(parted)

=======================================

parted reports what /dev/sda4 partition has size of 7711272591s
but this is not true, partition size is 7711272590s:

7814037168 - 2014 -  2097152 - 100665344 - 34 - 34 == 7711272590

P.S.

sorry, I can't find bugzilla for parted and can't check
what this bug for parted was previously reported and fixed.
