Hi,
that's what I see with Gparted (screenshot), trying several menues of
Gparted I can draw it back to 29,5GB, but after new iso with Fedora
Media Writer this impossible size over 100GB is shown again. It's a Hama
flash medium 32GB. Is this caused by Media Writer? Or is something
hidden (i.e chip originally planned for 128GB but because of bad quality
only sold for 32GB)?
Kind regards

Betreff: something curious Media Writer -- Gparted
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
Hello Joerg,
The reason is the partition table of the Fedora ISO image that was written
on your flash drive - it includes the information that the blocks on your
flash drive are 2048 bytes large but the actual blocks of the flash drive
are in fact only 512 bytes. Therefore GParted assume your drive is 4 times
as large as it really is.
This happens with all flash drives, except maybe those with different
block sizes but those seem to be rare.
That's the reason I implemented the "drive restore" option into Fedora
Media Writer - restoring this state manually, especially using GParted, is
tedious.
Hopefully this answered to your concerns and if not, do not hesitate to
contact me, even directly.
Martin
