something curious Media Writer -- Gparted

[Joerg Lechner]

Hi,
could not delete a full F24 installation on an 32GB USB flash drive with Gparted, therefore I used a workaround with building an iso with the Fedora Media Writer on this flash drive. Afterwards I deleted this iso with Gparted. Delete was successful, but Gparted showed now a flash drive with 117GB and it was not possible to get a working partition. Using the restore to factory settings with Media Writer repaired the flash drive again to 32GB. Normally Gparted -as I have seen so far- works correctly. Is there an error in setting the "correct end" of the flash drive (in my case 32GB) in the production of an Fedora iso?
Kind regards
