Hey there, gtrainer.
Basically, it sounds like your drive might be in a pretty bad situation. If you have data which you need to recover, I'd recommend that you try it with a different computer, either externally (via a SATA to USB adapter, external enclosure, or a docking station) or internally, to see if the drive is recognized. If you're still having issues, you could try it with Ubuntu Live USB/DVD, to see if you're able access the files and recover them. Another option would be data recovery software:

On the other hand, if you don't need any of the data, you could still connect it to a different computer and try running some tests on it with an HDD/SSD diagnostic tool if it's recognized, to see what's the situation.
Hope that helps. Please let me know how everything goes.
