How to Copy a Hard Drive DD
- 1). Login to the Linux computer using the super user or root-account credentials.
- 2). Type "fdisk -l | grep Disk" and press the "Enter" key. In the drive output note the hard-drive device with the larger space is the destination hard drive.
- 3). Type "df--h" and press the "Enter" key. Note that hard drive partitions are listed in the "Filesystem" column in the form of "/dev/xxx1." The "/dev/xxx" portion represents the drive device, and the number at the end represents the partition. Confirm that the space available (in the "Avail" column) on one of the destination hard-drive partitions is greater than the total space used on the source hard drive (in the "Used" column) before proceeding.
- 4). Type "dd if=/dev/sdc of=/dev/sdd1/hdimage.img." Substitute the "/dev/sdc" with the actual device name of the source hard-drive device. Substitute "/dev/sdd1" with the actual device name of the destination hard-drive device partition that has more space than the source drive.
- 5). Press the "Enter" key and the "dd" utility will copy the source hard-drive contents to the designated destination hard-drive partition.
