If you need additional recovery, you would have to send the disks here, we can do basic recoveries. I do not expect more than what we can do remotely.

ok thanks for looking into it. Yes please let me know the cost to fix. Will I need to send the drives off or can it be done remotely?

Not good news. this issue was caused by a known bug in USB 3 with Mac's and many USB enclosures. this can damage bot volumes and in SoftRAID's case, the Status partitions, (which is why the volumes are missing disks)

We have the ability to fix this, but it there would be a significant fee. I can discuss this with you off line if you want.

Hi, I was wondering if there was any other suggestions for this? 

 

Thanks

I am meeting with engineering today to see if we can work on this.

Let me ask engineering on Monday, when we can try to take a look at this and give you options.

 

thanks!

Both those volumes were in the process of cloud backup and were about half way done (my bad for not having second hard backup, was hoping the raid 5 would offer me some reliable redundancy). So if there is anything we can try to salvage I would really appreciate any further assistance. I can be available for walkthrough on the phone if easier. 

Maybe there is some terminal commands or something in disk utility I can try to sort out the partition maps, I wouldn't know what to try or start with though.

FYI: SoftRAID creates a "container" for your volume. It does nto know what is inside the volume, nor control what gets written to it. Its more of a traffic cop, sending traffic into the volume. It is up to macOS to manage that data. So a validate confirms the volume is OK, but that does not analyse or repair any files inside the volume container.

What appears to be the case is the partition maps on the stripe are damaged on one disk. Archive appears to have damage to the volume header, but SoftRAID cannot read enough of the volume header intelligibly to create a mount point for the volume. So notice it does not have mount point (disk identifier)

This could have been caused by a USB glitch, cable glitch or enclosure issue, I really do not know. When volumes are mounted, nothing should have access to those parts of the disk.

We may be able to rescue the RAID 0 for you, I would have to ask engineering. the archive may be more difficult, I am not sure. Backups would be the better approach if you can restore from backup on that.

There may have been a crash/reboot that I missed just before but I am unsure, The archive volume isn't mounting but softraid shows 4 disks with no errors, so I am a bit confused by that. I had actually just validated the archive volume not long before this which came back with no errors. 

The stripe volume was in the process of backup to cloud :(
