Since it is absent from Disk Management, first check whether Windows sees the physical disk at all. Open Terminal as administrator, run diskpart, then rescan and list disk. If it appears there, exit DiskPart, reopen Disk Management, and check whether it is Offline or Unallocated. Bring an offline disk online. Initialize it as GPT and create a volume only if it is a new/empty drive—initializing or formatting a disk that contains needed data can make recovery harder.

 

If it does not appear in list disk, open Device Manager and inspect both Disk drives and Storage controllers for an error, then use Action > Scan for hardware changes. Install the current chipset/storage/NVMe or Intel RST/VMD driver from the PC or motherboard manufacturer.

 

Also check whether BIOS storage mode was changed between AHCI, RAID, or VMD. Do not toggle that blindly, because Windows may stop booting. If drivers look correct, test another slot/cable or the SSD in another PC; that separates a Windows/controller issue from a faulty drive.
