How to ubuntu clone a partition from one disk to another.
This is simple enough but you could also use the GParted program disk that linux comes disk with Ubuntu to do the same.
linux If you use Windows XP/Vista, it might object to a new hard disk as part of its Windows Genuine Advantage system, and disk you might have to revalidate online.If you want to resize your Windows partition too, these steps are still relevant.There is a presumption that you know how to install a hard drive.You can run a quick check on the file systems of the new drive: e2fsck -fp /dev/sdb1 If the new drive is bigger than the old one you need to extend cloning the partition(s) on it or create another one to make use of the rest.Open a terminal window and type the command sudo fsck.Disk /dev/mapper/centos-swap: 859 MB, bytes, 1679360 sectors.Calling ioctl to re-read partition table.You might have to get the bios to recognize the new disk; in most cases that is not necessary.It ubuntu works both for a perfectly good drives that you would like to clone and for failed drives that you would want to recover data from. This needs to be installed because it isn't esxi a vmware default system tool.
The logical name of disk:0 is /dev/sda and the one for the second disk is /dev/sdb.
There have to be just a few basic things in place: The target drive should be the same size or bigger than the source disk drive.
Two hard disks are listed windows in the results: look for the headings Disk /dev/sda and Disk /dev/sdb.Dd is very disk effective and powerful command but it is not very suitable when you are trying to make a copy of a failing or failed disk.In the dialog box that appears, click and drag the graphical representation of the partition to the end of the free space (in other words, click and drag it to the right of the graphical display).Making upside an exact copy of a hard drive (or any drive for that matter CD, DVD, USB, etc.) is very easy and quick with Linux.It is a very powerful utility that was originally developed for the unix operating system and is now default on every Linux distribution.Although the computer is running the Ubuntu install CD objective-c live distro mode, it's still possible to install additional software from the online repositories.Third, once ddrescue has finished, you must use the Gparted utility to expand the disk partition(s) (assuming that the new disk is bigger than the old one, which is almost certainly going to be the reason for upgrading in the first place).The GParted program that comes with Ubuntu is ideal for this.So typically your hard disk drive is a file in the /dev directory with the prefix of hd or sd (depending on IDE or scsi driver).The above command splits the backup image file to smaller files of size 50MB or less.First, back up all valuable personal files to CD/DVD-R/RW disc, a USB keystick, ipad or an external hard disk.What is on the hard disk is irrelevant; it could be Windows, Mac OS, Linux, just data, etc.Community-maintained Open Source software (universe).
