I've been using Storage spaces for many years. I have one large 50TB mirrored pool consisting of many drives across many different enclosures.
I recently lost all access to the pool - it shows up in disk manager as RAW file system. The drive letter still shows in explorer but it is unable to access any files. This happened after a reboot.
I ran this:
"refsutil salvage -D s: c:\refs -v -x":
ReFS version: 1.2
Boot sector checked.
Error: No valid superblock!
Error: Command failed.
Error: A data integrity checksum error occurred. Data in the file stream is corrupt.
I then tried:
"refsutil salvage -QS s: c:\refs -v -x"
ReFS version: 1.2
Boot sector checked.
Cluster Size: 65536 (0x10000).
Cluster Count: 838857728 (0x31fff400).
Error: Command failed.
Error: {Corrupt Disk}
The file system structure on the disk is corrupt and unusable.
I looked in eventviewer and found entries "The file system detected a checksum error and was not able to correct it.", and "Volume S: is formatted as ReFS but ReFS is unable to mount it; ReFS encountered status The volume repair was not successful."
Is there anyway to recover the data?

Hi,
For the data recovery issue, I suggest you open a ticket to MS directly. Data Recovery is out of our forum support range.

Thanks for your understanding, if you have any question, please feel free to let me know.
Best Regards,
Daniel
