I wasn't sure where to put this thread but since i use ubuntu for data recovery, I figured this is the best place. So, a friend passed me a 250G Western Digital hard disk the other day and said that his client needs to get her pictures off it. the problem: windows says it wants to reformat the system. so i put in my linux disk and had a look.
when i ran dmesg as root shortly after connecting the drive it gave the output in dmesg.txt i attached
I looked at the original drive with fdisk -l. I have made an image that I will be working with.
I had the same output when i used sfdisk on the image.
mount -o loop to /mnt fails it wants me to specify a filesystem and when i do it spits out a dmesg tail error.
is there anything else i can try like specifying an offset?
could anyone give me a general idea of how i may clone a 2 Gig disk running Solaris 7 on it to another disk of the same size?
currently, this system only has one disk in it though. i do have the ability to hook up another disk via SCSI.
i have been told i need to boot to "miniroot" to run... (9 Replies)

Disk cloning
I had an external SCSI master disk that I used to clone to an identical external SCSI disk because the other SCSI disk would become corrupted. My original Master became corrupted so I used one of the other to good disk to copy back to the master. Unfortunately the new master needs... (1 Reply)
Hi.
We tried cloning a SCO Unix hard disk using Norton Ghost.
However, the new cloned hard disk encounter booting problem.

Continuing saga of working on making a retail store more robust by creating a backup clone of the main server, a 1995 era :eek: PC running SCO OpenServer 5.0.0b and a discontinued Point of Sales (POS) software system.

hello folks,
I have a 300GB ROOTVG volume groups with one filesystem /backup having 200GB allocated space
Now, I cannot alt disk clone or mirrorvg this hdisk with another smaller disk. The disk size has to be 300GB; I tried alt disk clone and mirrorvg , it doesn't work. you cannot copy LVs as... (9 Replies)
Guys can anyone tell how can we do faster disk cloning
Below i found in google
1. dd if=/dev/sda of=/dev/sdb bs=4096 conv=noerror,sync
So adding "conv=noerror,sync " makes it faster looks against not adding it
2. Enable write cache activated (hdparm -W1 /dev/sda) then run dd ..

Hi,
I am trying to clone the hard disk image of Solaris OS on one disk to another disk. After some googling I found that there is a command "dd" to achieve this.
However there is a condition to use the dd command, that the disk geometry of both the disks (source and target disks) should... (5 Replies)

dmesg
DMESG(1) User Commands DMESG(1)NAME
dmesg - print or control the kernel ring buffer
SYNOPSIS
dmesg [options]
dmesg --clear
dmesg --read-clear [options]
dmesg --console-level level
dmesg --console-on
dmesg --console-off
DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.
The default action is to read all messages from kernel ring buffer.
OPTIONS
The --clear, --read-clear, --console-on, --console-off and --console-level options are mutually exclusive.
-C, --clear
Clear the ring buffer.
-c, --read-clear
Clear the ring buffer contents after printing.
-D, --console-off
Disable printing messages to the console.
-d, --show-delta
Display the timestamp and time delta spent between messages. If used together with --notime then only the time delta without the
timestamp is printed.
-E, --console-on
Enable printing messages to the console.
-f, --facility list
Restrict output to defined (comma separated) list of facilities. For example
dmesg --facility=daemon
will print messages from system daemons only. For all supported facilities see dmesg --help output.
-h, --help
Print a help text and exit.
-k, --kernel
Print kernel messages.
-l, --level list
Restrict output to defined (comma separated) list of levels. For example
dmesg --level=err,warn
will print error and warning messages only. For all supported levels see dmesg --help output.
-n, --console-level level
Set the level at which logging of messages is done to the console. The level is a level number or abbreviation of the level name.
For all supported levels see dmesg --help output.
For example, -n 1 or -n alert prevents all messages, except emergency (panic) messages, from appearing on the console. All levels
of messages are still written to /proc/kmsg, so syslogd(8) can still be used to control exactly where kernel messages appear. When
the -n option is used, dmesg will not print or clear the kernel ring buffer.
-r, --raw
Print the raw message buffer, i.e., don't strip the log level prefixes.
-s, --buffer-size size
Use a buffer of size to query the kernel ring buffer. This is 16392 by default. (The default kernel syslog buffer size was 4096 at
first, 8192 since 1.3.54, 16384 since 2.1.113.) If you have set the kernel buffer to be larger than the default then this option
can be used to view the entire buffer.
-T, --ctime
Print human readable timestamps. The timestamp could be inaccurate!
The time source used for the logs is not updated after system SUSPEND/RESUME.
-t, --notime
Don't print kernel's timestampts.
-u, --userspace
Print userspace messages.
-V, --version
Output version information and exit.
-x, --decode
Decode facility and level (priority) number to human readable prefixes.
