Defragment to Speedup Windows XP

Defragmenting remains an important task. Why? For one, power consumption and heat can be directly related to a fragmented hard drive. When the computer's operating system requests data, if a file is not contiguous, then extra seeking on the disk may be required. But a more important consideration is disk failure. Should a hard drive fail, the likelihood of successfully recovering data from the dead or damaged drive improves significantly if the data is contiguous rather than randomly scattered about the drive platters.
