I'm running (via Boot Camp) Windows 7 SP1 on my 32-bit MacBook, and I'm trying to format a new Western Digital My Passport external hard drive to use NTFS. It came formatted of course but I wiped it clean. Disk Management says the drive is RAW, healthy, and primary partition on that hard drive. I just want one NTFS partition, but I can't get Disk Management to do it -- I just keep getting messages saying that the disk is in use. I tried booting into safe mode and formatting the disk there, but that didn't help. Does anyone have any idea how I can get this to work??
Well, I don't know exactly what was wrong, but I fixed the problem:
- Booted into OS X
- Used Disk Utility to format the hard drive using ExFAT (it worked on the first try; took about 3 seconds)
- Booted into Windows
- Used Disk Management to reformat the hard drive using NTFS (it worked on the first try; also took about 3 seconds)
That's it. Presto.
