When you scan a volume on a Windows Server 2003-based computer by using the chkdsk /r command, you receive a status message that resembles the following:

CHKDSK is verifying file data (stage 4 of 5)...
0 percent completed. 
1 percent completed. 
2 percent completed. 
3 percent completed. 
Windows replaced bad clusters in file <number>
of name <file name>.
100 percent completed. 
File data verification completed.
CHKDSK is verifying free space (stage 5 of 5)...

This status message incorrectly indicates that Windows replaced bad clusters. This status message can occur if the following conditions are true:

• The current volume has a compressed file.
• The size of the compressed file is larger than 4 gigabytes (GB).

Consider the following scenario:

• You download a compressed (zip) file from the Internet to a computer that is running one of the following operating systems:
  • Windows Vista
  • Windows Server 2003 Service Pack 1
  • Windows Server 2003 Service Pack 2
  • Windows XP Service Pack 2
• You save this file to a disk that is formatted by using the NTFS file system.
• You extract the files from the compressed file by using the Extract All Files wizard.

In this scenario, the modified date of the extracted files changes to the date that you extracted the files.

Note: This problem does not occur when you use a third-party tool, such as WinZip, to extract the files.

When you use WinZip to extract a compressed file that has a .zip file name extension on a Windows Vista-based computer, you receive an error message that resembles the following:

This file was compressed using an unknown compression method. Please visit www.winzip.com/wz54.htm for more information. The compression method used for this file is 98. error: no files were found – nothing to do

So you’ve downloaded a zip file and now you need to open it. Maybe you need to send some files to a friend via e-mail, but they need to be in a zip file to make the trip. Don’t worry about installing any software, Vista can handle zip files in a snap. There are many ways to do it as well. I saw a post at Maximumpcguides and thought why not do an illustrated guide to how I use Vista to zip and unzip. Keep reading →
