I have access to the C drive, but no longer see the D drive in either Device Manager nor when I start with BIOS.

Tried booting up in SafeMode, but still not visible.

it may be defective
This type of computer is quite fragile, it may be necessary to go to a specialist
it would be necessary to open, check, remove the hard drive
possibly, try to connect it in usb
If it works recover the data
Format it and put it back in the computer
if still not working then replace it
