Question old hdd shows up in bios, but not in disk management

Jul 8, 2020
I have an old system (dell optiplex 3010) as a little budget gaming pc until I can upgrade to something better, I just now plugged in my old laptop hard drive (2.5 inch drive) and it shows up in the bios, yet when i boot into windows 10 and try to format it, nothing shows up in disk management. Some things to note, it came from a Lenovo laptop. I'm not sure if that has anything to do with it, and also it already has a copy of windows 10 on it.

The possible causes for such an issue can be an incompatible file system, missing drive letter, disk driver issues, damaged partition issues on the hard drive. In a worst-case, the drive itself is failing.

You can try below fixes to resolve the issue:

  1. Initialize the drive or drive partition
  2. Change/Assign drive letter
  3. Update Disk drivers
  4. Enable drive in BIOS


The drive may be a secure model and is waiting to be unlocked by the bios. Which exact model is it?
If you still have the old laptop you can unlock it and unencrypt it in that, if that is the cause.
