I did it on Ubuntu Server ISO using usb-creator-gtk, using my general USB flash drive and its size is 8GB, and it did the same thing so I deleted the culprit partition using Gparted, and no errors like that is displayed and it removed the partition completely, then, I was able to create the FAT32 partition. From now on, I have to use Rufus, the perfect tool on Windows.
usb-creator-gtk tried to set the flash drive's partition into ISO 9660, which means it is not recognized by some systems, and is read only. I removed the partition completely that is ISO 9660, then I formatted it on FAT32 (partition size is 7.6GB after ISO 9660 removal). So I suggest everyone who wants to create a Ubuntu flash drive must use Rufus, or Universal USB Creator, until this bug is fixed to avoid damage to your USB flash drive's partition. Some users (like me) have this bug but they are able to remove the culprit, iso9660 partition and recreating the FAT32, useful, read and write partition. Others have this bug but they are not be able to remove the culprit, iso9660 partition and shows that error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589028 Title: Improper blocksize set by usb-creator, leads to problems during formatting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/parted/+bug/1589028/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
