- You have a computer with an M.2 disk or NVMe drive in RAID mode.
- When booting the computer with Acronis Linux-based bootable media the disk is not detected.
Acronis Linux-based bootable media cannot detect some M.2 and NVMe drives in RAID mode due to a Linux kernel limitation.
Use WinPE-based bootable media. See: How to create a WinPE-based bootable media.
In kernel log, you can find this warning:
user.warn kernel: ahci 0000:00:17.0: Found 2 remapped NVMe devices.
user.warn kernel: ahci 0000:00:17.0: Switch your BIOS from RAID to AHCI mode to use them.
While switching from RAID to AHCI will solve the initial problem and allow Acronis Linux-based bootable media to detect M.2/NVME drives (in AHCI mode), please be aware that switching from RAID to AHCI mode will disable RAID and might cause OS boot failures. You need to prepare your machine for this action, please contact your hardware manufacturer with this inquiry.
