Startup Disk Creator says "The device is not large enough o hold this image" even though it displays that my device has 3.7 gb free.

[Kostas Kapatos]

This happened because I had a dvd movie in my drive. When I opened the usb creator it took as source the movie. I did select the iso with ubuntu from "Other..." but for some reason it still says that my usb stick doesn't have enough space. I removed the dvd from the drive and re opened the usb creator but still the same.

I reproduced this in 12.10 using usb-creator 0.2.40ubuntu1. I am trying to burn the 12.10 DVD image onto a 1GB flash drive with 978MB free. I get the same, "The device is not large enough to hold this image" error.

This seems to still exist in Bionic.

Package: usb-creator-gtk 0.3.5ubuntu18.04.2

Steps I performed:

1. Download 20.04 Server ISO (into Downloads dir).

2. Insert 16 GB USB stick.

3. Launch Startup Disk Creator.
3a. "Source disc image" has the 20.04 ISO already selected.
3b. "Disk to use" has the USB stick already selected, shown with 14.9 GB capacity.
3c. Under the list of disks is the message "The device is not large enough to hold this image."
3d. "Make Startup Disk" button is disabled.

Observation/characterization:

In my case, the disk list includes a second device (maybe a mount of a directory on the USB stick?) of size 22.0 kB. If I select that second device, and then select the USB stick again, the "not large enough" message disappears and the "Make Startup Disk" button is enabled. So it seems that whatever evaluation is performed when a new destination is selected must not be getting performed when the destination is set to a default at application startup.

It may be possible to work around the issue by removing and re-inserting the USB stick. However, I can't test that because, in my case, removing the stick causes the other item in my list of disks to become selected, and I have to manually re-select the USB stick afterwards. Hence, I can't see what happens if you re-insert the stick as the only available device.

Minor correction: My guess about the origin of the second device in my "Disk to use" list was wrong--it can't be a mount on the USB stick, as it remains in the list when the USB stick is removed. But its origin is tangential anyway--the point is only that, in my case, I was able to work around the issue specifically because there was some other device in the list.
