It affects me, too. And here are some details from me...
I am running Ubuntu 16.04.1 LTS, 64-bit. For some time I have been using Startup Disc Creator to create Lubuntu 32-bit install media (on USB flash drives). However, today (8th September 2016), when I was attempting to create a Lubuntu 16.04.1 LTS desktop 32-bit install USB flash drive using Startup Disc Creator (0.3.2), it would write the iso to the flash drive OK. Except for one thing. The flash drive is not being recognised. To quote GPartEd, "Unable to detect file system!". Bit more: Whilst the resulting install media can install Lubuntu OK, you just can't look at it with a File Manager or GPartEd. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1622313 Title: gparted does not recognize the iso9660 file system in cloned Ubuntu USB boot drives To manage notifications about this bug go to: https://bugs.launchpad.net/gparted/+bug/1622313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
