[Bug 1302762] Re: gpartedbin crashed with SIGSEGV in _int_free()

[cliff tinker]

the fault appears to be caused by my hitachi external 2tb drive.as soon as i powered off the drive gparted is working normally again.
if this drive is running when the system boots it reports bad secor size (i have tried formating this drive in different filesystem's but it seems not to cure the problem. grub also reports this whenever i run update-grub :
