i doesn't work.

When I try #mount /mnt/pen i get:
modprobe: cannot fin module block-major-8

and /mnt/pen doesn't get mounted. I also tried #mount -t auto /dev/sda1 /mnt/pen and got the same result.

I've tried loading kernel modules: sg (for SCSI generic control) and some usb related, like usb-ohci and usb-uhci (which purpose, beeing a clueless linux newbie with a poor understanding of english, don't really grasp). usb-ohci fails to load, while in my laptop, it gets loaded automatically at boot time.

I can get a full refund for this pen drive, should i take it back to the store or should I wait and continue trying?
