This Document Explains How to Copy Ondemand5 Data to Your Hard Drive
Copying Your Repair DVD Data To Your Hard Drive Introduction This document explains how to copy OnDemand5 Repair data to your hard drive, and how to configure your OnDemand software appropriately. The document is intended for your network professional as a practical guide for implementing Mitchell1’s quarterly updates. The document provides two methods; one using the Xcopy command in a DOS window, and the other using standard Windows Copy and Paste functionality. Preparing your System You will need 8 Gigabytes of free space per DVD to be copied onto a hard drive. Be sure you have the necessary space before beginning this procedure. Turn off screen savers, power down options or any other program that may interfere with this process. IMPORTANT NOTICE – USE AT YOUR OWN RISK: This information is provided as a courtesy to assist those who desire to copy their DVD disks to their hard drive. Minimal technical assistance is available for this procedure. It is not recommended due to the high probability of failure due to DVD drive/disk read problems, over heating, hard drive write errors and memory overrun issues. This procedure is very detailed and should only be performed by users who are very familiar with Windows and/or DOS commands. Novice computers users should not attempt this procedure. Copying Repair data from a DVD is a time-consuming process. Depending on the speed of your processor and/or network, could easily require two or more hours per disk. For this reason, we recommend that you perform the actual copying of data during non-business evening or weekend hours. -
Chapter 6 MIDI, SCSI, and Sample Dumps
MIDI, SCSI, and Sample Dumps SCSI Guidelines Chapter 6 MIDI, SCSI, and Sample Dumps SCSI Guidelines The following sections contain information on using SCSI with the K2600, as well as speciÞc sections dealing with the Mac and the K2600. Disk Size Restrictions The K2600 accepts hard disks with up to 2 gigabytes of storage capacity. If you attach an unformatted disk that is larger than 2 gigabytes, the K2600 will still be able to format it, but only as a 2 gigabyte disk. If you attach a formatted disk larger than 2 gigabytes, the K2600 will not be able to work with it; you could reformat the disk, but thisÑof courseÑwould erase the disk entirely. Configuring a SCSI Chain Here are some basic guidelines to follow when conÞguring a SCSI chain: 1. According to the SCSI SpeciÞcation, the maximum SCSI cable length is 6 meters (19.69 feet). You should limit the total length of all SCSI cables connecting external SCSI devices with Kurzweil products to 17 feet (5.2 meters). To calculate the total SCSI cable length, add the lengths of all SCSI cables, plus eight inches for every external SCSI device connected. No single cable length in the chain should exceed eight feet. 2. The Þrst and last devices in the chain must be terminated. There is a single exception to this rule, however. A K2600 with an internal hard drive and no external SCSI devices attached should have its termination disabled. If you later add an external device to the K2600Õs SCSI chain, you must enable the K2600Õs termination at that time. -

1. Xcopy 2. No, You Cannot Use the Xcopy Command in Your Assignment
Intro to Operating Systems CNET 173 Assignment #4 Windows / LINUX Command Line Commands You are to list twenty-five command line commands of each operating system (WINDOWS and LINUX). That’s twenty- five WINDOWS commands and twenty-five LINUX commands. For each command you are to give: 1. The command a. Description/Attribute of the command b. Syntax of the command and c. A maximum of five Parameters used with the command and a description of the parameter. (If there are less than five parameters, list all parameters associated with the command.) Each command should be numbered and grouped (all WINDOWS commands with WINDOWS commands). Command information should be listed in the 1, a, b, c order listed above (i.e. command, description, syntax and parameters). This assignment must be typed and submitted through CANVAS. It should include a title page consisting of your name, course name, number, day and time, assignment name, instructor’s name, and due date and the assignment instructions. Example listed below. Windows Command Line Commands 1. xcopy a) Description - Copies files and directories, including subdirectories. b) Syntax xcopy Source [Destination] [/w] [/p] [/c] [/v] [/q] [/f] [/l] [/g] [/d[:mm-dd-yyyy]] [/u] [/i] [/s [/e]] [/t] [/k] [/r] [/h] [{/a|/m}] [/n] [/o] [/x] [/exclude:file1[+[file2]][+[file3]] [{/y|/-y}] [/z] c) Parameters /w : Displays the following message and waits for your response before starting to copy files: Press any key to begin copying file(s) /p : Prompts you to confirm whether you want to create each destination file. /c : Ignores errors. /v : Verifies each file as it is written to the destination file to make sure that the destination files are identical to the source files. -
