I tried sd_format and the following is the result :

I heard the click you spoke of in the precedent article. The drive
worked ten seconds or so and stopped. Does this mean the formatting is
terminated normally? The format field is incremented, indeed ...

I have some "Fuji" disks. But the first disk I had this problem with is
Iomega's one. I now have one Iomega, one Fuji and two Sony unusable. I
don't dare try the rest for fear ... I would say it is contagious.

I downloaded ppa-1.41. It works fine without giving kernel panics any
more. Thank you for your nice work.
