ISO disk image not read by disc Creator

[FLoyd Roberts]

Trying to create a bootable USB stick (actually this is being done to recover an interupted (power line failure) upgrade to 12.04) I am able to boot my system with an alternate hard drive, and the drive is seen and the files seem present, however I need to install/reinstall a new version of 12.04. Thus the need for a bootable USB (cd drive does not work) - USB creator will find the USB stick fine, however the downloaded ISO is apparently never loaded. This might be similar to

https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/500526

but I am not savvy enough to know. I have tried running disk creator from the command line but get the following

floyd@DPR1500:~$ usb-creator-gtk -i ubuntu-12.04-desktop-i386.iso
isoinfo: Short read on old image

Suggestion is that the iso is bad so I will download another, but any guidance would be appriciated -- I am still basically just trying to recover the system from a poorly timed power failure.

Status changed to 'Confirmed' because the bug affects multiple users.

I had this problem with an image from the official torrent--so I know the hash is good. This was with the Quantal Server I386 image.

I have the same problem. 1. A new image is not loaded to startup disk creator when selected. 2. If the image file is corrupt, it is ignored with no warning 3. Startup disk creator quits unexpectedly when done creating the disk, sparking a system error message (it was launched from command line when this happened)
