Comment 16 for bug 690606

I found out something interesting by accident.

If I create a natty boot disk with usb-creator-gtk and choose the option to store documents and settings on the disk (tested with 1GB) the crc32c error occurs, but if I turn it off and select to discard any changes on shutdown, it works!

So then I had a closer look and noticed the HDD LED is lit up when the error occurs. I took out the harddrive and tried again and the HDD LED was still lit. I figure it shows the USB read/write activity, too, since there was no other drive the laptop could possibly read from or write on.

This was tested on my Thinkpad R51. "lsmod" made with the same natty live CD as the one of my X61 before:
