Cannot install Helper tool on Big Sur 11.6.2

@numinoos 

In the support file, it shows the volume was created on October 21. So unless you "erased" it, you did not delete it. that is interesting.

Also, do a test run of Disk Drill. Its free to try (You only need to pay if you are actually recovering files). Scan using "all methods" and in about an hour or two max, you should see if it can recover any structure. I will guess it has the same results as R-Studio, but this is a worthwhile test to do.

This is Mark's reply from Aloft Tech Support as regards DiskWarrior: "When a RAID set is deleted/removed, the directory (index of the files and folders) is removed.  DiskWarrior uses the directory information to recover files. DiskWarrior is not a tool for recovering deleted items."

Thus, DiskWarrior is not geared to RAID recovery.

I do not like Disk Drill; I find it too invasive. I have tried it twice at separate intervals and removed it. I will nonetheless give it a try and let you know.

I have known R-Tools Technology for well over 10 years when I was stuck in the Windows world. I feel more comfortable with R-Studio.

Marc has been at Alsoft a long time. But it does not appear to me that you deleted the volume.

What (I believe) he means is if a RAID volume is deleted, Disk Warrior can not put "Humpty Dumpty" together again. On a single disk, sometimes you can.

DW should have been able to get something, but sometimes the damage is more than can be repaired, usually in my experience, the result is "the directory is too damaged to replace" or similar.

I understand with Disk Drill, in the last couple versions, he is trying to make it too many things, rather than focus on recovery, etc. the app should leave monitoring disks, etc to other apps. what ultimately happens is too many apps are calling on SMART that system performance drops.

I tried with Disk Drill as you suggested scanning the volume using "all methods. After 1h30, it retrieved some image files but the file names were not the original filenames contrary to what R-Studio produces.

Besides, after 1h30 minutes, there are 290 Hours remaining !

I think I will stick to R-Studio which will recover the image files in their original file naming reference and hopefully the full folder structure.

I will start the process at later stage on my Mac mini after Monterey 12.2 is released and I reinstall macOS from scratch then SoftRAID 6.2 is installed anew.

I don't want to do it now to avoid hoarding my wife's Mac mini ;-)

I will keep you posted.

Thanks for the feedback on difference in the two. Its nice to have multiple good options.
