Hard Drive Formatting Error in Terminal I have tried formatting and partitioning this brand new hard drive and it has failed on multiple computers using multiple methods. It is a LaCie Porsche Design 4TB hard drive.

Here is the commands I have been running:

$ diskutil list disk4
/dev/disk4

$ diskutil list

   2:                  Apple_HFS                         4.0 TB     disk4s2


Then here is where it appears I have ran into trouble:

$ sudo newfs_hfs -v "4TB" -J /dev/rdisk4s2
newfs_hfs: WriteBuffer:  pwrite(3, 0x10dfba000, 131072, 450764800): Resource busy
newfs_hfs: write (sector 110050): Invalid argument


Any ideas of what I might be doing wrong or what I can do to fix it?

Many thanks!
Try to verify the HDD from disk utility and repair permission if this is doesn't work, try to format it using windows machine.
