Hi all. I have a similar problem as stated earlier. I bought two EZbook 3 pro V4 and two ADATA M2 SSD (128gb). On one unit the SSD was seen initialised, formatted and working fine. On the other the ssd is not being seen even after swapping SSD’s. What can possibly be the issue or should I consider returning the unit. The ssd in installed properly and tried a clean install of windows. Appreciate any assistance.
