The results of this operation are nothing but harmful to the overall performance of the hard disk and at the same time the computer as the system will need more time to find the required files on the disk. However, you should know that if the entire file does not fit the gap it'll fill that empty sector and move to the next free space it finds to place the rest of the data. When another file needs to be written, the disk will place it in the fastest detected gap it finds. With NTFS, this theory no longer stands and defragmentation is 100% safe and recommended by many.įragmentation of the files occurs when deleted files leave empty spaces in between stored data on the disk. And this can be done by constantly defragmenting stored files in order to obtain faster read/write times.ĭefragmentation used to be a tricky back in the days of FAT file system as if a power shortage occurred during the process you could have fried your disk. That is one reason why you should take better care of it in order to squeeze maximum performance. Being the only computer component with moving parts, the hard disk is also the slowest hardware piece of your PC.
