Data scrubbing. Data scrubbing is an error correction technique that uses a background task to periodically inspect main memory or storage for errors, then correct detected errors using redundant data in the form of different checksums or copies of data. Data scrubbing reduces the likelihood that single correctable errors will accumulate, leading to reduced risks of uncorrectable errors. Data integrity is a high-priority concern in writing, reading, storage, transmission, or processing of the computer data in computer operating systems and in computer storage and data transmission systems.
Second opinion The above is not really accurate, color blindness can be caused by cataracts, Both my parents were unable to tell the difference between colors of things for many years after developing cataracts. Only the various shades of beige (Mother) or grey (Father) were apparent. Luckily this can now be cured by surgery. So the answer to this question must be :- Yes you can go color blind but there are possibilities for this to be reversed. 1 person found this useful.
Ninety-nine percent of people with color blindness have difficulty distinguishing between red and green. The absence of one pigment will cause red-green colorblindness. The absence of two pigments will make it difficult to distinguish between blue and yellow as well as green and red. Achromatopsia, the rarest kind of colorblindness, involves the absence of all three pigments. People suffering from this form of color blindness can only see in black, white and gray.
