Number 1, make sure that you have turned on automatic sector remapping on that disk. How you do that can vary by disk manufacturer, but see the FAQ entry on bad block remapping. Number 2 is to get a new disk cable; cable problems are at least as common as disk failures in my experience, and it's *really* annoying to replace a disk and find that the problem wasn't the disk in the first place. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/
