Many people that got confronted with it said bluntly that the problem simply has no solution, otherwise it would contradict common sense, information theory, etc. But surprisingly, it does have a solution. For X% strictly bigger than 50% the solution is known as the MJRTY algorithm, discovered a while back by R.S. Boyer and J.S. Moore (also called the Majority Vote...http://blogs.msdn.com/adioltean/archive/2007/11/26/puzzle-solution-xen-voting-algorithm.as...

Not that I trust SMART a lot, but I wanted to see what's there. So that's how I discovered my main drive has a bunch of reallocated sectors. Ouch! What is a reallocated sector Whenever a sector becomes "bad" for some reason, modern harddisks are "remapping" this sector to some other location of the disk. That's why you almost never see "bad clusters" on a modern harddisk...http://blogs.msdn.com/adioltean/archive/2007/11/13/is-my-harddisk-almost-dead.aspx What causes Harddisk failures- November 13, 2007 A fascinating article in ACM Queue examines the various ways in which a harddisk can fail. Here is an example - the fault tree for reading failures.http://blogs.msdn.com/adioltean/archive/2007/11/12/what-causes-harddisk-failures.aspx |
