  • 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.

Thanks for posting those! An impressive improvement! :)

Is the first drive SATA II by any chance? Interesting that it seems to have a speed cap at around 273? Or do you reckon that’s just the maximum drive speed on the older model?
 
@lovecakeboy @bghite it should say above the benchmark table if a SATA3 Capable drive is connected to a slower interface. If you want to rerun the benchmark hit the escape key and run

RS.exe /ident

This will specify the drive and interface capabilities.
