Disk /dev/sda: 351905 cylinders, 64 heads, 32 sectors/track Warning: extended partition does not start at a cylinder boundary. DOS and Linux will interpret the contents differently. Warning: The first partition looks like it was made for C/H/S=*/255/63 (instead of 351905/64/32). For this listing I'll assume that geometry. Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
