I recently put my laptop in sleep mode and when I woke it up there was just a black screen. Made a hard restart and now my OS HDD is not detected anymore in BIOS. I tried putting it into my second HDD slot of the laptop, still not detected. Tried putting another HDD into the main HDD slot, this one got detected so I assume it is not an issue of the connection port. I then also tried the same with connecting the HDD to another laptop via an external drive adapter - again for the main HDD nothing was detected, my secondary HDD was working fine there as well.

Obviously something is not working anymore with my hard disk but as it does not even show up in BIOS or via external disk adapter, is there anything I could still do or try out or a way to safe my data?

Since it is not even being detected in an external adapter then it appears to be a hardware issue and to recover the data the best course of action would be to send it to a company specializing in repair and recovery of data. This service is usually expensive.
