Hello,
I reconnected an enclosure setup w/ an older verion of SoftRAID to my newer MBP and I get the SoftRAID Driver Error message.
The four disks are listed in DiskUtil but the 4TB partition ( `FA709C7E-65B1-4593-BFD5-E71D61DE9B02` ) doesn't mount.

Was there a mounted volume on these disks? SoftRAID is not seeing the actual volume, so there is partition map damage. Its confusing as the disks are reading 0 power on hours, this is either a bug, result of the partition map damage, or these are new drives.
Let me know.
The 4TB volume was indeed mountable.
Do you have it backed up? We can likely recover it, but it may take time to get to it.
Yes. It was created a while back so I really just need to check what's on there in case there is something that I missed.
I applied the recovery file and rebooted. It recovered the array, but it fails to mount and ends up w/ an `unmounted` status. I emailed back an new support bundle as well as a screenshot.
I do not know who got your case, so attach a support file here.
