DDRescue me... please..

[mufngruf ()]

Please forgive me if this is a resend... I'm new to this system - duh!

I have an intel imac which does basic stuff, cos that's mostly what I need. I have an old ibook which has lots of family stuff on it and the small drive seems to have become suddenly corrupted.. "the volume could not be repaired - underlying task reported failure on exit" and that sort of thing. Disk warrior, or disk utility cannot rebuild/repair the thing. I can get it to start up with the installation disk in the drive but it will not install a new system on the existing volume unless I reformat the drive - and lose all the data.
I can firewire target the disc and it shows up on the imac but I cannot drag any files across... it just seizes up both machines when I try. I don't think there's a "mount point" - whatever that is..
I do not understand even the most basic command line instructions... which is why, after all the other newbies got their questions answered, I STILL can't figure it out.
I have downloaded ddrescue-1.10 which contains 20 items - none of which can I recognise as anything that I can do anything with.
Please pretend that you have to give a step by step in this process to a small, albeit fairly smart, kid who just glazes over at the technotalk.
Can anyone please help. I'm not trying to save the drive, just the data.
Thank you in advance for your time, patience AND CONSIDERATION.

There are several ways you could proceed.  Basically you need to create a copy of the bad disk bit by bit onto a good disk, preferably a new one.  To achive this you need the bad disk and the good disk connected to the same machine, which can be as simple as plugging them into spare slots on a desktop machine or by using a sata usb cable like the one here http://www.pccasegear.com/index.php?main_page=product_info&products_id=8423.  I would strongly suggest removing any other disks from that machine so there is no way possible to overwrite anything you want.   When you have them connected you boot this machine off a program like systemrescuecd   http://www.sysresccd.org/Main_Page  that runs from a cd drive or usb flash disk.  From there you would use ddrescue from the command line to copy as much of the bad disk as possible to the good disk so you can do data recovery on the good disk.  It is important not to work the bad disk any more than necessary it as it might fail completely at any time.  The new disk must be as big or larger than the bad one and you use a command like     fdisk -l    to find the path, which will be something like     /dev/sda    and    /dev/sdb   .  


I dont know if system rescue cd will work with a fire wire connection. 

You dont need to mount either bad or good disks for ddrescue to work so dont worry about it, but do take my advice and physically remove any other disks from the machine before you begin.

[Charles Hemingway-2]

mufngruf:

Since you mentioned that this is an old ibook, I'll assume it's PPC Mac
with a Macintosh bootlabel.  You'll have to look closely when you snag
your partition, the first 6 or 8 are typically Macintosh HD drivers for
OS 9.  Even if you only used OS X on this notebook, chances are the OS 9
HD drivers are in there.

For instance, my primary OS X disk is /dev/sda9 in my PowerBook.  Your
experience may be different, and it may move around when you put it into
another machine.  Also, do a google search for iBook Take Apart, and try
to be specific (iBook, iBook SE, Late 2001 etc). The differences are
important.  Go here if you need clarification: http://apple-history.com/

Good Luck,
Charles

Whoa there guys...

By his own admission he is 'Smart but confused by all the technotalk...."

Perhaps a better suggestion would be to find a friend / local tech who understands Linux etc & can help him out or at least make sure he doesn't dig himself into an even bigger hole....

Apoligies if this posts twice - I got confused by nabble & registered with a different Email address to the list subscription...
