It is a USB enclosure HDD. I tried DISKPART->CLEAN but CLEAN said it can't find the partition. Thank you for any help.
You have to wipe out ALL current partitions on the HDD, create a new one, & then format. If you want to do it from Windows rather than a boot disk, download & install Easeus Partition Master Free edition.
Have you looked to see if the drive is seen in Disk Managment?
You don't format it to NTFS, you partition it to NTFS. Formatting comes after you create the NTFS partition.

Technically speaking if the file system on the external HDD is FAT32, you do not need to do anything. Windows will recognize it if the HDD is working properly. Otherwise follow the posts above to get rid of Apple HFS+ file system. i_Xp/Vista/W7/W10 User
Plug it in to the PC and open Disk Manager. If the drive shows up there, right click on any existing partitions shown and select Delete Partition. Then when it shows Raw or unpartitioned drive, right click on it again and select to Partition it. Leave it the full size of the drive as shown or decide on the size of the partition you are making and create it. Then right click on the new partition and Format it to NTFS and you are done. IF you want to be able to use it on PC's and Mac's then make it FAT32 instead of NTFS. You have to be a little bit crazy to keep you from going insane.
Thank you. Unfortunately the drive is not visible in Disk Manager. I ended up having to use DISKPART and then Disk Manager.
Yes, it is not. I had to learn how to use DISKPART correctly before Disk Manager could see and initialize and format it.
Thank you. I ended up figuring out how to use DISKPART and then Disk Manager before I saw your post. I am going to download that program for next time.
So as noted, ultimately I had to figure out how to use DISKPART to delete all three HFS+ partitions, and then Disk Manager could see it and create and format the drive as an NTFS partition. Thanks to all.
