After an unexpected restart of an ISCSI device the ReFS volume became unreadable (no problem to the NTFS). It appears as RAW partition and clicking on it the "the volume repair was not successful".
I browsed on internet without finding any solution.
Therefore, before reformatting the volume (NTFS this time...) and restore data from tapes, I was wondering if there is a way (even experimental) to try to rebuild the partition table or at least access to the disk.
The volume was used to archive millions of files (25tb) in a complex tree structure, so using recovery software is not an options (unless there is a sw that is also able to rebuild the the directories structure).
Thanks in advance,
