Optimizing and Protecting Hard Drives ‐ Chapter # 9
Optimizing and Protecting Hard Drives ‐ Chapter # 9 Amy Hissom Key Terms antivirus (AV) software — Utility programs that prevent infection or scan a system to detect and remove viruses. McAfee Associates’ VirusScan and Norton AntiVirus are two popular AV packages. backup — An extra copy of a file, used in the event that the original becomes damaged or destroyed. boot sector virus — An infectious program that can replace the boot program with a modified, infected version of the boot command utilities, often causing boot and data retrieval problems. buffer — A temporary memory area where data is kept before being written to a hard drive or sent to a printer, thus reducing the number of writes to the devices. chain — A group of clusters used to hold a single file. child, parent, grandparent backup method — A plan for backing up and reusing tapes or removable disks by rotating them each day (child), week (parent), and month (grandparent). cross-linked clusters — Errors caused when more than one file points to a cluster, and the files appear to share the same disk space, according to the file allocation table. defragment — To “optimize” or rewrite a file to a disk in one contiguous chain of clusters, thus speeding up data retrieval. differential backup — Backup method that backs up only files that have changed or have been created since the last full backup. When recovering data, only two backups are needed: the full backup and the last differential backup. disk cache — A method whereby recently retrieved data and adjacent data are read into memory in advance, anticipating the next CPU request. -
Illustrated Tutorial: Creating a Bootable USB Flash Drive for Windows XP
Illustrated tutorial: Creating a bootable Version 1.0 February 15, 2007 USB flash drive for Windows XP By Greg Shultz The ability to boot Windows XP from a USB Flash Drive (UFD) offers endless possibilities. For example, you might make an easy-to-use troubleshooting tool for booting and analyzing seemingly dead PCs. Or you could transport your favorite applications back and forth from home to work without having to install them on both PCs. However, before you can create a bootable UFD, you must clear a few hurdles. You saw that one coming didn’t you? The first hurdle is having a PC in which the BIOS will allow you to configure the USB port to act as a bootable device. The second hurdle is having a UFD that that will work as a bootable device and that’s large enough and fast enough to boot an operating system such as Windows XP. The third hurdle is finding a way to condense and install Windows XP on a UFD. If you have a PC that was manufactured in the last several years, chances are that its BIOS will allow you to configure the USB port to act as a bootable device. If you have a good qual- ity UFD that’s at least 512 KB and that was manufactured in the last couple of years, you’ve probably cleared the second hurdle. And once you’ve cleared those first two hur- dles, the third one is a piece of cake. All you have to do is download and run some free soft- ware to create the bootable UFD. -

More detailed logs are found on the end point. These logs are described below. In VDS v5.4+, the logs are found in the following folder path: C:\programdata\cloudworkspace In previous version of VDS, they can reside in the following paths: C:\Program Files\CloudWorkspace\ C:\Program Files\CloudJumper\ C:\Program Files\IndependenceIT\ File type also varies by VDS version, log files are either .txt or .log files found in sub-folders of the above outlined path. Automation logs CW VM Automation Service log CwVmAutomationService.log The CW VM Automation service is a Windows Service that is responsible for the management of all Virtual Machines in the deployment. As a Windows Service it is always running in a deployment, but has two main modes of operation: Scheduled Task Mode and Event Mode. Scheduled Task Mode consists of activities that are performed on the VMs as part of a schedule, including collection sizing and performance data, rebooting VMs, checking on state (on or off) vs rule sets generated by the Workload Schedule and Live Scaling features. -

Implementing Hard Drives 10
All-in-1 / A+ Certification Exm Gde, 6th Ed. / Meyers / 6311-3 CHAPTER Implementing Hard Drives 10 In this chapter, you will learn how to • Explain the partitions available in Windows • Discuss the formatting options • Partition and format hard drives • Maintain and troubleshoot a hard drive From the standpoint of your PC, a new hard drive successfully installed is nothing more than a huge pile of sectors. CMOS sees the drive; it shows up in your autodetect screen and BIOS knows how to talk to the drive; but as far as an operating system is concerned, that drive is unreadable. Your operating system must organize that big pile of sectors so you can create two things: folders and files. This chapter covers that process. Historical/Conceptual After you’ve successfully installed a hard drive, you must perform two more steps to translate a drive’s geometry and circuits into something usable to the system: partition- ing and formatting. Partitioning is the process of electronically subdividing the physical hard drive into groups of cylinders called partitions (or volumes). A hard drive must have at least one partition, and you can create multiple partitions on a single hard drive if you wish. In Windows, each of these partitions typically is assigned a drive letter such as C: or D:. After partitioning, you must format the drive. This step installs a file system onto the drive that organizes each partition in such a way that the operating system can store files and folders on the drive. Several different types of file systems are used in the Windows world. -
No More Excuses: Windows 7 Makes It Easy to Manage Computer Power
• Products that earn the ENERGY STAR® prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. www.energy star.gov NO MORE EXCUSES: WINDOWS 7 MAKES IT EASY TO MANAGE COMPUTER POWER CONSUMPTION ORGANIZATION-WIDE Here’s how you can take advantage of Windows 7’s new power management features The University of Wisconsin at Oshkosh is no stranger to the idea of sustainability. In 2003 it became the first university in the state to join the Environmental Protection Agency’s Green Power Partnership. Its green initiatives also earned the university high marks from the Sierra Club, which ranked the university nationally in its Cool Schools survey. Given this commitment to green, it’s no surprise that the university first deployed computer power management back in 2005, and that it was one of the first Energy Star power management success stories. At that time, the University’s computers ran the Windows XP and Windows 2000 operating systems, neither of which included native tools for the central administration of power management features. To implement power management settings on these machines, the University used third-party software from ENERGY STAR called EZ GPO. For detailed information and resources concerning Now that Windows 7 has CPM client management features built in, it’s much the power management of easier to administer power management. This case study will show you how the University of Wisconsin at Oshkosh took full advantage of computer power PCs running Windows XP, management features on Windows Vista and Windows 7 clients managed by please see the ENERGY STAR Windows Server 2008. -
Solarblizzard
Security Now! Transcript of Episode #800 Page 1 of 27 Transcript of Episode #800 SolarBlizzard Description: This week we open the New Year taking a longer look at fewer topics since the bad guys were apparently enjoying their New Year holiday, too. So we look at an interesting kludge that's been forced upon Chrome by ill-mannered antiviral scanners. We need to warn all enterprise users of Zyxel network border security products of another recently discovered built-in backdoor. We look at the rise in IoT compromise swatting attacks and a series of new flaws and vulnerabilities in the PHP Zend and Yii frameworks. We have a quick bit of miscellany to share, then I want to explain a lot about the value of trimming SSDs and newer SMR drives. And we'll conclude by catching up with what will hopefully be the last news, for a while at least, of the disastrous SolarWinds breach and intrusions.

Steve Gibson is here with a defunct football; a very bad AV security practice that Chrome has had to do something maybe even worse to fix. We'll talk about the built-in password access in 100,000 Zyxel firewalls, VPN gateways, and access point controllers; an update on SpinRite 6.1; and a whole lot more.
