SpinRite 6.1 penetrating RAID?

  • 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.

I think I recall Steve mentioning several years ago that a future version of SpinRite would be capable of piercing "thin" RAID.

I remember understanding at the time that this might mean that, when using Onboard RAID (rather than a standalone RAID card), it might be possible to get SpinRite to scan the individual drives directly rather than having to rewire them and/or reconfigure the BIOS. I'm not sure whether I was understanding correctly, and even if I was, this might no longer be true, or it might have been referring to SpinRite 7.x.

I'm running two-drive RAID-1 mirroring using BIOS-based onboard RAID. Anyone know whether, with SpinRite 6.1, I will be able to run SpinRite on the individual drives under my current configuration without any rewiring or BIOS reconfiguration?
If the BIOS will show separate drives to DOS, SpinRite will see them as separate drives. I imagine it doesn't do this, so neither will SpinRite 6.1. Who knows what features SpinRite 7.x will bring? Maybe, if we're lucky, we'll know some time in 2025.

In this case with bIOS RAID you either would have the RAID show up as a single drive, with possibly the actual drives showing up as another set of drives, or it is totally hidden. If BIOS sees individual drives SR will run on the actual drives, and do each one in turn. If it does not show the drives at all you would need to first record details of the RAID configuration, then undo the RAID, reboot, and run SR to do each drive separately, and then redo the RAID setup using the stored parameters. In any case you really want to have a backup that works first, as RAID is not a backup.
