Created attachment 32570 [details] skdump output Hi, skdump and palimpsest report weird (mostly useless) data for this disk why smartctl outputs correct data. I am attaching the output of skdump, skdump --save and smartctl -a (both running on an up2date F12 x86_64 box).
Created attachment 32571 [details] skdump --save output
Created attachment 32572 [details] smartctl -a output
