Reformatting hard drive

[Dawg77]

I have a Rasp Pi 2 with OSMC installed on the micro sd card. I want to add a hard drive just to store video and music. The hard drive is presently formatted in ext4 as one large partition. I would like to format it in ntfs. What process/commands do I need to run to accomplish this? I would like to leave it as one large partition. Thanks.

If you really want to do this (and lots of people here will, any minute now, be either sarcastically asking you why you want to do it and/or telling you you don't want to do it), then the easiest way to do it is on your Windows machine.

I'm pretty sure it can be done on Linux, using the appropriate mkfs.whatever, but it isn't worth the risk, since formatting is a one-time action - just do it on the Windows side and be done with it.

Is the drive only going to be used on your RPi or are you going to unplug it and mount it on a Windows system?
Have you considered leaving it as ext4 and using Samba to make it available across the network to your Windows system?

NTFS on Linux has a couple of serious disadvantages: 1. security stops at the mount command 2. the ntfs-3g driver runs in userspace not in the kernel so you lose lots of CPU running it. Is it worth that for the small benefit of being able to plug it in to a Windows system and use it directly?
