More testing of usb-creator-gtk in the 32-bit version of Lubuntu Raring


Hi Jonathan,

This is a long mail because I have included a lot of details. But I
start with a summary.

Best regards
Nio

*Summary and comments*

Using usb-creator-gtk without mounting the partition on the target USB
drive has started to work for me.

This worked when writing to a slow Sandisk Cruzer 4 GB USB2 flash drive
with normal termination, but caused a segmentation fault, when writing
to an IDE disk connected via a no-brand-name adapter called

"USB2.0 to IDE & SATA cable"

However, a persistent live USB drive was created. This is different from
my results a couple of days ago, when segmentation fault in this 32-bit
Lubuntu 13.04 caused a dead USB drive.

It used to work only when the partition on the target USB drive was mounted.

I tried once more to make the USB HDD work as persistent live drive.
This time there was no segmentation fault, although the partition on
that drive was not mounted.

So flaky, yes, but things are improving.

I don't know, if I am doing things more consistently, or if a bug-fix
has trickled down :-)
