So I was wondering why my Hard Drive will not show up on 'My Computer' but my SSD did. Later I realized that it has not been partitioned yet. So I went into Disk Management and where is said unallocated (Disk 1 I believe) I right clicked and hit partition. It's a 2TB hard drive so it should take a while. I left my computer overnight because it was already 2am and it was taking more than an hour. Stupid me, I forgot to turn the sleep mode off. So during the night, the computer went to sleep mode while it was partitioning the hard drive. This morning I turn on the computer and it said it failed to partition because the computer went to sleep mode. Now my hard drive won't show up in Disk Management anymore. I checked the BIOS and it's picking up the hard drive. I just can't find it once I start it. Does anyone know how I can get it back to Disk Management? I wanted to partition the Hard Drive into 2 parts. an E:\ drive and G:\ drive.
