Hard disks

Why does the computer not see the hard drive, although it is in bIOS and device manager says that it is working fine

Answer 1

most likely because there is not a single partition on the disk formatted in any of the file systems supported by your OS.

Answer 2

It must be activated, before work, Windows usually offers itself, but the user does not see it, although occasionally she herself forgets to offer it.
Therefore, just go to "Disk Management", you will be prompted to activate the disk. If not, activate it yourself.
