On mine, the U3 doesn't show in fdisk -l, but the storage does as Fat32. U3 is a dos executable, that's the part I was letting the OP know doesn't work in linux. If they want to play around they probably can try wine, but the fat partition is useable on linux.
It's FAT32 SanDisk. I did try to open it through wine but failed anyways.
The output from fdisk -l is:
Disk devsdb: 16.0GB, 16008609792 bytes
255 heads, 63 sectors/track, 1946 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optional): 512 bytes / 512 bytes
Disk identifier: 0x00000000
W95 FAT32 (LBA)
Sorry i can't just copy and paste because it's my laptop that i am having trouble with and internet on it isn't working either ha.
Sometimes devices don't automount, in which case you should try to manually mount it. First, you must know what device we are dealing with and what filesystem it is formatted with. Most flash drives are FAT16 or FAT32 and most external hard disks are NTFS.
sudo fdisk -l
Find your device in the list, it is probably something like /dev/sdb1.
Create the Mount Point
Now we need to create a mount point for the device, let's say we want to call it "external". You can call it whatever you want, just please don't use spaces in the name or it gets a little more complicated - use an underscore to separate words (like "my_external"). Create the mount point:
sudo mkdir /media/external
Mount the Drive
We can now mount the drive. Let's say the device is /dev/sdb1, the filesystem is FAT16 or FAT32 (like it is for most USB flash drives), and we want to mount it at /media/external (having already created the mount point):
sudo mount -t vfat /dev/sdb1 /media/external -o uid=1000,gid=1000,utf8,dmask=027,fmask=137
The options following the "-o" allow your user to have ownership of the drive, and the masks allow for extra security for file system permissions. If you don't use those extra options you may not be able to read and write the drive with your regular username.
Otherwise if the device is formatted with NTFS, run:
sudo mount -t ntfs-3g /dev/sdb1 /media/external
You must have the ntfs-3g driver installed. See MountingWindowsPartitions for more information.
Unmounting the Drive
When you are finished with the device, don't forget to unmount the drive before disconnecting it. Assuming /dev/sdb1 mounted at /media/external, you can either unmount using the device or the mount point:
sudo umount /dev/sdb1
sudo umount /media/external
You cannot unmount from the desktop by right clicking the icon if the drive was manually mounted.
There is a program called pmount available in the repositories which allows unprivileged users to mount drives as if they were using sudo, even without an entry in /etc/fstab. This is perfect for computers that have users without RootSudo access, like public terminals or thin clients.
pmount can be used with the same syntax as mount (but without sudo), or quite simply as follows:
pmount <device> [ label ]
pmount /dev/sdb1 flash_drive
This will mount the device /dev/sdb1 at /media/flash_drive
If you leave off the label option, it will mount by default at /media/device
To unmount the device, use pumount, like so:
For more help, you can see the man pages for pmount and pumount.
Before disconnecting devices, you must unmount them first. This is similar to "Safely Remove" in Windows in that the device won't unmount until data is finished being written to the device, or until other programs are finished using it. This applies to all types of storage devices, including flash drives, flash cards, external hard drives, ipods and other media players, and even remote storage like Samba or NFS shares.
Failure to unmount before disconnecting the device can result in loss of data and/or a corrupted file system. There are no exceptions to this rule. Be safe - unmount your drives before disconnecting them! "
when i got to this bit sudo mount -t vfat /dev/sdb1 /media/external -o uid=1000,gid=1000,utf8,dmask=027,fmask=137
the following error came up: wrong fs type, bad option. bad superlock on /dev/sdb1 missing codepage or helper program, or other error in some cases usefil info is found syslog - try dmesg | tail or so.
