fdisk says the disk is 250GB and you have a 240GB sda2 partition.

sda2 is a pv (physical volume) of around 230GB, as you can see here.

230/240/250 is all the same, as there are some confusing definitions
of how big a gigabyte is.
So, what is happening is that:
- either the disk is 250GB and not 350GB (try "hdparm /dev/sda",
"hdparm -i /dev/sda")
- or the disk is 350GB but it is partitioned as if it were 250GB; this can happen
if you copy an entire 250GB disk to a bigger one ("dd if=dev/sda of=/dev/sdb"),
because you copy the partition table values which specify how big the disk is.
Let's see what hdparm thinks.
Model number + google search will tell us how big your disk really is.
Best regards.
