplement

modprobe can load specified individual modules, or load a group of dependent modules.

Both insmod and modprobe load kernel modules. The difference is that modprobe can handle the dependency problem of module loading.

Then create a USB directory in the mnt directory.

If only one U disk is currently inserted and your hard disk is not a scsi hard disk interface, then its hardware name is: sda1.

2. Establish a mount point

For example, /mnt/usb, execute the following command

#mount /dev/sda /mnt/usb

Some systems need to point out the mount point file type, you can execute the following command:

#mount -t vfat /dev/sda /mnt/usb

Finally use

umount /mnt/u。

when uninstalling. Recommended learning: Linux video tutorial
