Re: [PLUG] ddrescue/dd_rescue question

download partedmagic.
It can mount ntfs partitions and copy them to another drive,
and newer releases of partedmagic include clonezilla which is an open source
alternative to ghost.
If you have patience, this will be the topic of my November
PLUG Central Presentation.

Neither the man nor how-to pages on the web seem to answer this.
I want to try to rescue some
files from a 300 GB NTFS partition. I have an empty 160 GB drive to use as the
target. There are only 108 GB used on the NTFS partition. Do ddrescue and
dd_rescue copy free space, meaning I need a 300 GB target, or will the 160 GB
target be enough for the <108 GB of data?
I really only want to copy
the user files. ddrescue/dd_rescue seem only to work on whole partitions. Is
there a better solution that works as well on distinct source files? rsync,
even with --ignore-errors freezes bash on this drive.
AFAIK dd_rescue,
just like regular dd, copies every single bit on the hard disk, including the
ones that are not in use by files. You might be able to use dd_rescue to
copy to a smaller hard disk if it supports writing a compressed image (e.g.
gzip, bzip2) or stddout, but otherwise you'll have to have a bigger
target.
I don't know of any programs designed to rescue specific files
from a bad disk. There are plenty of programs that will rescue files from
corrupt filesystems (and perhaps you'll need one of those as well) but it's
probably best to just save the whole contents of the disk and extract files
later.
