boot - My USB wont mount - Ask Ubuntu


when plug usb computer starts flash undetectable computer. on windows says unrecognized. wont show on ubuntu. have tried formatting cant find on there or anywhere else, have tried fixing on windows. have checked devices , tried update drivers on root hub. have tried plugging 2 different usb ports on both computer. sandisk 8gb usb.

help

let me give 15 seconds of explanation let's dive in. physical disks noted alphabet letter , partitions noted number. vanilla system sdax (x being number) , next drive (that usb) become sdbx.

with drive disconnected, open shell , run following command:

lsblk 

you should see this:

sda                          8:0    0    35g  0 disk ├─sda1                       8:1    0   243m  0 part /boot ├─sda2                       8:2    0     1k  0 part └─sda5                       8:5    0  34.8g  0 part   ├─mint--vg-root (dm-0)   252:0    0  33.2g  0 lvm  /   └─mint--vg-swap_1 (dm-1) 252:1    0   1.5g  0 lvm  [swap] sr0                         11:0    1  1024m  0 rom 

now plug drive in again , run same command above. did find flash drive? if answer no, have bad drive. if answer yes, let's mount it.

for explanation sake, i'm going use sdb1. replace sdbx, sdcx, etc..., whichever correct on system.

cd mkdir usbflash mount /dev/sdb1 usbflash 

from point should see flash drive listed usbflash in file manager gui, or cd usbflash , work inside of command line.

if fixed up, can see drive following command:

mount 

when you're done drive, can unmount appending path found command above:

umount /path-here
