This will give you a freshly formatted drive suitable for Time Machine backups. I have at least a dozen backup USB drives with capacity up to 2 TB, I rotate them to backup 5 different Macs. I have never used the mfgr software - just plug it in and wipe it with disk utility.
Often they come formatted NTFS ('mac' versions cost more for same drive but Mac format). I haven't had any problems with them - I use superduper to just do bootable image backups as I don't need the Time Machine style updates. The latest disk utility made it harder to set it up, but not a big deal. Once setup and split into several logical volumes, they have worked perfectly. Don't install any software from WD.
