Task 2

Clean up tools;

Clean up tools such as the "Disk Defragmenter" in System Tools make your hard drive work faster by re-allocating disk space so that files which have been broken up and spread about when originally saved, are 'put back together'. When I say the files have been 'broken up' this simply means that when the computer saves, for example, 10MB of data, there may not be 10MB free together so it will put 5MB somewhere, 3MB somewhere else, and the last 2MB somewhere else again, and defragmenting the drive moves all the different bits of files together and puts the 10MB together, making it easier to retrieve files.

Drive formatting;

Drive formatting is basically wiping a drive completely so you can start a fresh and either re-install the/an Operating System or add new data. Obviously different Operating Systems or devices/drives use different file systems, therefore you need to make sure you format the drive accordingly (with the correct file system) before you re-install/add data. Flash Disk Drives are formatted with the FAT file system, Windows Operating Systems use ntfs and fat32, and Linux Operating Systems use reiserfs, ext2 and ext3.
