SpinRite 6.1/R2 - U.2 Drive Attached With a M.2/U.2 Adapter Not Recognized

  • SpinRite v6.1 Release #3
    Guest:
    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.

    (You may permanently close this reminder with the 'X' in the upper right.)

Yeah, I know, it's a bit of a stretch, but have an Enterprise Micron 9300 Pro U.2 NVME/SSD in my AMD X570 based system. The drive is attached to the primary NVME/M.2 slot on the motherboard using a M.2 to U.2 Host Adapter (https://www.amazon.com/gp/product/B07VB6L8SJ). I just picked up SpinRite 6.1/R2 to try to do maintenance, but it's not seeing the drive. I'm guessing it's something to do with the adapter, but wondering if anyone else has anything similar and gotten it to work.
 
Can you see the device in the BIOS? Can you see it in FreeDOS? SpinRite doesn't have NVMe drivers so it's not going to be able to see it on its own, it will be requiring support from the BIOS and FreeDOS.
 
Yes, I can see it in BIOS, but it's UEFI, which I think I heard Steve say something about not working probably until SR 7. I don't see it in SpinRite, but will check to see if FreeDOS sees it. I assume it won't though.

Edit: Checked and FreeDOS doesn't see it. I'll just wait until there's a release that supports UEFI/NVME :)

@Meatball I have the 570 and can get Spinrite to see my NVME drive on the internal m.2 port.

I'll check my settings tomorrow but I think you have to switch it out of optane mode from memory. This makes it accessible to the BIOS.

Well, good news, sorta. By setting 'Storage Boot Option Control' in my UEFI/BIOS to 'Legacy Only' as opposed to 'UEFI Only', SpinRite/FreeDOS sees the NVME Connected drive. Looks like it might take 27+ hours to do Option 3 maintenance, but at least I can see it now. :)
