  • SpinRite v6.1 Release #3
    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.)

i have a metaphorical "pile o' drives used to save all my stuffs on.
8 attached to the Sata ports on my ASUS Crosshair VIII Hero and 2 more attached to a PCIe sata adapter.
I'm actually glad it picked up the PCIe ones, but i do have an issue with that controller with windows, if a drive has issues reading it stalls windows, will have to test it out with SR6.1 once released.

1st it was a pain to boot, after finding the correct setting in the bios the bios created 2 entries in the boot, 1 was UEFI the other was just usb. the bios defaulted to the UEFI and then failed to boot even gave a D9 post code. once the just USB was selected it booted right up. something to note for some bios-es.

2nd here is the simple results

3rd, somethings i noticed
my 2 3tb drives (85 and 86) have a weird dip in performance about every 6 chunks

my 2 SSDs (88 and 89) have like 2 modes. 500 and 270
88 - is probably my boot ssd
89 - is probably my Steam SSD

the 8TB Drives (87 an 8A) are new as of 2 months ago.
only my SSDs work with SpinRite 6 so the 2, 3 and 8TB will not let me run them currently because of GPT and i'm glad that this is picking them up.


1 adding Serial Number to the log file so i can tell my drives apart of which is having errors
2 give the option for CSV export although it is constant enough that loading it in Notepad++ and some Search and replace was able to get it formatted fairly easily.

5th, i made the larger file with the "-1" option
it took some time, but i converted the thing to a CSV and imported in to Libre office. here are my fancy charts i created.
