  • DNS Benchmark v2 Release 5 with Consultant License
    Guest:
    If you own any earlier release of our DNS Benchmark you may immediately download its release #5 replacement. Running an earlier release will detect the new release and help you upgrade.

    Although this release is cosmetic, appearance matters and affects ease of use. The biggest change, as seen in the image above, is that the DNS Benchmark now has a traditional Windows application menu to more fully expose its many features. This release is also "Consultant License Aware" and GRC will now issue a Consultant version when owners have previously purchased four "Personal Use" licenses. If you have previously purchased four DNSB licenses, or if you wish to upgrade your "Personal Use" license to Consultant, GRC's purchase process will direct you through that process.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Maintenance of an SSD

The drop in performance of an SSD due to bit-rot has been established, and running SpinRite level 3 is one method of restoring the performance. But is it necessary to do this on 100% of the drive or just the slow portion. For example, ReadSpeed and the Spinrite Benchmark show that the first 25-30% of the drive is slower than the rest. Would running SpinRite level 3 on just the first part of the drive be sufficient? Does the SSD's allocation of sectors to any physical area of the drive have an impact?

Absolutely!!! The slowness of the first 25-30% of the drive, where the OS, Apps, and data are located, is due to mainly to "Read Fatigue", i.e. the repeated reading of the same locations. A Level 3 refresh of just that slow area is all that is needed.

There is absolutely NO point to doing a Level 3 on the fast (and likely not yet used) areas of the drive.
