How to resolve SSD shows 0 bytes in diskpart?

Yesterday I encountered a problem with my laptop (Lenovo Ideapad 330) equipped with an SSD hard drive (240GB) installed in a caddy (instead of the DVD drive) and a 2TO HDD disc: First the screen showed me this error: "the application or system could not be loaded because a required file is missing or contains errors File: \Windows\system32\winload.exe Error code: 0xc000000e" I tried to replug the SDD, then I tried to see if the volume exists from the windows installed on the HDD disuqe, but I see nothing in the disk manager. I booted the pc by a USB key and I tried to see the volume in diskpart: finally the volume exists but in 0 byte. I tried to format it, create a partition (primary partition) but nothing happens except the error messages, what can I do please?
