http://www.linuxquestions.org – I am using an embed linux application and trying to mount a USB device. The USB worked fine in windows. I then put it on my Linux box formatted (I hope correctly) And then tried to do the following to mount it Code: Disk /dev/sda: 4040 MB, 4040748544 bytes 255 heads, 63 sectors/track, 491 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes   Device Boot      Start        End      Blocks  Id System /dev/sda1              (HowTos)
