There are no tools to repair or recover a ReFS filesystem. Third party tools are dependent on reverse engineering the system and (as of 2014) few of these exist.[21]
Windows Store cannot install apps on a ReFS volume.[22]
If integrity streams are enabled and there is no data redundancy available (disk-level parity or file-level backup), ReFS will render an entire file unrecoverable by any means if even a single bit in the file is found to be incorrect.
