The title is self-explained: I want to change the hard disk name (not the partition). I am not able to do it with Disk Utility. Any solutions?

I'm on Yosemite

  • I'd like to see a picture attached to the question, similar to klanomath's, but showing the entire Disk Utility window so we can see format type etc. I've never seen a drive that cannot identify itself... but many partitions called UNTITLED (especially if they're FAT/NTFS) – Tetsujin Oct 29 '14 at 9:36

The device name is probably hard coded into the PCB or soft coded into the Service Area of the platter (aka hard drive firmware) and might be changed by the manufacturer but not by the customer.

The partition name (green) might be changed easily, the device name (red) not.

  • Thanks for the answer. I was asking that because the hard disk I installed (Samsung SSD 850 PRO) has not that name but it's called "Untitled"! It's horrible. Then I can't change it? Is it normal that the SSD is called Untitled? – Fred K Oct 28 '14 at 8:59
  • @fred k I'm searching for a better answer. Maybe it's working like that: the firmware provides some (fixed) hex values for size, manufacturer, product number etc. and one editable file in the depth of the system contains human readable transliterations where your disk might be added. – klanomath Oct 28 '14 at 19:07

Try diskutil cs rename lvgUUID "newName". You will need a lvgUUID(Logical Volume Group): diskutil cs list.

    Could you elaborate on why or how the physical name of the disk would be enmeshed with the core storage volumes (if any) on that drive? – bmike Feb 10 '15 at 14:34

If you go to Finder > Preferences > General, mark Show hard disks it appears on the desktop, then select it with single left click and press Enter.

    that is the hard disk, you can't give a partition a name as the user never sees it. – Steve Chambers Oct 28 '14 at 14:30

    ermm... no - that's the partition. That's all the user usually sees. – Tetsujin Oct 28 '14 at 18:55

Easy Fix Go to System Preferences - User and Groups, Righthand click on Admin User this will open advanced options, account name and Full name can be changed from there!!


want to know how? Connect it to a windows computer. Press rename. Done

  • Same result as changing the Volume name on a Mac, it doesn't change the device name, which is hard-coded – Tetsujin Sep 10 '15 at 17:11
