When an SSD isn’t detected, try:
1. Cables/slots
- Verify proper SATA/NVMe seating.
- Test other ports/cables.
- Use a USB enclosure to cross-check externally.
2. BIOS/UEFI
- Ensure the SSD is visible in firmware.
- Check AHCI/NVMe modes.
- Temporarily disable Secure/Fast Boot if necessary.
3. Drivers/firmware
- Update motherboard and SSD firmware.
- Refresh storage drivers (Windows Device Manager).
- On Linux, check with `lsblk` / `fdisk -l`.
4. Second system test
If it works elsewhere, the origin system is suspect.
5. Hardware fault & recovery
If still invisible, suspect worn NAND, controller failure, or electronics damage. Use a professional lab to avoid data loss.
