I am doing a dd
on two identical drives with this command:
dd if=/dev/sda of=/dev/sdb bs=4096
Both hard drives are the exact same model number, and both have 1TB of storage space. /dev/sda
uses a blocksize of 4096. /dev/sda
is a local drive and /dev/sdb
is a remote caddy. I might be able to use the following protocols:
- USB2.0 HighSpeed (Currently the plan)
- Gigabit Over-The-Network clone (Really do not want to even try this)
- USB3.0 (If I find my other drive caddy)
- eSATA (If I find/buy a cable)
- SATA (If I find/buy a cable, gotta love laptop CD drives)
Is there a way to run this drive copy that takes less that 96 hours? I am open to using tools other than dd
.
I need to clone the following partitions (including UUIDs)
- Fat32 EFI Partition (*)
- NTFS Windows Partition (*)
- HFS+ OSX Partition
- EXT4 Ubuntu Partition (*)
- Swap Partition (*)

Supported by Clonezilla
I have tried Clonezilla (and it was MUCH faster), but it does not support HFS+ smart copying, which I need. Maybe the newest version supports this?
When I made my first clone, I did all of the partitions except HFS+ and it went very quickly. (No more than 3 hours total)
dd
copies everything, including free space. The disadvantages become extremely apparent when you have large disks that aren't completely full.
