I am using 'dd' to clone an entire hard drive which only has Ubuntu 11.10 and some data with no special options. The disks are both 1Tb, However, I did re-partition the target disk with gparted successfully. The new partions are not the same size as the source disk. When starting 'dd' no partitions were specified in the target. e.g.
Normally this would take no more than an hour using WD Acronis software, but this does not produce a bootable disk.
'dd' has now been running for seven hours without any apparent progress. When should I stop it please?

Hello everybody,
:confused:
I have to change the system disk on an old PC running SCO 5.0.5.
The disk is up and running, this is a preventive action.
My experience on UNIX is very limited and I look for the easyest solution to clone this unit.
Is it possible with commands or through a clone... (2 Replies)
I am using ufsdump and ufsrestore to clone the root disk on one of my servers. I would like to automate this as much as possible, but have run into a problem where it prompts for changing the owner/mode when it is complete.
Any ideas for running this in the background and not being prompted?

Hello guys!
I use the Solaris 10 x86 machine.
I need to clone the boot disk.
Why, when I copy slice 1 - there is a following:
# ufsdump 0f - /dev/rdsk/c0d0s1 | (cd /mnt && ufsrestore rf - )
DUMP: Warning - super-block on device `/dev/rdsk/c0d01` is corrupt - run fsck

Hi,
I'm running Ubuntu on my laptop. To keep my data safe and easy disaster recovery as well I bought similar HDD to one installed in my laptop with higher capacity and using USB box I'm doing disk clone to it. So at any time I can replace disk and carry on with my work as before.

Dear All
I needed to clone my disk to another hard drive . I did it as the following :

SD(4) Linux Programmer's Manual SD(4)NAME
sd - driver for SCSI disk drives
SYNOPSIS
#include <linux/hdreg.h> /* for HDIO_GETGEO */
#include <linux/fs.h> /* for BLKGETSIZE and BLKRRPART */
CONFIGURATION
The block device name has the following form: sdlp, where l is a letter denoting the physical drive, and p is a number denoting the parti-
tion on that physical drive. Often, the partition number, p, will be left off when the device corresponds to the whole drive.
SCSI disks have a major device number of 8, and a minor device number of the form (16 * drive_number) + partition_number, where drive_num-
ber is the number of the physical drive in order of detection, and partition_number is as follows:
+3 partition 0 is the whole drive
partitions 1-4 are the DOS "primary" partitions
partitions 5-8 are the DOS "extended" (or "logical") partitions
For example, /dev/sda will have major 8, minor 0, and will refer to all of the first SCSI drive in the system; and /dev/sdb3 will have
major 8, minor 19, and will refer to the third DOS "primary" partition on the second SCSI drive in the system.
At this time, only block devices are provided. Raw devices have not yet been implemented.
DESCRIPTION
The following ioctls are provided:
HDIO_GETGEO
Returns the BIOS disk parameters in the following structure:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
A pointer to this structure is passed as the ioctl(2) parameter.
The information returned in the parameter is the disk geometry of the drive as understood by DOS! This geometry is not the physical
geometry of the drive. It is used when constructing the drive's partition table, however, and is needed for convenient operation of
fdisk(1), efdisk(1), and lilo(1). If the geometry information is not available, zero will be returned for all of the parameters.
BLKGETSIZE
Returns the device size in sectors. The ioctl(2) parameter should be a pointer to a long.
BLKRRPART
Forces a reread of the SCSI disk partition tables. No parameter is needed.
The SCSI ioctl(2) operations are also supported. If the ioctl(2) parameter is required, and it is NULL, then ioctl(2) fails with
the error EINVAL.
