Can you run SpinRite on a Mac (and how?)

  • 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.)

Not a Mac user, so I may not be able to help you, but I can tell you SpinRite doesn't run under Windows, at least not in the way you want it to. 6.0 runs under Windows to allow you to build a USB device or ISO image to boot DOS, where it is built to run. Using your Windows image, try downloading and running the ReadSpeed utility and see if it will help you build a DOS bootable USB device. If you can get it to boot and run ReadSpeed, then you can put the SpinRite image on there and run that too.
 
It shouldn’t work on an Intel Mac.
SpinRite still depends on BIOS/CSM boot mode, something all recent Macs never had. It will require an UEFI-compatible version, which I believe is planned for SR7.

Some older Intel Macs, which were compatible with Windows XP, did have a CSM. I don’t know if they supported it to a level compatible with SR.
 
I'm befuddled. I managed to DL SpinRite R11.exe on my Mac, formatted a USB drive with Pi Imager, transferred to my spare PC, fixed power issue, booted Win 10 and SR-R11.exe will not run. Error 1, not compatible, Error 2, not built for this OS.
Suggestions?
SpinRite R11 is a development test release. As noted by PHolder, it requires a DOS environment to boot and run in. Please see this forum thread for more info on how to possibly do this.


Yes, you would need a news reader to post a reply there. You would also need to register with the GRC newsgroups before posting a reply. Please see this page for more info:

I created a USB freeDOS drive and put SR-R11 on it from my ThinkPad, had to charge the battery enough to stay booted. Will try to boot from that USB drive with SR on it.
 
Ran it on my Thinkpad T520, I didn't realize how little it does at this point. Still upset years of SpinRite were lost due to Sqrl. At least I found ONE real use for Sqrl, this Forum... Thanks for the help to get this far.
 
Still upset
Hold your horses there bucko. "Upset" is too strong of a word in my opinion. "Disappointed" I would accept but not "upset". Last I checked Steve is a free man, not your slave. He produced a product, SpinRite 6, got it to completion and sold it "as is" at the time anyone might have made any purchase. You were/are owed nothing more. It's his business to run in any way he sees fit, or not at all.
 
@MarkyMac The current version of SR was created many years ago and still works very well for both HDD's and SSD's (which didn't even exist at the time). To say it does little is completely erroneous. It's doing a huge amount of critical work on the HDD / SSD behind the scenes. If the HDD / SSD is in good shape, there won't be much to see. That's actually a good thing. But, it still will have forced the drive to look at each sector, do its internal analysis of "health", and update its diagnostic tables and possibly rewrite bad but recoverable sectors. This has therapeutic value and can keep the drive from developing bit rot just by the fact that you run the program periodically. I have no hesitation at all in saying that SR is worth the price. Furthermore, where SR really shines is if the data cannot be quite read. It can often recover enough data from the abyss to get an unreadable drive to read again and allow partial or full data recovery. Even after all these years, this is industry leading technology. @Steve is an engineer of the highest caliber that values product quality above deadlines and marketing and PR considerations. He's one developer who stays busy, not a team of 20 programmers. Nobody is perfect, but he really does try to get it right. So, before being TOO critical, please try to understand the product and the developer. If you have questions about SR, you can ask here and maybe someone can answer. (We don't work for @Steve , but are customers and fans in most cases.) If, for some reason, you are dissatisfied with SR, I believe @Steve has a money back guarantee.

May your bits be stable and your interfaces be fast. :cool: Ron

He rakes in so much money on the current SpinRite, so he's really not concerned about customers that were patiently waiting for rabbit, or moose, or squirrel to finish and then go literally nowhere. Thanks for feeling the need to rant about my endeavors to see what SR-R11 does.

SR-R11
 
feeling the need to rant
You do realize that you're using HIS platform to slag him, right?? And I don't know how you know anything about his financial situation... it's certainly not anything he has discussed. One thing I do know about his commitment is that he is totally willing to spend money to buy problematic equipment so he is able to test his code so his users don't have to. Not even Microsoft does that any more. It sucks for you that you think you are owed something when you are not--I suggest you look elsewhere for pity.
 
@MarkyMac bear in mind that R11 is beta software as @DanR mentioned. Therefore it could have bugs in it. Having said that, @Steve is one of the best bug hunters and is very committed to quality. But, there's always some potential for failures in such software. For that matter, there's potential for failures in release software too. I'm sure @Steve will work very hard to expunge the bugs before release. The beta testers help him do that.

I'm sure most people here are willing to help you with issues you have with the beta software if they can. I personally have no Mac knowledge. Trash talking @Steve doesn't endear us to spend extra time on your case. Sure, @Steve is raking in so much money that his company team went from 5-10 or more people (don't know the exact number) in the past to 1-2 people now. Maybe it provides a living and enough to run his one man development shop, but I doubt seriously if he's getting wealthy. I think lots of people don't even know there's a need for such software in the modern era.

@Steve doesn't have lots of time to do tech support here in this forum especially for a product you haven't paid for (I'm assuming). But, I KNOW your statement about him not caring about his customers is erroneous. That's why the rest of us try to help out when we can. And, if you're able to test the beta product and provide feedback, I'm sure he'll appreciate it.

Perhaps, instead of sniping at each other, better results can be obtained by focusing on what SR 6 (current release) can do for you if relevant, on what R11 can do for you if relevant, and how to use them. I'm sure there are those here that will try to help if they can within reason.

May your bits be stable and your interfaces be fast. :cool: Ron

100% correct.

Correct. Steve has been very busy developing SpinRite 6.1, a HUGE task. This task has very recently completed a 6 month phase of rigorous development testing by the dedicated members of the GRC SpinRite Development Newsgroup. Steve is now working on SpinRite 6.1 Beta 1 coding.
what R11 can do for you if relevant
R11 utilizes the latest code for detecting and enumerating drives and then bench-marking them. It also uses and displays the latest GUI screens. It does not. however, "touch" any data.
 
For someone who claims not to care about possibly millions in "lost" Bitcoin, I'm pretty confident abut his financial situation.
