Spinrite 6.1 Rc5.05 500gb HDD Attempt to execute illegal opcode

  • 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.)

Hi, This happened, it is my D: drive, it is admittedly old and has miscellaneous data on it. It was about halfway through first row of dots. I was scrolling through the screens and error occurred.

@Noswal : THANK YOU for the report!

I'm glad that you provided the extra detail that this occurred when you were scrolling through the screens. That gives me a good clue about where to look for the trouble... and maybe the opportunity to recreate it. I've opened an “Issue” for this over in GRC's GitLab so I will pursue it! Thanks again!
 
@Noswal: I just found and fixed a bug I introduced (along with a new feature) back with RC4. The new feature added logging of the number of over-temperature events that occurred on a drive between other log entries while SpinRite is running. That bug messed up SpinRite's screen display code. So I'm wondering whether that drive might have experienced an over temperature event while you were running it? That event would queue up a pending log entry that definitely would mess up SpinRite's code. If you don't recall ever seeing that I'll setup an automatic screen switching test to see whether I can make SpinRite misbehave. But, for what it's worth, we haven't seen in instance of a crash like you've reported before... and the over-temp event would definitely have been a likely cause. Thanks!
 
Hi, I ran SpinRrite again on that drive yesterday, without viewing the other screens, found 3 errors at end of drive.
HWinfo64 records drive maximum at 43C, average 39C. Whatever it was on my drive that caused the error am very glad to have been able to contribute to SpinRite's development.
