[Sugar-devel] Additional data for corrupted SoaS

[Sascha Silbe]

BTW, the SoaS Caroline gave me on SugarCamp (thanks!) is quite 
unreliable in one of my computers (it also confirms my suspection about 
the trouble she was having with my Assimilator software: hardware 
flakeyness). If you're using this run of sticks at the GPA, you can add 
it to the list of potential causes for stick failure.
As you're about to buy the next run: Do you have a "sample" model that 
you can try out in lots of different computers? Just run the following 
command in Linux, with only the to-be-tested USB stick plugged in:

dd if=/dev/disk/by-id/usb<press TAB once> of=/dev/null

e.g. for the stick mentioned above:

dd if=/dev/disk/by-id/usb-CHIPSBNK_USB_2.0_260917004B813900-0\:0 
of=/dev/null


If there's a problem, an error message will be printed as part of the 
output:

sascha.silbe at twin:~$ dd 
if=/dev/disk/by-id/usb-CHIPSBNK_USB_2.0_260917004B813900-0\:0 
of=/dev/null
dd: reading `/dev/disk/by-id/usb-CHIPSBNK_USB_2.0_260917004B813900-0:0':

If it's sucessfull, the whole stick will have been read:

sascha.silbe at elaine:~$ dd 
if=/dev/disk/by-id/usb-CHIPSBNK_USB_2.0_260917004B813900-0\:0
