4/26/2023 0 Comments Clone mac hard drive to ssd$ sudo dd if=/dev/sda of=/dev/sdb bs=64K conv=noerror,sync Note: Mac systems usually refer to disks as "disk0", "disk1" etc. While this simple command and and does work in most cases It is considered unstable as the dd utility will skip every error it encounters which can cause an error. The MacOS disk utility (diskutil) can help achieve this task. However, this command will not work on Mac systems. Normally the command used to display all disks looks like this: "sudo fdisk -l". Normally, in a Linux system, "sda" represents the first disk and "sdb" would represents the secondary disk. "of" is of course, the output file - our target drive. "if" is the input file - it is the original drive we wish to clone. "sudo" is necessary as we are cloning a system drive. You will have to be familiar with the command line interface (Terminal). This cloning method works on Macs, Linux, FreeBSD and any unix-based systems. It evolves a command line utility called "dd" ( Wikipedia) mainly used to copy and convert files. In the process of upgrading my Mac SSD drive (which is a whole story of its own), I've come across many different methods of doing so.Īt one time, I was keeping "Time Machine" backups regularly which made the whole process quick and easy I swapped the SSD cards and restored the most recent Time Machine backup from the hard drive I was keeping the backups on.Įventually, I came across another method that I was already familiar with already but didn't think of in this particular scenario.
