Macbook pro doesn't recognize internal SSD
Hello, I need your help. For the past couple of days or so, my early 2015 macbook pro (Model Identifier: MacBookPro12.1) no longer recognizes the internal 128 GB SSD and a folder with a blinking question mark is shown when I turn it on. I also tried booting the pc in macOS Recovery mode but even from there unfortunately the boot disk is not seen. Also doing diskutil list from terminal there are a number of containers and volumes but they do not match the capacity of my internal SSD. Only the boot sound can be heard, and this worries me quite a bit since I have important data and would like to access the contents of the storage. Unfortunately, I do not have a backup of this disk and would like to rule out the worst and that is that the SSD has failed at the hardware level. Any suggestions or ideas? The version of the operating system is expected to be macOS High Sierra. Please help me
