Running fsck from Single User Mode 3:34-4:15 There's one more disk optimization utility we should look at it. But to run it, we need to restart the system in single user mode, which is the Mac OS command line maintenance utility. So, let's restart the system. We've booted into single user mode. This is a command line mode that can be used to perform various system maintenance tasks, including disk verification. To do this, we need to run the 'fsck' command and we're going to run it with the -fy options. These specify the utility to clean the file system, and also to automatically fix any errors it encounters. Press Enter and utility will run. When we see that the file system appears to be okay, we know the utility is finished and we can go ahead and reboot the system. Summary 4:16-4:26 That's it for this demonstration. In this demo, we looked at how you can optimize disks on a Mac OS system. We looked at identifying file and folder size. We looked at the Disk Utility. We also looked at running fsck from single user mode. Optimizing your hard disk drive can improve your computer's overall performance. The following table lists some features you can upgrade to optimize your hard disk performance: Features Description Upgrade the hard disk Upgrade to the fastest hard disk possible. Hard disk drives come in a variety of different rotation speeds

such as: 5400 RPM (not desired) 7200 RPM (minimum) 10,000 RPM Upgrade the disk interface Upgrading your disk interface will greatly improve the throughput of data to and from your hard disk drive. For optimal performance, consider upgrading to SATA3. This will upgrade your speed to 600 Mbps. A mostly full drive can run slower than a mostly empty one. The following table contains various methods you can use to clean up a disk drive: Utility Description Disk Cleanup Disk Cleanup helps manage disks by locating and disposing of files that can be safely removed from the disk by: Emptying the Recycle Bin Deleting temporary files such as those used by a web browser or for application installation Deleting installation log files Deleting offline files Compressing old files You can type Cleanmgr at the command prompt to run Disk Cleanup. Disk Defragmenter Disk Defragmenter optimizes the performance of your hard drive by joining fragments of files that are in different locations on your hard drive into a single location. Some files, such as certain system files, cannot be moved. To improve defragmentation, disable programs that run in the background like screensavers and virus software. Any disk access while Disk Defragmenter is running (whether to read from or write to the disk) will slow down the defragmentation process. The more information that is on the drive, the more time it will take to defragment the drive.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
