Disks not mounting after initialize "The disk you attached was not readable by this computer"
I've just bought a Thunderbay 4 and installed 4 Samsung 4gb SSDs with the intention of running a RAID5 on them.
I went through the looong Certify-process of about 35hours with no errors.
After that I selected all four drives and selected initialize. The minute they were intialized my mac announced "The disk you attached was not readable by this computer" four times.. Any idea how i proceed from there?
I'm running all this on a MacBook Pro M1 Max with Monterey ..
Up till now i've restarted my computer. I've re-initialized the drives (with the same result) .. I tried setting up the RAID 5 drive, hoping that it was because it wasn't fully set up, that it wouldn't read the drives.
The drives show up on my disk utility - i'm assuming it's a SoftRaid issue?
I'd greatly appreciate any help you guys can give..
Did you do this?
Select reduced security and enable this:
Select the “Allow user management of kernel extensions from identified developers” checkbox to allow installation of software that uses legacy kernel extensions.
When you did the driver update, did you go to System Preferences / Security to "Allow" OWC as an identified developer?
After enabling third party extensions, reinstall the SoftRAID driver, and go to System Preferences / Security to "Allow" OWC as an identified developer
Hi, I'm having kind of the same issue. 2013 iMac w/BigSur. I had a Thunderbay4 with 4 10TB WD drives in Raid 5 config. Setup went perfectly. Upgraded to a Thunderbay8 and bought 4 more WD 10TB drives. All 8 are Red Plus drives. When I installed all 8 drives into the TB8 and started up, SoftRaid6.3 still saw the original volume on the first 4 drives. I certified the 4 new drives and all passed. I deleted the original volume and initialized all 8 drives in softraid and after that I got 8 "The disk you attached was not readable by this computer" MacOS messages. I clicked ignore on all of them and tried to create a new volume and it gave me a generic unable to create volume message. The new volume shows up in the SoftRAID utility but is unmounted and won't mount. SoftRAID log says it is an error 125. SoftRAID has access to all disks checked in security preferences. ?
Aug 22 1546 - SoftRAID Application: The volume create command for volume "Raid5" failed with an error (error number = 125).
The SoftRAID driver is still blocked from loading by macOS security.
Did you "allow" OWC, as an identified developer when you installed the driver? Try "reinstall SoftRAID driver" and go to System Preferences/Security before restarting to enable the driver to load.
Yes thank you, that was it 🤦🏻♂️ I checked the Privacy tab in security to make sure Softraid had access to all disks but I overlooked granting it access in the General tab.
I am having the same problem as the others above. I have checked the Security section and ensured that OWC was not blocked. However I now get a message stating "rebuilding, waiting for mount" and on the disk itself, "data and parity disk - out of sync". There appears to be no activity on the new disk?
Sorry, I tried to edit my post but it hadn’t been approved by the moderator.
I reinstalled the driver, and restarted my machine and it appears all is well as it is going through the rebuilding of the disc
