    Hello,

    I have performed several stress-tests of new ReFS and discovered failure in automated correction mechanism, what will result in something like this:

    Recovery4_Full.jpg

    Many kinds of errors, what can be nicely corrected at NTFS by:
    Code:
    chkdsk <drive-letter:> /f
    CANNOT be corrected by user at all, when ReFS is applied.

    Do NOT use ReFS unless for testing, it is not safe.

    I can only imagine there is a new utility or CMD option in Windows swiss army knife of utilities somewhere.

    @moderate, can you give any more detail of how you stressed-test ReFS? Is it something which anyone like I can reproduce?

    I haven't had a problem yet, but that doesn't mean I won't, of course. The details of my setup is that I have an eight-drive 4.12TB Storage Spaces Pool with Parity which is formatted with ReFS (under Windows 8 MCE x64).

    I was pretty desperate for an easy and cheap backup/redundancy solution as I had most of 4 1TB hard drives filled up, and I had them configured in RAID 0 at the time. I didn't have enough realistic hard drive space to back things up to. I had to begin with 13-drive Storage Spaces pool with Parity using every little hard drive I could connect. At least half of the hard drives were connected via USB3.0 and USB2.0. Then I had to copy my files from my 4 1TB RAID0 to the Storage Spaces pool. I then added my 4 original 1TB hard drives (now not in RAID) to the pool, and then I would remove one hard drive from the pool at a time, usually the smallest ones first. Each time, Storage Spaces rebuilt the missing the data, and once it was done I would remove yet another drive until I'm left with the now manageable largest eight hard drives that I have.

    Hopefully, using Storage Spaces with Parity in conjunction with ReFS, it is able to make up for any reproducible ReFS problems until a better solution and/or a newer release of ReFS comes along.

    The same thing happed to me today. I changed my RAM sticks and my PC crashed shortly after boot. ReFS wasn't resilient enough to handle this. chkdsk found no problem on the NTFS partitions.

    Thanks moderate,

    especially in corporate enviroments I would not recommend using ReFS.
    Every data recovery company will tell you NOT to use chkdsk if you want to get your data back.
    And that's what I think even about a 'self-healing' feature ;) ...
    as for example chkdsk at autorun caused a fatal data loss often and left clients with tiny chopped
    fragments of the most important data(bases).
