AC1510 My Hard Disk is not recognized in Windows explorer

  • Updated

When you have placed a new Hard Drive into your external casing, it is normal that Windows Explorer does not yet recognize the Hard Drive

Windows works with logical volumes, which 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 etcetera. it is possible that Windows will not recognize the drives. This is because it is formatted in a way, which Microsoft Windows does 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 data will be lost on that partition. 

Please create a backup first, on the system where the Hard Disk originally is coming from. After this you can remove the Disk and place it in the housing. We are not liable for any data loss.
