http://ubuntuforums.org – The flashdrive was corrupted or something. I couldnt access it at all. So, I decided to reformat it. I used gparted and tried to format it to fat16 without any success. Then tried fat32 without success. NTFS doesnt work either. So, I format it to ext4 file format. Now the permissions for flash disk is root. I cant chown. What is the best way to format the flash drive from the terminal? fdisk -l Code: Disk /dev/sdb: 8011 MB, 8011120640 bytes 255 heads, 63 sectors/track, 973 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 5 (Hardware)
