Thanks for the report. > When i look into the documentation of gpt partitions it seems to be right > what windows has done. Why? Please provide more information, e.g., the output of this: (assuming your disk is /dev/sda) # parted -s /dev/sda u s print free That will tell us the size in sectors of your disk. Then tell us the actual values from your primary table by running this: (again, assuming /dev/sda) # od -w8 -Ad --skip=$((512+32)) -N24 -td8 /dev/sda _______________________________________________ bug-parted mailing list bug-parted@gnu.org http://lists.gnu.org/mailman/listinfo/bug-parted
