[Bug 1589028] [NEW] Improper blocksize set by usb-creator, leads to problems during formatting

[Severus Tux]

Public bug reported:

When ever I create a bootable USB using usb-creator , and when I try to
format it after my work is done, I get this error

“The Driver descriptor says physical block size is 2048 bytes, but Linux
says it is 512” in Gparted. (screen shot in the attachment)

Furthermore , The USB is divided into strange partitions (image
attached). and shows the 16GB partition as 60GB partition.

I presume that this is because of setting the blocksize to 1000000 by
this tool : as in the source code here : https://bazaar.launchpad.net
