DNS Benchmark v2 is Finished and Available! Guest:
That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

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.

Respectfully disagree.
Level 5 writes all areas of the drive two times, first inverted and then back to normal. PLUS an initial write for any area with data recovery required.
I cannot see any advantage over a level 3/4 scan which does much less writing. Why needlessly stress solid state media (flash, SSD, NVMe) with no advantage to be achieved?
Correct! And it's a HDD. Level 5 is quite appropriate for that.
Level 5 was developed for spinning hard drives, long before solid state media came into being.
Spinning hard drive technology and solid state drive technology are two different things.
The fact that modern solid state media technology may be more tolerant of Level 5 stressing is not the point.
The point I am attempting to make is that level 5 provides no advantage over a level 3 or 4 scan for solid state media, in exchange for the extra stressing that level 5 does..
