Data Rescue is a tool
for recovering lost Macintosh volumes. It recovers files and folders from crashed
hard disks, floppy disks, or removable cartridges.
Recovered data is saved to another medium, leaving the original disk untouched. Wildbits
claim that Data Rescue will not only find your data in situations where other tools
fail, but it will recover them in a much better condition, restoring icons, dates
and even folder hierarchy.
Data Rescue is not a utility for retrieving files that you have deleted. In one test,
I performed a scan of a volume, and then deleted a file and emptied the trash, and
I was still able to recover the file. However, that is only because it had been scanned
prior to the deletion, and the header information was available. In another test
I deleted a file and emptied the trash, and then performed a scan, and the file was
nowhere to be found.
Data Rescue presents you with a dialog containing all the volumes it could find on
your system, and allows you to choose a volume for recovery. After clicking on a
volume name, Data Rescue scans the volume to establish a file list. You have an option
to perform a full scan or a fast scan, and you can choose HSF (standard file format)
or HFS+ (extended file format). In my test, I choose a 19.5 gigabyte volume, HFS+,
and fast scan. Data Rescue took 3 minutes to perform the first scan (getting the
file list), and another 2 minutes to run the second scan (allocation scan). One problem
I noticed during the second scan is that the timer was not working properly. The
first scan provided a working timer that counted down from 3:30, but the second scan
displayed 200:00, and bounced between 200:00 and 202:59 during the entire scan (fortunately,
it only took 2 minutes, not 200 minutes).
Data Rescue then provides a list of all the root files and folders, and you can navigate
through the folders just like in the Finder. Clicking on a file, folder, or group
of files and folders, and then clicking on recover, grabs the data and places it
on another volume of your choosing. You would most likely use this utility on a volume
that is corrupted, so always choose a different volume to recover files to.
Because I choose "Fast Scan", after I clicked on the start button to being
the initial scan, I was given a warning dialog indicating that some files may be
skipped. Looking at the final results, I couldn't see any files that it missed, so
I assume that a full scan does a more refined search when the volume is corrupted.
Because my volume was not corrupted, there was no need for this level of detail.
Data Rescue also comes with some extras, such as reporting features from the Report
menu, and Expert menu for changing preferences and block allocation layouts, and
a Blocks menu for working with specific blocks of data. Version 3.0 has come along
to be quite simple and Mac-like, yet very effective.
Data Rescue is not a replacement for Norton Utilities, but it is an excellent utility
for recovering volumes, such as corrupted volumes and volumes that other utilities
are unable to access properly. It has a streamlined user interface, with a enough
features to categorize this utility as a great piece of shareware.
