The biggest failing with Disk Warrior is how slow the preview directory is. (5MB/s amazingly slow)

Sometimes a clean install can help it recover.

Disk Drill was one of the two fastest recovery apps.

One thing I have seen with using both in serious situations is with projects like Final Cut Pro, Disk Drill recovers much smaller files than Disk Warrior's preview. So it is worth leaving the preview up and when you recover with Disk Drill do directory file size comparisons and if you see discrepancy, use Disk Warriors' preview to get a better version of files/directories. But then you are minimizing the time recovering with the Disk Warrior preview.

@softraid-support Forgot to mention, I've tried to repair the directory via Diskwarrior but it says the directory is too severely damaged to repair.

@softraid-support I don't believe I did that, but can't say for sure. I'm using Diskwarrior's preview feature to copy the files off but it's very slow. I'll check out Disk Drill.

I also see a second problem. There is a second volume shown in SoftRAID, same size. I think it is an overlayer from your SoftRAID volume.

Did you perchance erase your volume with Disk Utility in the past? It almost looks like you have a volume inside the volume. this was a bug in an older version of macOS.

It may be wise to do a backup, erase your volume with SoftRAID and copy the data back.

@bcroslin

The mounting problem is a different issue. the directory is damaged.

Do you have access to Disk Warrior? It is the only app I know of that can repair the volume header/directory.

Otherwise, you need to "recover" your volume's data using Disk Drill (probably the best of the data recovery apps)

I generated the report via Softraid and you should have received it from ***@mac.com

@bcroslin

This is an upgrade cycle, however, your volume should still mount.

We now have SoftRAID Lite, which is RAID 0 and 1 only. ($49) that is another option.

If your volume is not mounting, I need to see a SoftRAID Tech Support file. Please save and attach one.

and BTW, I have a Wiebtech Hard RAID that I've been using for 5+ years maintaining 20 years worth of images with zero issues. Everything (OWC Quad included) is plugged into a UPC and I've observed best practices in maintaining all of these drives. Please help me out.
