I can not mount USB devices

[allegro-vivo]

Until yesterday it was always fine, but now I've problem with mounting usb keys and sd cards.

I've connected an external hard drive, a 8 GB sd card and a 32 GB sd card via usb (with usb adapters)

• Thunar is not showing any usb device. (see 1st attached image)
• GParted detects the external hard drive and the 8 GB sd card. (see 2nd attached image)
• Windows XP on VirtualBox detects and manages the 8 GB sd card, I could read and writes the files on it. (see 3rd attached image)

On Terminal I've typed:

• sudo fdisk -l and this was the output:

what can I do?

To mount  a vfat partition, put into /etc/fstab the following:  /dev/sdd1  /media/8gbstorage  vfat  user,fmask=0111,dmask=0000  0  0
where you replace sdd1 by the corresponding partition searches as shown the partition to be, and 8gbstorage by whatever name you want it called.  From your data (your images did not show)  /dev/sdd1 should work for the 8GB volume.

To mount a ntfs partition, put into /etc/fstab the following:   /dev/sdd1  /media/windows  ntfs-3g  defaults    0    0
where you replace sdd1 by the corresponding partition searches as shown the partition to be, and windows by whatever name you want it called.
