[QUOTE="chas_m, post: 1637097"] You can: 1. (following a complete clone backup, to an external drive) Boot from your clone and erase the hard drive, selecting to erase with zeros for a single pass. This will lock out bad sectors, and won't take days like the other options. Then clone back from your clone backup. This also does what people use to call "defragging." 2. Buy a replacement hard drive. Hard drives are stupid cheap these days, and a drive with problems is never going to get better, just worse. (shakes fist at cwa for typing faster than me) [/QUOTE]
