I know it has been partly covered in posts before. But I never felt I had
enough info to copy disk to disk.
I have a spare disk here I thought I would give it a go with. The disk is a
:
Hitachi 100Gb 2.5
My disks are as follows:
a...@al-ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xaf010487
Device Boot Start End Blocks Id System
/dev/sda1 * 1 30401 244196001 83 Linux
Disk /dev/sdb: 100.0 GB, 100030242816 bytes
255 heads, 63 sectors/track, 12161 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xeed6ce43
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 12136 97482388+ 7 HPFS/NTFS
a...@al-ubuntu:~$
The 250Gb is my main linux drive and the 100Gb is the Hitachi. I have not
yet added another 2.5" drive to image to.
In fact for safetys sake I will image the 100Gb drive in its entirety to my
main linux drive (sda). This does raise my first question though:
1) When going disk to disk can you image both the whole drive and all its
partitions or can you only go disk to disk on a partition by partition
basis?
Off to copy the disk now:
a...@al-ubuntu:~$ sudo ddrescue -vn /dev/sdb /home/al/rhonda.bin rhonda.log
About to copy 100030 MBytes from /dev/sdb to /home/al/rhonda.bin
Starting positions: infile = 0 B, outfile = 0 B

Hard block size: 512 bytes

Copying non-tried blocks...
Look forward to any replies on what I need to do to write rhonda.bin off to
a new unformatted disk.
TIA
