How to Perform a Full Manual Defrag of Your HDD under Vista

1. To view a file fragmentation analysis of (say) your C: drive, type:

defrag c: -a -v

The “-a” parameter tells the defragger to perform a fragmentation analysis. The “-v” option tells it to be verbose in its report. If you want a report on drive D: or some other drive, substitute that drive letter in place of c:.

Be aware that defrag may tell you that you have no fragmented files even if you have some. On NTFS partitions, the reporting function of defrag does not consider fragmented files with fragments greater than 64 MB as fragmented. If you need truly detailed information, you may have to consider getting a third party defragmenter such as those listed on the Free Defragmentation Utilities page on thefreecountry.com.
2.

To defragment a particular drive, say C:, type:

defrag c: -v -r

The “-r” option tells the defragmentation utility to treat files that are fragmented with 64 MB fragments or larger as though they are not fragmented. This partial defragmentation is the default for “defrag”, and it’s the only way the GUI defragmenter in Vista works.

You can also force the defragmenter to defragment everything. That is, even if the file fragments are larger than 64MB, the Vista defragmenter will still attempt to put the file into contiguous sectors. To do this, run the defragger with the following options:

defrag c: -v -w

As you have probably have guessed, “-w” tells the Vista defrag tool to do a full defragmentation. All file fragments will be consolidated where possible.

  1. Yeah, I agree with your opinion that a simple disk defragmentation can not be missed when trying to get a faster computer for it helps to easily make the computer run faster by rearranging them stay at the same single place and insist on regularly defragmenting my computer. When searching the Internet, I have found an article taking about this in details as you can get more further information here: http://ezinearticles.com/?Disk-Defragmentation—Make-Computers-Run-Faster-Soon&id=3162755. Believe me, it is really worth reading!

  2. I purchased an automatic defragger to work on my Vista drives and honestly i have no regrets on spending the extra bucks. Vista does do a background thing on its own andperhaps efficiently, but for my larger drives which get fragmented very fast, i would have no way of knowing their state. The automatic program has a GUI and also runs in the background defragging every now and then without affecting other operations. Saves me a lot of bother.
