[yaseenkhan]

Thanks for stopping.
I have hp431 laptop. Previous i was using Windows 8.1 on my hdd,then i got ssd (bx500 crucial). I have done Windows 10 on that ssd. When i boot from hdd the ssd whould show as a regular disk but if I boot up from ssd the hdd disappear even from disk management.
I want to use the hdd as an external drive is there any solution for this?
