Downloading Latest SR 6.1 Beta?

  • 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.)

I remember hearing on SecurityNow! that we'd be able to download a beta version of 6.1.
I see it was done on this thread but I can't seem to find the link for it.
Can someone point me in the right direction?
Thanks
 
Hi @GregM. Due to a problem found on drives with certain serious errors causing the drive to crash/lock-up, Steve is rewriting his key algorithm, and then it will probably require a good round of testing. This is truly alpha level software and should NOT be run on data you value (at least without a backup.) Due to it only being Alpha, @Steve requires you to participate in his GRC newgroup for SpinRite development. If you're interested in doing so, start here: https://www.grc.com/discussions.htm Please carefully read the section on "Newsreader Configuration:". Once you arrive in the newsgroup, you would wait for Steve to post about the new version of SpinRite, which will require you to go to the specified URL and use your SpinRite 6.0 purchase information to complete a personalized download.

Alternatively, if you are concerned of the risk of the alpha quality, you can wait until it enters beta, which is probably still a few months off.
 
Got it. Thanks for the update.
Just bought some new drives and was going to run it on them to make sure they were good out of the box, so no data in jeopardy in this case.
Will follow through as suggested.
Cheers,
G.

I’m sorry, I’m confused. I can’t find “Newsreader Configuration“. Could you give me the link please? And once there, is it easy to join the group? From what Steve was saying back in January the version available then was finished and working well and he was waiting for more testing to be done on weird or obscure drives. Where would I find the version he was talking about in January? I’ll give that one a go.

You really should read the whole page (or at least skim it, as it has all the advice for new users). As you're reading, you'll come across the section that you need to pay extra attention to, looking like:

I know it's difficult to have to use a newsgroup, but this *IS* Steve's requirement, not mine. He already has many hundreds of users who are testing, so I guess he knows his own users well enough to know how to limit the incoming testers to the sorts of people he wants to be using an early alpha. If you make the effort, just post to the SpinRite dev newsgroup asking for advice on using the previous version you'd like to try, and there are very good odds that Steve himself will reply directly to you.

... a few months off ... are we really looking at 2024 before us common folk can get 6.1?

I’m trying to join the news group but I’m having trouble 🙄. If I were to pull out the 4T western digital HDD from my server and ran SR 6.0 level 4 on it, would SR at least fix any errors in the first 2.2TB? I seem to remember me trying SR over a year ago when I first thought that there was a problem with the drive and SR told me “Everything is weird, the disc info is too crazy to cope with, don’t proceed, doom, gloom and disaster awaits if you do”. I think that those were the exact words 🤔. So I didn’t proceed as I was a wimp.
 
Okay, well I may have good news for some of you with SR 6.0 working for you, there is a bug patch released, unofficially, but recommended by @Steve. It addresses the case where you receive a Division by Zero error when Dynastat tries to recover a bad sector. I doubt it will help if you're facing the issue of a drive that is too large (greater that roughly 2TB) though. Anyway, here's a quote direct from Steve's post in the newsgroup:

Paul's "MDFYSR60" utilities are now officially documented and
available for download from GRC:

The new page in SpinRite's small knowledgebase collection:
https://www.grc.com/sr/kb/b04e.htm

MDFYSR60's presence among GRC's freely downloadable utilities:
https://www.grc.com/freeupdated.htm

And I added an entry near the top of SpinRite's FAQ page:
https://www.grc.com/sr/faq.htm

I haven't yet looked into updating GRC's purchase and download
system, but I would also like to add notices to the download
page and to the user's receipt page to notify new owners of the
MDFYSR60 utilities. I'll look into that after Tuesday's podcast.
 
Thanks. I'm a bit confused. I used the exe to make an iso which I boot from. How do I apply this patch?

Return to your previous thread and follow the steps here https://forums.grc.com/threads/spinrite-iso-issues.1227/post-8975
Specifically don't run SPINRITE.EXE to create anything. Just copy the file to the USB flash drive. Then copy MDFYSR60.COM to the flash drive.

Open a Windows Command Prompt: Start->run ( or <WinKey>r ) ->cmd->OK
Switch to your flash drive ( assuming it's D: )
C:\Users\{name}>D: <Enter>

and enter the commands:
D:\>attrib autoexec.bat -r -h -s
D:\>notepad autoexec.bat

Add MDFYSR60 to the file and make any other changes you want, such as adding SPINRITE after MDFYSR60 to run it automatically on boot-up.

Save the file, close everything. You should be able to boot and run SPINRITE from the flash drive now.

Ah, I should clarify. I never got it working over USB. I got a new M2, and that is currently running Windows on my laptop. I'm still interested in running spinrite on this drive.
On my Linux desktop, I've got the original M2 with issues mounted by a M2toUSB converter. I create a virtualdrive from that in VirtualBox. Then I load a VM with that driver and the spinrite ISO to boot into spinrite and scan the drive.
Is it possible to modify this ISO? Or I guess I can look into creating a virtual USB?
 
possible to modify
Well since the patch is TSR (terminate and stay resident) you need only run it once before running SpinRite. If the ISO boots but does NOT run SpinRite automatically, then so long as you could find another way to copy the MDFYSR60.COM executable into your virtual environment, you could execute it before starting SpinRite.
