Hard Disk Suddenly Disappeared

[ar15]

My PC has 2 physical storage, HDD and SSD. Somehow, i'm having this problem where my hard disk suddenly disappear. When i restart and open BIOS menu, the hard disk doesn't show up. I've tried to reattach the HDD, it showed up but took a long time to boot and i couldn't even open windows explorer. after I tried to restart the PC, the HDD disappeared once more. So, Is my HDD possibly broken? it's actually my laptop's and has been powered on since early 2013

ar15, seems like the drive is faulty. Did you do a clean install on the drive before adding it to your system?

Examine the SMART report in CrystalDiskInfo:

Look for reallocated, pending or uncorrectable sectors.

It could be that the drive is taking too long to come ready, so the BIOS detection process times out. This could be symptomatic of weak heads or bad media.
