ReFS had many problems though.[1] Are they better now? [1] https://www.reddit.com/r/DataHoarder/comments/iow60w/testing_windows_refs_data_integrity_bit_rot/ ht

  I tried it a few months ago and ReFS ate my data. No indication of why in event logs or SMART data. It had IsPowerProtected set because I have a UPS and I had a unclean restart, I would expect it to lose data, but not to corrupt the filesystem metadata. I had a backup of the data but wanted some recent changes. Refsutil (the official Microsoft tool) didn't help because it has not been updated for the newest ReFS version. I couldn't read most files because I had integrity enable and files failed the check. Hetman's Data Recovery was able to recover most of the data. In later testing I found out that IsPowerProtected is just very unsafe. I have since put some time into testing and sometimes fixing https://github.com/openzfsonwindows/openzfs https://github.com/openzfsonwindows/openzfs , it is not ready for use yet, but it is making great progress.
