  • SpinRite v6.1 Release #3
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • 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.

The USB boot drive did not show up initially. I had to enable legacy mode in the bios first. No biggy, it worked great after that change.
Will there be EFI boot support in the future?
Will there be EFI boot support in the future?
Yes! The UEFI/EFI alternative to the BIOS didn't even exist in 2004 when SpinRite 6.0 was released. So it was never an issue then. And it hasn't really been an issue until much more recently. But it is today. So, due to the clear need for SpinRite to support UEFI booting from here on, SpinRite's development Roadmap was resequenced to move UEFI support for USB and NVMe. We wish it was possible to do everything at once, since older BIOS-based systems would rather have native USB and NVMe support. But with SpinRite v6.1, those older BIOS-based systems will be getting a huge boost with SpinRite's native IDE/SATA/AHCI support. So we then want to make that available to all UEFI systems, after which all systems will be able to benefit from all further advances, which will be to immediately work on adding native USB and NVMe support.
