Disk for SoftRaid Volume has disappeared

bPhrea · 2024-12-01T01:11:55Z

Been using SoftRaid XT for some time without issue, currently on 7.5. On a Mac Mini, osx Monterey 12.7.6, running a ThunderBay 6 on RAID 5 over Thunderbolt. Friday evening I was switching my monitor Thunderbolt cable from a work laptop back to my Mini, and I must have nudged the Thunderbolt cable that connects the ThunderBay 6 as the time from the log below matches up. The Mini’s system had been sleeping for quite some time and did not respond, stayed in it’s sleep state. When waking the Mini later that evening I got a warning from SoftRaid that “Disk for SoftRaid Volume has disappeared”. The Raid volume was not on my desktop and upon opening the SoftRaid application, none of the disks nor the volume appeared. After restarting and trying a new Thunderbolt cable, none of the disks nor the volume appear in SoftRaid, nor in Disk First Aid. Any help or advice would be appreciated, I’m pretty experienced on a Mac but have only limited experience with Raid and haven’t yet been through a rebuild process.

Hey can I ask one more set of questions? If I'm unable to resolve the hardware issue, what options do I have for recovering the data on my volume from the 6x drives?

e.g. If I purchased a competitor's second-hand 6-bay enclosure, would the SoftRAID interface be able to access it?

Could I image each of the 6 drives locally and then mount them in a way that SoftRAID would recognise the volume?

Or would I have to go to one of those exorbitant data recovery place for them to combine and then dump onto something else?

SoftRAID is independent of bus or enclosure. Any JBOD enclosure will work. You can split enclosures, such as a Thunderbay 4 drive, plus a OWC dual dock (2 drives) over USB, and the volume is mountable. It does not matter. You could even connect to a Windows machine with SoftRAID. Everything about the disks and the volume is on the disks.

If you connect some other way and the volume does NOT mount, check if there is a disk identifier. (volumes tile). this tells you SoftRAID is presenting the volume to macOS to mount, but the directory is damaged. If this is HFS, then Disk Warrior can repair the directory almost all the time.

Also, the recovery apps Disk Drill, and R-Studio both work with SoftRAID volumes.

So there is almost never a need to use an expensive data recovery service just because the disks are in SoftRAID format.
