Is the Thunderbay acting normally now? the drives show up reliably? Next is figure out if this was a hardware issue, (cable for example).
If the volume is working, either backup/restore, or run Disk Warrior on it, so you know the volume and directory is OK.
Let me know what the status is on everything, otherwise I really don't know what to recommend.
The drive is working fine. We've backed it up. It's softraid that won't launch.
Many thanks --
Yes, that's right. The question is why no version 6 will launch. Not 6.1, 6.2 or 6.3. They all show the main window for an instant and then close without a trace. That is the problem.
Monterey should work with 6.3. If you run in terminal.app, sudo softraidtool uninstall
do you get command unknown, or does it do something? If it does, restart and run 6.3 again.
