  • 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.)

Go ahead - just try to guess which drive I'm using for my boot disk

I'd been noticing odd occasions where my machine just seems to take a quick siesta. I'd guess the culprit might've been found?

So I'm thinking that now would be a good time to go get a replacement SSD and then just set this one aside so that when Spinrite comes out see what sort of changes take place.

@ggerke : (I put your results in a CODE block so that all of the columns would line up.)

You should run the benchmark with one of the detailed dump command-line options, like /1, or perhaps even /4. That will break down the summary results into a transfer-by-transfer detail. :)

So I tried rerunning on the various levels along with running it without options and got the following. With the changes in results for that 240GB SSD would that be an indication of the disk slowly losing it's mind?

I tried running Spinrite to see what level 1 would do but I got stuck on the discovering storage devices screen.

If you try running RS.exe with the "/1" switch you will get a more detailed report. This may show that there is one very slow spot which is dragging the averages down. We have also seen an effect where a disk is mainly empty, and it is suspected that some drives, knowing that the, say, 75% area is empty, respond much quicker with an empty block without doing an actual read.
