Troubleshooting Disk Management

This lab discusses some common disk management procedures. You can use storage media such as CD-R, high capacity floppy, tape drive, DVD-R, or a secondary hard drive. Windows has a backup utility that can be used to schedule backups of your files.

It is also a good practice to clean unnecessary files off your hard drive. Windows has a utility called Disk Cleanup that can delete some of these files for you.

You might also find it necessary to compress files to save hard drive space. Windows has a built-in file compression utility, but there are many third-party utilities available as well.

For security reasons you might need to encrypt your files. The Encrypting File System (EFS) included with Microsoft Windows 2000 is based on public-key encryption. Each file is encrypted using a randomly generated file encryption key. Each file has a unique file encryption key, making it safe to rename. If you move a file from an encrypted folder to an unencrypted folder on the same drive, the file remains encrypted. If you copy an unencrypted file into an encrypted folder, the file remains unencrypted. You don't have to decrypt a file to open it and use it. EFS automatically detects an encrypted file and locates a user's file encryption key from the system's key store to open the file.

Resources

  • PC-compatible desktop/tower computer system—Customer supplied desktop/tower hardware system or Marcraft MC-8000 Computer Hardware Trainer or suitable PC hardware trainer with Windows 2000 installed

  • A blank 1.44MB floppy disk

Procedure

In this lab you will create, back up, restore, compress, and encrypt a WordPad Document. You will manage the resources on your computer, such as the disk drive, to optimally use space and resolve issues revolving around resource shortage.
