Idea - Incorporate DFSee for partition, file system and file recovery in SR 7

  • 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.

DFSee is free (formerly paid) software which has functionality to examine and fix partitions and file systems, with file and partition recovery and cloning facilities. The author has sold this commercially for about 20 years, but he's announced that he's retiring and has made the binary free. He has stated that he plans to open source the program in the near future. Steve, this seems like a similar situation to RTOS, with an author who has done all he can with the code.

Website here:
DFSee Homepage

The program is written in C, and started out on OS/2 but is now a cross-platform text mode UI program with the same capabilities on DOS, Windows, OS/2, Mac, and Linux. The author also has already open-sourced the cross-platform text menuing system he wrote for DFSee.

It understands both MBR and GPT partitioned disks, and understands the following filesystems:
MS and Windows: FAT12, FAT16, FAT32, VFAT, ExFAT, NTFS
Linux: Ext2, Ext3, Ext4, Reiser

@Steve, you'd obviously have to see what sort of terms this author would want, but I think you'd be shaving 6 to 12 months of development time off of SR 7, assuming you want to incorporate this type of functionality as you've stated. Maybe take a look once you start thinking about the SR 7 feature set.
A future SpinRite will definitely add cloning, file level and filesystem recovery. If he were to open source his code I would be stupid not to take advantage of it as a reference point. Not knowing anything about what he's done, I have no idea how much of it might be useful. The good news is that there are now a great many existing open source projects which support those file systems and documentation is far more available that it once was. So I'll definitely be open to anything that might help to reduce development time. Thanks for the pointer. If you happen to become aware of his source being posted, I'd be happy to have you bring that to my attention! (y)
Hi Steve,

Clearly if SR 7.0 is filing system aware then it can concentrate DynaStat on the areas that actually contain data rather than blank or empty storage.

For many if not most users this would result in a radial improvement in performance if data recovery is the desired goal.

For actual data recovery I still use R-Tools R-Studio, which I believe you are familiar with.

Are you likely to produce something with similar capabilities within SR 7.0?

Kind Regards

In a word: Yes. We'll be getting there incrementally, first duplicating what we have today. But that will be just the start. My absolute plan is for SpinRite to evolve past where it's always been, which has been an "in place" drive maintenance and data recovery tool (which has helped and recovered the data for so many hundreds of thousands of people through the years), into a tool that will be able to remove recovered data from troubled drives to another media.

Back when SpinRite was created, 10 megabytes of storage cost around $5,000 USD and few people had more than a single mass storage device. Those times have obviously changed. My point is that originally, there was no where else to place recovered data. Today that's not a problem. So I'm extremely excited about where we're going to take SpinRite in the future... and it will definitely be into file system aware recovery, image cloning, and so forth. (y)
