I don't know of any linux tools that support this. The problem is that the detailed information about which sectors are in trouble, and the kind of trouble, is vendor-specific. And as far as I know, none of the vendors document this, although they make use of it in vendor-specific tools. Bruce On Sat, 2 Sep 2006, Serguei Miridonov wrote: > Hello, > > Please, see subject.
