Just install it and let 'er rip! - Diskeeper 2007 is now available!

by Michael 17. October 2006 14:23
What best describes Diskeeper 2007? I think beta tester Michael Ratledge (an IT security pro) said it best - "Just install it and let 'er rip!" Diskeeper 2007 does what an automatic defragmenter should do. It defragments files on-the-fly without any impact on the system. Powered by new InvisiTasking technology, Diskeeper is the only technology that can truly deliver transparent operations. Whether you are running a mission critical 24/7 enterprise server, or the latest graphics-intensive game, Diskeeper 2007 intelligently uses only unused system resources (if and when they are available). InvisiTasking goes far beyond the limitations of I/O and CPU throttling. There's simply no comparison. What does that mean? It means no more need to turn off your defragmenter, schedule at "off" hours, or manual defrag when you have a few minutes. And, Diskeeper 2007 is simple for the user - no need to figure out "settings" or what "type" of defragmentation is best for your system. Diskeeper does it for you, intelligently and dynamically determining what your system needs for peak file system performance! Check out our product pages at diskeeper.com for more info, then download the trialware and take 'er for a spin!

Invisible Software?

by Michael 14. October 2006 03:20
Below is the first part of a white paper on an amazing new technology our R&D team invented. We have big plans for this technology. I'd like to hear other venues where you think this technology could help? What programs are you running that could leverage this? BTW: This report is a general overview of technologies in order to provide a better understanding of certain limitations inherent in modern operating systems. It is not a scientific study. --- BACKGROUND MULTITASKING OVERVIEW Multitasking is a method for sharing system resources so that multiple processes can appear to run simultaneously. An example would be the ability to run both a word editor and a spreadsheet application at the same time. However, a component in a general purpose computer, such as the CPU, can only execute one task at a given time. Multitasking presents the illusion that all execution is occurring simultaneously by implementation of a thread scheduling system. It is in essence virtualization of the CPU, designed to fool applications into believing they own the CPU exclusively. More powerful and faster CPUs can execute larger tasks or execute more in a given span of time. Multiprocessing extends the principles of multitasking to multiple CPUs, actually allowing threads to run simultaneously, where multitasking only feigns this behavior. Multiprocessing, like multitasking, is still limited in processing capacity to one action at a time on a given CPU. For the purposes of this paper, multitasking will be used to refer to the operating system's thread handling.

Diskeeper and Vista

by Michael 14. October 2006 02:47
We've made Diskeeper 10 beta versions available since earlier this year. While we figured to learn more about Vista in the process, it was done primarily for those of you on the edge of new technology who wanted to use Diskeeper as you tested Vista. I noted in earlier blogs that we're very strict about the quality of software we send out, including beta software. That is why we went through stringent testing before we made each build available. That, in turn, means a time gap between a Microsoft build release and a Diskeeper beta release. It is a trade-off of time for quality. To date, we have received no major bugs reports (only a few install issues related to earlier UAC problems fixed in later builds of Vista). We've watched Vista "grow up" over the past year into a really solid and stable OS. In the last few weeks/month we've been outpaced by Microsoft as they near their release. While it only takes a few days to test and change the code to release a new beta, these Diskeeper beta versions are at the mercy of other projects. Our most important yearly project has been wrapping up, thereby taking all development and test time from other projects. That of course, is the next release of Diskeeper. At this time, the likelihood is that the next iteration of Diskeeper for Vista will be based on the next Diskeeper platform. And, when Vista hits the streets, Diskeeper will officially support it.

Identifying Common Reliability/Stability Problems Caused by File Fragmentation

by Michael 6. October 2006 20:15
Earlier this year I wrote a white paper on fragmentation's effect on system and application reliability, presenting information about the root cause of the issue. Below is the first section of that paper. You can read the entire document in our Knowledge Center. An Overview of the Problem Having all program and data files stored in contiguous form on the hard drive is a key factor in keeping a system stable and performing at peak efficiency. Though unavoidable, the moment a file is broken into pieces and scattered across a drive, it opens the door to a host of stability/reliability issues. Having just a few key files fragmented can lead to crashes, conflicts and errors. The principle of fragmentation's impact on system or application reliability is the timing out of a requestor or service provider in collecting/reassembling fragmented data. This principle holds true for both IP datagram fragmentation and file/disk fragmentation.

Diskeeper Hugs a Tree

by Michael 4. October 2006 19:54
Due to a record pace for company software volume license sales in 2006 (thanks to our customers volume sales have been up 4 quarters in a row), Diskeeper Corporation is returning the favor to the environment. The next Diskeeper version will be using chlorine-free, recycled paper for its retail packaged Diskeeper products. And, it's a practice we plan to continue for the future. http://www.marketwire.com/mw/release_html_b1?release_id=168621 The huge revenue boost also allows us to concentrate on the expansion of our R&D teams - we actually have two independently operating Research teams in addition to our product-specific development groups. It's the Research program teams that have produced some of the current defragmentation pioneering technologies in Diskeeper 9 & 10, as well as the industry-wide ground breaking new technology that is at the core of the new upcoming release. A recent key acquisition to the team is Rick Cadruvi, the original co-creator (with our CEO) of Diskeeper for OpenVMS (back in the 80's). Rick was well known as one of the premier industry experts on OpenVMS operating system design. With many years of in-depth technical expertise on Windows, he re-joins us as a technology leader, and is already quite busy inventing great new technologies. Look forward as we (the staff of Diskeeper Corporation) return our thanks for purchasing Diskeeper Corporation products in the form of revolutionary and technology leading new products to make your computers run faster and more efficiently.
