What do you mean free space?  Did you partition it and create sdc1 to be 345 gigs in size?

Because the following command write directly to sdc1:

sudo ddrescue --no-split /dev/sda2 /dev/sdc1

Whatever filesystem was on scd1 is gone.  It is overwritten with what is on sda2.  It's possible to write to a file which will only take up the free space on a device.  You do so by mounting the device and telling ddrescue that the image is (to be) the filename.


cd /media/MyExternalDiskWith345GigsOfFreeSpace
mkdir rescued
cd rescued
sudo ddrescue /dev/sda2 image log

That will create an image of sda2 on your external drive.  The image will named "image" and the log will be called "log".

I hope that I am wrong and that you didn't just blow away most of the data you had saved on the external drive.

I'm trying to recover data from a HD that wont boot.  It's my daughters
computer, only 2 years old and it contains the raw baby pictures of my only
grandchild.  I know, I know...

After researching (frantically) I came across some information on ubuntu
live cd and gddrescue.  I ran the following command:

sudo ddrescue --no-split /dev/sda2 /dev/sdc1

Note: prior to launching this command I tried the same command but with a
logfile name.  It didn't work because the logfile didn't actually exist. 

I skipped the logfile cuz I wasn't sure my external drive had enough room
for the image file as well as the logfile...

My HD is 320 GB.  My external drive has approximately 345 GB of free space.

ddrescue has been running for two days and has the following info...

rescued: 177660 MB
ipos: 177877 MB
opos: 177877 MB

I'm starting to worry about whether or not I launched with the correct
settings, whether my external drive should have been empty, should I have
started the rescue with /dev/sda1 (I think this was a vista recovery
partition), etc...

Should restart now while I'm only 2 days into it, if I did infact blow it?

Any suggestions at this point would be greatly appreciated.
