SubRosaSoft is the developer of [[MacForensicsLab]] and several other [[OS X]] software titles including [[FileSalvage]], [[CopyCatX]], and [[VolumeWorks]]. Based in Union City, California. and founded in 2002 they specialize in privacy related and system utilities. Their design philosophy revolves around easy-to-use yet extremely powerful software. They have produced security, file and device management, home security, forensics, and data and device recovery.  Their users range from entry-level Mac users and hobbyists to system administrators, consultants, and forensics professionals.

'''ddrescue''' is a raw disk imaging tool that "copies data from one file or block device to another, trying hard to rescue data in case of read errors."  The application is developed as part of the GNU project and has written with UNIX/Linux in mind.

'''ddrescue''' and '''[[dd_rescue]]''' are completely different programs which share no development between them.  The two projects are not related in any way except that they both attempt to enhance the standard [[dd]] tool and coincidentally chose similar names for their new programs.

From the [[ddrescue]] info pages:
 
<blockquote>
 
GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors.<br><br>
 
  
Ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps.<br><br>
 
  
The basic operation of ddrescue is fully automatic. That is, you don't have to wait for an error, stop the program, read the log, run it in reverse mode, etc.<br><br>
+
= Consumer Products =
  
If you use the logfile feature of ddrescue, the data is rescued very efficiently (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.<br><br>
 
  
Automatic merging of backups: If you have two or more damaged copies of a file, cdrom, etc, and run ddrescue on all of them, one at a time, with the same output file, you will probably obtain a complete and error-free file. This is so because the probability of having damaged areas at the same places on different input files is very low. Using
 
the logfile, only the needed blocks are read from the second and successive copies.

The package 'ddrescue' actually is [[dd_rescue]], another dd-like program which does not maintain a recovery log.

aptitude install gddrescue

== Usage ==
+
[http://www.subrosasoft.com/OSXSoftware/index.php?main_page=product_info&cPath=200&products_id=7 CopyCatX] allows you to create exact duplicates of your hard drive, Apple iPod, or Mac OS X startup drive. [http://www.subrosasoft.com/OSXSoftware/index.php?main_page=product_info&cPath=200&products_id=7 CopyCatX] is the fastest way to duplicate devices in most formats on your Apple Macintosh computer.
  
First you copy as much data as possible, without retrying or splitting sectors:

The fastest software duplication system for Mac OS X. [http://www.subrosasoft.com/OSXSoftware/index.php?main_page=product_info&cPath=200&products_id=7 CopyCatX] is extremely fast. It works on drives that other systems cannot recover by using our proprietary resumable/fault tolerant algorithms.
<blockquote>
+
ddrescue --no-split /dev/hda1 /dev/hdb1 logfile
+
</blockquote>
+
  
Then you change over to raw device access and let it retry 3 times:
+
Backups include every single detail of the original including permissions, icons, placement, and content.
<blockquote>
+
modprobe raw<br>
+
raw /dev/raw/raw1 /dev/hda1<br>
+
ddrescue --max-retries=3 /dev/raw/raw1 /dev/hdb1 logfile
+
</blockquote>
+
  
If that fails you can try again (still using raw) but retrimmed, so it tries to reread full sectors:
+
Unlike most backup programs which copy file-by-file, [http://www.subrosasoft.com/OSXSoftware/index.php?main_page=product_info&cPath=200&products_id=7 CopyCatX] utilizes a method called device copying.

When duplicating a volume, [http://www.subrosasoft.com/OSXSoftware/index.php?main_page=product_info&cPath=200&products_id=7 CopyCatX] is smart enough to skip all the blank space of a drive during the copying process to further improve the speed.

But unlike expensive third party alternatives, you'll have plenty of space left over in case you need to recover data.
