AC1504 My hard disk is not recognized in Windows Explorer

When you have placed a new hard drive into your external casing, it is normal that the hard drive is not yet recognized by Windows explorer

Windows works with logical volumes, that must be created. The drive must be partitioned and formatted. 

When you have installed a drive that came from another system, like DVR, media player, NAS, hard disk recorder, Game console etc. it is possible that the drives won't be recognized by Windows. This is because it is formatted in a way that windows do not support. When you need to use these hard disks, you have to re-format the drives in the Windows NTFS file system. When this is not possible from the Windows disk manager, you could try 3rd party apps, like “Gparted” and “MiniTool Partition Wizard” etc.

Please note! When you use an existing hard disk from another system, and you repartition and format the drive. All the data will be lost on that partition. 

Please create a backup first, on the system where the hard disk was originally used for. After this you can remove the disk and place it in the housing. We are not liable for any data loss.
