How do you copy a HDD partition as a folder to another HDD?

[noidly1]

Sorry if in the wrong area.

I have a PC that I want to copy its internal HHD partition c: as a folder to another external HDD.

The PC in question has a problem and won't boot. I have a thumb drive with Dabien 12 on it that I want to use to copy the entire c: drive to an external HDD. I have tried using Dolphin but it doesn't give me that option. Unlike windows, I can not right click a folder or use control/click folder to check multiple folders to copy. and then paste to the external HDD.This is frustrating...
All I'm trying to do is copy the entire partition to another drive so I can re-install my os on the internal and be able to copy the saved files back onto it.

Please help..
Thanks.

Are you sure the drive isn't bad and caused the no boot situation?

You could take the drive out and hook it up as a slave drive in another pc or external closure and then copy away.

You can use a tool like dd in the terminal to clone the entire partition to an external HDD; just run dd if=/dev/sdX1 of=/dev/sdY1 bs=4M (replace sdX1 with your source partition and sdY1 with your destination partition.

If you must copy everything including the system files you might want to consider using rsync instead. Example:

bash
Копировать код
The following command must be executed with sudo level access: sudo rsync -av /path/to/internal/partition/ /path/to/external/drive/
This is important to maintain copies of all files including the hidden ones in the personal computer. When this is through, all your files will be backed on the external drive and the operating system can be reinstalled. Give me a hint if you need any more help on that!

You can use the dd command in Linux to copy the partition to an external drive. For example:

javascript

sudo dd if=/dev/sda1 of=/dev/sdb1 bs=4M status=progress
Just replace /dev/sda1 with the source partition and /dev/sdb1 with the destination drive. Make sure to double-check the drives to avoid overwriting anything important.

To copy your HDD partition (C to an external HDD using Debian 12
You can use the dd command or rsync via the terminal. You can use these ways

1: Using dd (Exact Partition Clone)
Boot into Debian 12 from your thumb drive.

Open a terminal and identify your drives using the lsblk command. Find your internal HDD partition (likely /dev/sdX1) and the external HDD (e.g., /dev/sdY).

Run the following command to clone the partition to the external HDD:

bash
Copy code
sudo dd if=/dev/sdX1 of=/path/to/external/hdd/image_file.img bs=64K conv=sync
Replace /dev/sdX1 with your internal HDD partition and /path/to/external/hdd with the external HDD path.
This will create an image file of your partition on the external HDD.
To restore later, use:

javascript
Copy code
sudo dd if=/path/to/external/hdd/image_file.img of=/dev/sdX1
Option 2: Using rsync (Copy Files Only)
Mount both your internal partition and external HDD.
Use rsync to copy the files:
bash
Copy code
sudo rsync -avh /path/to/mounted/internal_partition/ /path/to/mounted/external_hdd/
This will preserve file permissions and copy everything.
