Intel SSD 335 not recognized

Hello,

I use a SSD drive on which I installed Windows 7. Until then, I had no problem, no bug, no crash. The system was very stable.My one and a half year old girl played with the power button of the case by pressing it several times and since the SSD is no longer recognized in the bios.My PC does not boot.

I tested several SATA cables and power connectors, change the SATA port on the motherboard, unplug the disk for more than 10 min then reconnect and let the PC run more than 20 min several times without success.I installed an old functional HDD with a version of Windows 7 and again the disk is not detected by Win 7.

I'm a little afraid that the disk is HS. What do you think ?Would you have an idea how to recover the disk and / or files?

Thanks in advance.
