Comment 67 for bug 438136

I'm not sure of this to be a bug. I installed in my home computer with three HD with no problem. At work I installed again and Ubuntu gave and error in a HD I use for data collection. I know that this HD had bad sectors (an error that have been shown years ago), and I changed it for a clone (Western Digital, 320GB bought at the same time, same model, consecutive identification number) and no error was found. I bought a new computer with a new Western Digital 500GB Caviar Green (I opened the box) and it was impossible to install Ubuntu because of the bad sectors found (impossible to boot). I changed the HD for a clone (same model etc...) and no error was found and Ubuntu was installed in minutes. Two identical couples of HD in the same computers, with no other variation are treated in different way for this bug. I was thinking in this situation for a week and really I do not know what to do. In fact I changed these two HD, but I am not sure if it is a bug or not
