After you insert a USB device in the USB slot, the Linux system automatically detects and mounts the device. If you cannot view files on the device, perform this procedure.
Note
Not all hardware platforms can use the USB device for additional file storage. Some platforms use the USB as part of the system operation and must never be removed. For more information, see your hardware documentation.
enable
ls /usb/
usb-stop
dos-chkdsk /usb
Run the dos-chkdsk /usb repair command, if at the end of the dos-chkdsk /usb command output you see:
1) Correct
2) Don‘t correct
dos-format /usb
Caution
If you format the device, you erase all data on the device.
Check the file system:
Switch:1>enable Switch:1#ls /usb/ Listing Directory /usb/: drwxr-xr-x 4 0 0 4096 Jan 1 1970 ./ drwxrwxr-x 22 0 0 0 Sep 9 20:22 ../ drwxr-xr-x 2 0 0 4096 Mar 17 16:03 Photos-of-Flash- drwxr-xr-x 2 0 0 4096 Jun 13 20:56 intflash/
Check the device for errors:
