The hard drive became unallocated – how to fix

The drive becomes unallocated or uninitialized if it has neither a partition nor a volume; as a consequence, Windows Explorer doesn't display such a disk. Unallocated or "not initialized" issue may happen with any storage device, be it a hard drive, USB flash drive or memory card, as a result of accidental incorrect user actions, as well as due to the circumstances independent of the user.

Usually, you do not see an unallocated drive in Windows Explorer. To see the drive you need to go to the Disk Management (press WinKey + R on the keyboard, type diskmgmt.msc and then press Enter). Disk Management displays the drive as having black unllalocated area.
