How to clone a hard disk or USB stick in the terminal.
- No need to purchase any special software, here is how to do it!
- Widely used before Mac OS X, can be considered as a more elaborate extended attribute system, and may also hold main data of the file. (See: Mac OS X Resource Fork and Command Line Tips) View Extended Attribute with ls. Ls -l -@ filename. Ls -l -@ filename show extended attribute Show Attribute with xattr.
- Mac OS X ship dates. Like any major software undertaking, Mac OS X was perpetually late. Apple promised Mac OS X would finally ship in the fall of 2000. Like anything associated with this story, there is no YouTube video, no transcript, nothing. You only have my word on it.
By pressing certain key combinations, you can do things that normally need a mouse, trackpad, or other input device. To use a keyboard shortcut, press and hold one or more modifier keys and then press the last key of the shortcut. For example, to use Command-C (copy), press and hold the Command key, then the C key, then release both keys.

Use the Remove Sophos Endpoint tool Click the keys command + spacebar to open Spotlight. Type Remove Sophos. Note: If the tool exists or hasn't been moved to Trash, Spotlight will.
dd (disk duplication) is a Mac OS X command-line utility which can read raw data off a disk, even if the Mac doesn't understand the filesystem. There's also a freeware version of dd for Windows available, with instructions.
dd arguments:if=
specifies input path (file, or device)of=
specifies output path (file, or device)bs=n
sets both input and output block size (optional, default=512 byte blocks)conv=noerror,sync
tells dd to be fault-tolerant and ignore read errors (optional)
If the operation stops with an I/O error, try to salvage all readable data with conv=noerror,sync
.
This option can often recover a dead hard drive, or an unreadable file, but it does not repair the error.
Make a working copy of a Signalling Server hard disk
If the installation has primary and backup signalling servers, clone one at a time to avoid service interruption.
Flowingsilver mac os. Open Terminal and try this:
1. Attach and identify the source disk ⇒ | diskutil list |
2. Unmount the source disk ⇒ | diskutil unmountDisk /dev/disk2 |
3. Copy the source disk to the desktop ⇒ | sudo dd if=/dev/disk2 of=/Users/mike/diskimage.img |
4. Attach and identify the destination disk ⇒ | diskutil list |
5. Unmount the destination disk ⇒ | diskutil unmountDisk /dev/disk2 |
6. Copy the image to the destination disk ⇒ | sudo dd of=/dev/disk2 if=/Users/mike/diskimage.img |
The second dd command is almost the same, but if and of are reversed. Discoships mac os. BECAREFUL!
If the copy fails due to disk errors, try using the following command at step 3:

dd if=/dev/disk2 of=/Users/mike/diskimage.img conv=noerror,sync
dd will take much longer using this option, errors are written as NUL bytes. Watch mac os. chkdsk it.

- Make sure the destination has enough space for the disk image, eg, equal to (or greater than) the source
- If you can attach both disks, copy directly (much quicker):
sudo dd if=/dev/disk2 of=/dev/disk3 bs=64k
- Be VERY careful with
if
(input file) andof
(output file). Don't mix them up! - Using
/dev/rdisk#
(raw disk) in place of/dev/disk#
is much faster - Specifying a larger block size (bs=1m) doesn't seem to make much difference, though YMMV!
- You can check progress, while the command is running, by pressing Ctrl-T
You can use this procedure with any drive: eq, to clone an MGC Compact Flash from one with a known password.
Example:
Attach the SOURCE disk.
If the following warning appears, click Ignore:
Open Terminal, identify the disk and unmount it:
Now we can make an image with dd.
This will take a long time, and there is no progress bar. You also need enough local disk space for the image.
Another option, if you can concurrently attach both disks, it to copy directly: sudo dd if=/dev/disk2 of=/dev/disk3 bs=64k
Switch disks, and copy the image to it. Here, it also mounts as /dev/disk2
The dd command is almost the same, but if and of are reversed. BECAREFUL!
