  • Announcing “BootAble” – GRC's New Boot-Testing Freeware
    Please see the BootAble page at GRC for the whole story.
  • 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.

This is a Win 7 Pro machine that was my every day machine from June 2018 thru June 2021, with light use before that for 2-3 years. It no longer connects to the internet - those days are over for this machine. But it still serves me - as an archive for my personal data and as a gaming machine.

Periodic ReadSpeed runs were showing the performance slowly and steadily degrading over time (and especially the last year). I concluded that I should not wait for SpinRite 6.1. :)

ReadSpeed run today 02-05-2022 before SpinRite-ing

Code:
Driv Size  Drive Identity     Location:    0      25%     50%     75%     100
---- ----- ---------------------------- ------- ------- ------- ------- -------
81  250GB Samsung SSD 840 Series         48.9    60.8    64.7   175.6   273.9

Then I ran SpinRite 6.0 at Level 3. And then a ReadSpeed run after the SpinRite L3 scan:

Code:
Driv Size  Drive Identity     Location:    0      25%     50%     75%     100
---- ----- ---------------------------- ------- ------- ------- ------- -------
81  250GB Samsung SSD 840 Series        274.0   273.9   273.9   273.9   273.9

Wow! What a difference. Note: This SSD is a SATA III device running on a SATA II controller, which is all this machine has.

It took SR 6.0 a bit over 4.5 hrs to do the L3 scan. I expect SR 6.1 will be a tad faster. :)

Yup, start up, run performance, and shut down are all faster. Not by enormous amounts, but very definitely noticeable.
