New White Paper From Windows IT Pro

by Michael 10. April 2009 10:25

Check out the new study done by IT guru David Chernicoff on the "Impact of Fragmentation on Servers" here.

It is also posted on SlideShare here.

Testing was done on various server-based applications such as file hosting, SQL, Exchange, virtual machines, and more, with performance increases in the range of 30%+.

If you're a Server Admin or an IT consultant /VAR for a company, this paper can really help you make a solid case for getting Diskeeper into use on the company/client servers. The "bang for buck" is hard to beat.

If you subscribe to the Windows IT Pro mag, keep an eye out for the May issue which will have an insert with this paper. And, if you are heading to Tech Ed next month (in Los Angeles), you'll get a free copy of the mag with your "attendee kit". We'll be there as well, so stop by our booth.



New Diskeeper 2009 Update (13.0.844)

by Michael 7. April 2009 10:21

Below is a list of what's new in the latest Diskeeper update. We'll be rolling out this update (you'll be notified from the Check For Updates feature in Diskeeper) over the next couple of weeks, starting with the English language updates first. Shortly thereafter you'll be able to get the update in all other languages currently supported: French, German, Spanish, Italian, Russian, Japanese and Simplified and Traditional Chinese.

1. Added support for management via SCOM 2007.
2. Added code to synchronize access to WMI data structures between multiple threads.
3. Updated content and existing functionality in the Diskeeper Group Policy template file.
4. Added a selection to enable/disable Operations Manager event logging through Group Policy.
5. Added support for the new ADMX Group Policy template format.
6. The "Before and After Performance Report" previously included only in trialware is now available in the full product.

7. Fixed a problem with uninstalling Diskeeper Service through Group Policy.
8. Corrected several minor problems/inconsistencies with the Performance Report:
a. Use low performing file size rather than just the number of files to show as percentage in the graph to make it visually consistent with the Volume Map File Performance View.
b. Replace the Fragmentation Percentage data with Percentage of low performing files (analogous change was made to the Job Report).
c. Disabled the Trialware Expired report selection when there is not enough data for this report so that no empty report is displayed.
d. Corrected low performing directories data.
9. Fixed a problem with low performing files data reported by manual defragmentation.
10. Fixed a bug in the Job Report where inconsistent data was displayed between the Findings and Recommendations and the Health sections.
11. Included Most Fragmented Files data in the Job Report window rather than in a separate pop-up.
12. Minor corrections for Diskeeper service in certain rare environments.
13. Minor corrections to the File Exclusions feature.
14. Made the delay at the end of the boot-time engine processing adjustable through a registry key.
15. Fixed a UI bug on the Boot-time Defragmentation page by moving the "Run boot-time defragmentation even if this volume it being used…" selection under the "scheduled reboot" radio option in the upper section.
16. Fixed a display problem with Trialware where under certain circumstances a large number of days to expiration would be displayed.
17. Fixed an error when adding a higher (incorrect) version license file to the product by adding validation code.
18. Fixed error where when Diskeeper push installed through DK Admin displays an error "Unable to retrieve license data". This could also cause numerous trialware roll-up notification windows at the same time.
19. Fixes to the Trialware roll-up tray interaction; Corrected mouse-over text , Fixed the launch Diskeeper UI , context menu action
20. Fixed inconsistent expiration data in the Trialware Expired Performance Report where the expiration date and the number of days since expiration would be inconsistent.
21. Diskeeper will now correctly use the default Web browser when checking for updates.

Note that Diskeeper Server now also adds support for Windows Server 2003/2008 Datacenter (contact your sales rep for this build).

UPDATE: June 22, 2009: The build that was officially released was 13.0.844, which included all the above fixes. The 842 build was a Tech Support/Field Test build and had a limited release. I've updated the post title to reflect this as the 13.0.844 change log.



Fragmentation in action (a video)...

by Michael 3. April 2009 10:21

If you've ever stopped by a Diskeeper booth at a trade show in the past few years, you may have seen our clear-case PCs.

Inside those clear case PCs we have WD Raptor X drives with a see-through cover. That clear cover allows you to watch the disk head moving across the platter.

When you defragment one drive and leave one fragmented, it makes for an interesting visual side-by-side comparison. That's a test we videoed and posted on YouTube.

Defragmented drives, mean less wear and tear over the life of the drive so it lives longer. It also means less energy used to power and cool the PC.



Field Test Sites Running Hyper-V Needed

by Michael 12. March 2009 10:19

We're looking for some current Diskeeper customers that are interested in getting a first look at a new technology for Microsoft's Hyper-V platform. Testing will start in a few weeks and we have a few openings left that we need to fill.

If you are using Hyper-V and are interested and able to test on it, simply fill-out a Non-Disclosure Agreement (NDA) located here.

Fax the signed NDA to:
Fax: 818-252-5514

Please add the following to the Fax cover page:
Attn: Field Test Administrator/Hyper-V Field Test

Alternatively you can email the signed NDA (scan in the pages with your signature) to our Field Test administrator. Please add "Hyper-V Field Test" in the subject line.



Quick turnaround from Kaspersky

by Michael 11. March 2009 10:16

Kaspersky Anti-Virus is reporting a false alarm (known as a False Positive in software security terminology) on Diskeeper downloads as of late yesterday. If you tried to download our software (Diskeeper) from our website, it triggered a "Trojan" alert in Kaspersky.

The issue was reported to Kaspersky yesterday and they verified Diskeeper was clean (no viruses) and rapidly released and update to their software to correct this. By early this morning they reported that the problem has been fixed and that customers should update their Kaspersky AV software.

Our QA team has verified this fix works, but recommend users of Kaspersky AV reboot their systems after updating and prior to downloading Diskeeper. If you do not reboot, you won't get that "Alert" message, but we found that you will still get a "Warning" about the Diskeeper download, so please reboot if possible.

Thanks to the team at Kaspersky for such a quick turnaround!
