Hi rpetrenko,
Are you sure that /dev/sda exists. You need to make sure that your system is puting the usb drive as the sda1 device. The best way to check this is by looking through the output of dmesg: "dmesg | less"

do a ls in /dev. What sd devices show up? If suse uses udev or devfs then the sd device that the usb drive belongs to should be the only one that shows up. If a whole bunch of devices are showing up then it is probably not using devfs or udev and just check dmesg for which one it is.

check it out graphically, too!

Go to YAST --> System --> Partitions

click on the correct partition and edit it and mount it.

Just my guess
