  • 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.

I have a Dell XPS desktop that has 4 built-in SD card readers on the top front. I see it in Windows, and Valide Drive sees and says it's OK.
When I boot my Spinrite USB flash drive, Spinrite doesn't see it.
I thought those SD card readers were USB. Should I get a USB card reader?

Thanks, Mark

SD cards (at the hardware level) are quite a mess. And since there's never been any standardization at the PCI bus register level there's nothing for SpinRite to support. IF a machine's BIOS supports its own SD cards then SpinRite should, too. But since your SD card is not showing up, it's likely that your machine's hardware needs support from a machine-specific driver... which I doubt SpinRite will ever offer.

So, yes, the right solution would be to use an SD card to USB adapter to make those SD cards visible. During SpinRite's testing we fussed around with SD card adapters and we generally had success. (y)
Did you insert the SD card before booting into FreeDOS? That's required for SpinRite to have any chance of seeing it.
