What disk volumes are supported?

Disk MD supports FAT32 and NTFS (New Technology File System).

Windows Vista & XP include defragmenters. Why would I need Disk MD?

Disk MD is an easy to use, customizable defrag tool that provides you with a detailed view of the defragmentation process. In addition, Disk MD is the first defragment product on the market to defrag system restore point, which are arguably the most fragmented files on a drive and usually locked and un accessible to applications.

What is fragmentation?

When Windows writes a file to the hard disk, quite often it has to break the file into multiple pieces. As this happens over days, months, and years, the drive becomes fragmented. The impact to performance is huge. It is not uncommon for a very fragmented file to take 60 times as long as an unfragmented file.

Can I use my system while the defrag is running?

Yes you can. However, it is not recommended because the system is constantly changing files. The impact on overall performance varies with the configuration of your system.

Will running processes like your firewall, anti-virus utility interrupt the defrag process?

The processes will not not interrupt the defrag process. However, it is always recommended that everything be closed down during defragmentation. Applications sometimes create and delete files, including temporary files which can hinder the effectiveness of defragmentation.

Could I lose access to some files while Disk MD is performing a defrag?

Yes, defragmentation creates an exclusive lock on files while it is moving them.

What if I have a technical question?

For any technical questions–before or after you purchase the product–please use our Disk MD forum. That way, you can get quick answers and share your questions with other users. If you have a computer issue unrelated to Disk MD, please use our support forums.

Percent of Data Fragmented

Of the total amount of data on the disk, the percentage of data that resides in fragmented files. Generally, the lower the number, the better the system performance. If the percent of data fragmented is very high, but the number of files fragmented is low, this indicates large files holding a majority of the total data on the disk. Note: These results may differ slightly from the numbers shown by the analyzers in defragmenting utilities due to differences in the way used and available disk space is counted.

Percent of Files Fragmented

Of the total files and directories on the disk, this is the percentage of files and directories that are broken into two or more fragments. Lower numbers indicate better system performance potential. Note: These results may differ slightly from the numbers shown by the analyzers in defragmenting utilities due to the way files are counted.

Total Fragmented Files

The actual number of files on the disk that are fragmented. Even a freshly defragmented drive may have some fragmented files, particularly if you use the defragmenters that are bundled with Windows. Those versions often cannot swap files or system files, which means they cannot totally the drive.

Total Excess Fragments

Total number of extra file fragments on the drive. Ideally this number should be close to zero.

Average Fragments per File

Average number of fragments in each file. Ideally this number should be close to one.

Most Fragmented Files

The files on the system that are shown to be the most fragmented. If the fragment count is over 100 then your system performance is impacted.

System Restore Data

The data that supports the System Restore feature of Windows XP. System Restore enables administrators to restore their computers to a previous state without losing personal data files (e.g. Word documents, graphic files, e-mail).
