Hello everyone,
I’m experiencing an inconsistent issue with both of my NVME drive adapters on my 2019 Mac Pro running Monterey 12.6. The drives intermittently fail to mount, and I find myself having to restart the machine repeatedly to get them recognized. When I try to mount the drives manually, I encounter an ‘Invalid Disk’ error, yet Disk Utility shows no issues or failures with the drives. I’ve also recently returned the Sonnet Flex J3i for a replacement; the RAID setup was failing to mount after each restart via the USB-connected SSD.
I’m uncertain if this problem is related. Additionally, I have upgraded my MPX module to include two RX 6900 XTs. For context, I have the following setup:
1. Sonnet’s M.2 4×4 PCIe card with four Samsung 980 Pro 2TB drives configured in an 8TB HFS+ RAID0.
2. OWC Accelsior 4M2 PCIe card with four Sabrent 1TB drives, creating a 3TB HFS+ RAID0 and a separate 1TB Windows installation. Interestingly, the 1TB Windows SSD consistently mounts without issue, while only the 3TB and 8TB RAID drives present problems. I have attached my system report to provide any additional insights that may assist in diagnosing the issue.
Any advice or suggestions you might have would be greatly appreciated! Thank you in advance for your help!
