I put this question:
I'm trying to recover my data files from a External
3.0USB 1TB Hard Disk (
HFS+ File System) can be identified with the Black color, then I have another with the same characteristic to copy my recovered files with the Gray color. On Ubuntu I can't write using
HFS+ then I formatted the HDD Destiny/Gray like
Ext4 File System.
I can see the tree and the files in Ubuntu, but in macOS not (using Finder)!!!
I can't see my files on macOS Sierra my Hard Disk have HFS+ File System (originally used by macOS).
Now I'm using
ddrescue on Linux Ubuntu 17.04. but it is possible to use this command on macOS Sierra too!
But my machine (MacBook Air) only has two
Like I haven't Ubuntu installed, I need a Live Version, using a Stick (I have a
3.0USB 16GB Stick).
But the disks
Destiny/Gray are External, then I need a USB Hub.
Then to use a Ubuntu Live through a external
3.0USB Stick I need to use a USB hub, only I have a
2.0USB Hub with Silver color, and the speed allowed on
2.0USB is sensible lower than
ddrescue can take months using
2.0USB Hub to connect the Two HDD's in recover process.
Can I to do this process on macOS Sierra side (with its SSD HDD - only I have 15GB free space), using the two
3.0USB ports to connect the Source/Black and Destiny/Gray (using
HFS+ File System) HDD's to improve the speed?.
Can be the results different?
dd command is recommended to unmount the hard disk's, is needed in ddrescue and dd_rescue too?
I-m trying to recover my data on macOS side in this questions:
