Disk wear is usually greater on a non-defragmented drive than on a drive that is defragmented regularly. According to Lance Jensen, Executive Software Technical Support Representative, “Reading a file from the disk requires at least one disk access for each fragment.

But if you do not defragment, then just reading those fragmented files will require the same amount of disk access. In fact, every time you read a fragmented file, the computer will be doing as much disk acc
