Odd SpinRite Error

  • 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.)

Hoping Steve finds this helpful, more than anything. I Tried scanning a friend's old Win7 hard drive recently. It's a Samsung, 1TB, several partitions. I tried in Modes 5, 4, then 2, all producing this error in the exact same spot. First two partitions are extremely small, flew past those, but the instant it got to that 3rd partition...two beeps, indicating it's starting to find an issue...pause...DynaStat kicks in, started to run, then bam. This screen. Every time.

This isn't the original machine the drive was in, I'm currently using a very lightweight dedicated Atom powered box I found in the trash that I use for SpinRite. I've SpinRited several drives in this box, including some old slow 2TB Greens that took over 250 hours each. SpinRite has been helping me for over a decade. Which is why this bugged me enough to register and post it here.

I'm so confused at why this Division Overflow Error kept happening that I said "screw it, lemme see if it will wipe." I fire up DBAN, started a default wipe. DBAN got to about 30% before I wanted to try SpinRite again, because that division Overflow was happening in somewhere under 5%.

Now SpinRite is churning along...okay? You can see the remaining MB stutter briefly about every 2 seconds. It's not consistent, you know, like on a good drive.

TLDR it would give me this error within 30 seconds of starting the scan before I partially wiped the drive, now it's been running for 45 minutes dependably after I partially wiped it.

Maybe DBAN forced it to noticed a sector that killed SpinRite? After dozens and dozens of drives scanned, the one thing I know is it's really hard to kill SpinRite. It's hurting my brain, hopefully Steve can make sense of what his baby is doing from my rambling and make it not do this weird thing later.

Also, apparently the hugely insane image size of 3.21 MB of the default photo from my cellphone camera is beyond the limits of this website...in 2022. That's kinda annoying, but par for the course I guess.

The division overflow error is a known error with SpinRite 6.0. Steve is aware of it.

SpinRite 6.1 will not have this error condition. :)

No need to hurt your brain over this one! :unsure:

Yes, this is probably because SpinRite has an old world view of the partition table and your disk has a new world presentation. Perhaps your disk was partitioned with GPT instead of MBR?
 
doesn't sound partition table related

Well you're free to have your opinion of course, but when the OP said:

I assumed it was something related to the start of the drive/process, and guess what is at the start of the drive. I believe SpinRite attempts to make sense of the partition and file system so it could attempt to write logs into it if that option were enabled. (Not being the author, I am just guess here, as are you, so I was just making an assumption about what would make one drive fail and not all drives fail, and what would be "fixed" by DBAN.)
