The process of disk optimization and Defragmentation in Mac OS collectively represent an issue and a matter of debate over repairing the disk permissions. According to Apple’s advice, there exist two scenarios in which you may need defragmentation of your drive. These two conditions determine the extent of defragmentation needed by your iMac PC. First you may have many numbers of large files and the second one is that your disk may low on disk space i.e. it may be more than 90% full of the total hard drive space. If these are your only concerns, then there are some remedies for you which may help you out to get out of trouble.
In the case you have myriad large files then you can easily create a back up of your important data. Basically everything except the files of operating system, then you have to re-install the Mac OS and then restore files from your backup. It seems somewhat tedious but actually this would result in a faster access to your large files. If you don’t like to do all this, you can use simple utilities like Super Duper! To make a exact clone of your startup drive, then you have to simply format the hard drive using the Apple’s Disk Utility that is located in Applications or Utilities and then you can copy your files back.
Steps to follow up while defragmenting a hard disk drive on iMac Pc:
Open Disc Utility program, located in “Utilities” folder of “Applications” directory. Highlight hard drive from list and have program repair. This is quite an easy and common way to correct some of common errors which may slow down your hard disk drive.
Now look for the program to defragment your computer hard disk drive.
