  • 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.

Hi,
I have been asked by a friend for recommendations on testing USB flash drives. He has been tasked at work with coming up with software to test a new product they are making. My first and only recommendation was the GRC suite. Spinrite for their design verification and ValiDrive for manufacturing tests.

The issue is, ValiDrive does not lend itself to automated testing (avoiding mouse movers and clickers), as far as I know.

Has it ever been suggested that there be a paid for entreprise version of GRC utilities, that allow for running from the command line and getting the results in a more "automatable" format. I suggest paid for as such functionality would probably be used by people doing "work" and therefore paying for it would be fair.

Thanks

But they're making these flash drives themselves? ValiDrive specifically tests for fake flash devices, I assume that's not an actual issue if they manufacture these themselves? What exactly are they making and what type of testing they need?
 
They are making them from scratch - putting down a flash chip and a controller etc.

Design validation - Testing at temperature extremes, physical shocks, radiated immunity. Spinrite would be great for highlighting errors after these tests. Limited number therefore not concerned with automating these

Manufacturing tests - Has the right chip been put down? Is it fully connected? ValiDrive is written by an expert and produces useful statistics that could highlight outliers.

Controllers are typically accompanied by software from controller manufacturer and these tools would typically have lower level access to the USB flash drives than any other tool. They can for example tell the controller itself to go check the NAND chips for flaws.

Probably not so much at this time. It (SpinRite) relies on system BIOS accessing those drives and purposely limits itself to first 128 or so GB of USB drives.

This type of testing is typically done using purpose written scripts and software, that writes pre-determined patterns to drives accompanied by LBA address + checksums so you can detect stuff like silent corruption due to to name one radiation, or another like LBA address conflicts due to FTL corruption.

I think we should put this in perspective. Steve is still exploring all that's specific to NAND based storage devices. There's numerous science papers devoted to this topic.

ValiDrive, although useful, does 'nothing special': It uses Windows drive/file IO to access drives and simply measures time it takes from issuing a command to completion. It writes 'noise' to some sectors and then sees if it can read the same noise back. Essentially that's it.
