I just bought a new pendrive of 8gb storage. It is detected in windows but not in the Ubuntu,but the light in the pendrive still keeps flashing,so I think the pendrive is ok.


Not all types of partitions are automatically mounted by Ubuntu. But that doesn't mean the USB drive is not detected.

Run the following command to see all mountpoints.


This will show something like

/dev/mapper/ubuntu-root on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
none on /run/user type tmpfs (rw,noexec,nosuid,nodev,size=104857600,mode=0755)
/dev/sda1 on /boot type ext2 (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
gvfsd-fuse on /run/user/aditya/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=aditya)
/dev/sdb1 on /media/aditya/Aditya type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks2)

To see device of only certain format, use

mount -l -t<type>

for example, to show only fat partitioned drives, run

mount -l -tvfat

In most cases, the last one would be the externally mounted drive. Then run the following command to mount the drive.

udisks --mount /partition

For example

udisks --mount /dev/sdb1

To unmount

udisks --unmount /dev/sdb1

Once mounted, you should see the drive(partition) in both dash and nautilus(or your favorite file manager)


Maybe it is an ExFat partition, so you will need to install support for it. Just do sudo apt-get install exfat-fuse exfat-utils and reinsert your flash drive. Another possibility is that your stick is NTFS formated and it was not removed safely. Just insert it into a win computer, do a scan disk ,remove it cleanly and try angain in Ubuntu. I hope it helps.
