On the other side, we have the end of life, where the failure rate steadily increases. The rise in the rate of failure is not as sharp as failure decreases in the early life stage, but it is a fairly steep rise. This is the time when your drive fails for seemingly no reason. It is literally when your drive is “wearing out”.
While it seems like this is some mystical, hidden reason that you’ll never be able to understand, or perhaps it’s something that is completely out of your control, that’s not necessarily true. Whenever a sector of a disk is damaged, that sector is labeled as a ‘bad sector’ and is ‘mapped out’. This keeps these bad sectors from affecting the drive’s operation, and allows you to continue using the drive as normal. This process is completed by the computer and is done without the user’s awareness. As more and more sectors are mapped as bad, less and less of the disk can be used. Eventually, enough sectors are damaged that normal use cannot continue. It’s easy to see how, over time, it’s inevitable for the disk to ‘wear out’.
Fortunately, there are ways to extend the life of your hard drive, and there are a variety of warning signs that will tell you that your hard drive is on the up-slope of the Bathtub Curve. If you think your hard drive is on its last legs, be sure to backup your data. If you’ve waited too long, contact us today to get a quote on recovering your lost data.
