My favorite tool for that is the "dd" command that comes with macOS. It needs to be used from the Terminal, so if that puts you off - there are also GUI alternatives.
"dd" is quite simple and will copy all data - including "free" areas. You take a clone by first rebooting your computer into Recovery mode.
Then mount an external drive where you want to ...
Moving by cut & paste is not really that different from copying and deleting, no.
The explanation for the data loss is buffering. When you ask Finder to cut & paste (or copy and delete - doesn't matter) - all that Finder does it ask the operating system to copy data to the external drive and delete the file from the internal drive.
The operating ...
I saved my SSD partitions with TestDisk
My partition table did gone and My SSD has two partitions, first one is NTFS and second one is mac os extended.
And I save my partition table like this guide.
The common cause of a bus powered drive not operating is the computer isn’t getting enough power through the cable you are using to power the unit.

Even though it is an external drive, the encryption system being used is still FileVault.
There's currently no method to cancel a decryption of the drive. You'll have to wait until the drive is fully decrypted, and then re-encrypt it.
If you are able to repair you drive, then you will need to be running at least Sierra in order to mount the macOS partition on the SSD via USB.
Below are two possible solutions.
Using a Third Party Tool
Since you already have the SSD connected as disk2 in a USB port, a simple solution would be to download and use gdisk.
The current gdisk installer is ...
This is the official answer from me on what fixed the issue.
If you run into this same situation(rare case really) this is how it was fixed.
The background: MBP 2016 with TB, updated normally, converted to APFS and had at one point windows running on it with bootcamp.
I decided to format the drive and reinstall clean because i had a lot of clutter on it and ...
Helo, and welcome to Ask Different. (Please excuse my spelling, for some reason Ask Different deletes the word if I start with the word hello.)
Your problem might be that you're restarting into your Recovery Partition instead of your external Installer.
You can boot into your installer by pressing Option when restarting, and then selecting to restart into ...
I'm assuming you've disabled SecureBoot, and that the volume name is identical in what follows:
It's possible that the T2 chip on these new (2018) Minis makes 'straight' cloning difficult.
I had the same problem when I cloned my old 2012 Mini's volume onto my 2018 Mini : I too got a flashing question mark. I was able to fix it by installing Mojave on top ...
my system will freeze if I don't pull it out.
Something is amiss with your system. This isn't normal behavior. Let's look for the root cause of why this is happening.
What happens if you reboot?
You should try a reset of your i/o system.
Try a safe boot. Should you drive work fine in safe mode, it means some ...
From Ubuntu, you need to run the command gdisk.
Open a Terminal. Basically, press the control+alt/option key combination.

sudo gdisk /dev/sda
If the version is not at least 1.0.4, then enter the q command to exit gdisk. Next, enter the commands given below to update gdisk, then return to step 2. Otherwise, ...
If the second partition on HDD is for Mac data, you could attempt to install Windows 10 by allocating the entire HDD to Windows. After you have finished installing Windows, you could then shrink the Windows volume and create a partition for the Mac data.
If you are getting the answer to this question, dear friends, here's the answer: I hope it will help you.
Fix MacOs: This Item Is Temporarily Unavailable. Please Try Again Later error
Moving the entire user domain, instead of just the folders for Videos and Photos may be overkill, though it would keep things simple. You're not going to see any advantage from moving preferences, audio files, Word docs, etc, as they are too small and not causing any bottleneck.
There's no disadvantage either, except that if the Mac boots up and can't find ...
I got a 2018 Mac Mini as a gift but only a 256GB drive. My user profile is almost that size. So I got a 1TB SSD and a nice USB-C/Thunderbolt case and copied the profile over there. Works a treat for me.
Once you have copied her profile to the external drive go into System Preferences > Users and Groups and Control Click on her user name and select ...
To answer my own question:
Most likely the issue was caused by the WD Driver Utility app, as reported by many in the WD forums.
If not that, it was caused by an unpowered 7x USB-A to USB-C hub that the HDD was connected to earlier.
Either way the problem is now gone.
Jettison is an excellent recommendation, and probably the one I would make for most people.
However, if you want to get into all sorts of Mac automation, you'll definitely want to checkout Keyboard Maestro. You can create a macro that will run when the system goes to sleep, and have that macro run a simple shell script like this:
I had the same issue before with my 4TB Seagate external hard drive too. It also takes too long for the system to recognize my disk, and a lot more issues came with it.
If you unplugged your drive without unmounting / ejecting it properly, it could potentially been occupied by some processes such as quicklookd in the background, this can potentially cause ...
There may be a native way to accomplish your goal; however I do not know how and why I use EventScripts, which among the events it can react to, Computer will sleep and Computer wakes could be use to unmount/remount an attached USB Drive using AppleScripts, shell scripts and or Automator workflows.
You can download the demo version from the developers web ...
There's a 3rd party app available for exactly this purpose. Jettison app automatically ejects your external drives when you put your MacBook to sleep.
It is a paid app with 15 days of free trial available.
Reading the man page of diskutil, I found a command that I thought might provide at least some diagnostics on what was wrong:
When you run this command, it will start monitoring all disk activity and report back to you until you stop it again.
I ran this command and switched off the bricked external drive. Nothing happened.
I switched ...
It is not possible to stop the decryption of the drive while also using the drive.
You can unmount and possibly unplug the external drive, and the decryption will obviously stop.
However, as soon as you plug the drive in again and mount the file system, the decryption process will continue. You cannot ask the system to stop that.
Your options are either ...
Did you try clearing Purgeable Space on your Mac? If not, you can follow these steps to remove Purgeable space on your Mac running Sierra or Mojave:
Open the Terminal application in Applications/Utilities.
Enter the following into the Terminal window to start making a file that will
grow until the disk is full: dd if=/dev/zero of=~/stupidfile.crap
On the assumption that you have APFS file system, macOS 10.14 Mojave, and local snapshots - the system might take some time to purge the space.
The way to know this would be to open the system information and give it several minutes to catalog all the space into buckets.
Second - check for local snapshots
tmutil listlocalsnapshots /
There are command ...
