Disk Commander Saves Wiped-Out Data
This tool can save you from the panic attack that can ensue when you say, "Oops … I deleted it again …"
"Oops" is the last word you want to utter when you're in the server room
or overhear when you're walking by a user's desk. Sometimes the "oops"
occurs when a hard drive goes belly-up. However, the "oops" most commonly
uttered is due to human error, which leads to the majority of downtime.
On the server side, one of the more common scenarios is the removal of
an unneeded partition, only to realize you deleted the wrong one. On the
workstation side, users routinely throw things into the recycle bin and
empty it -- only to realize, weeks later, they really needed the file entitled
"Corporate Initiatives 2002.doc."
Should you panic? Should you start your search for that backup tape?
Before doing either one of those things, consider breaking out Disk Commander
from Winternals Software.
Disk Commander has three modes to help recover wiped-out data. One method
loads right on top of a working Windows system. However, with this mode,
there's the risk of writing over the space of the deleted file, hindering
recoverability. The Windows mode is most useful if you strictly want to
recover data files. The Windows mode isn't capable of supporting volume

The program also includes a single-floppy DOS mode to quickly recover
a deleted volume. Also, this mode can recover data files, but the restored
files must be sent to an available (and undamaged) FAT partition. This
method doesn't support long file names.
Finally, Disk Commander offers a multiple-floppy (or bootable CD-ROM)
mode that loads like a Windows NT or Windows 2000 bootable CD-ROM. This
mode is ideal when the volumes and files that need recovery are on RAID
devices, but the volumes aren't natively viewable in DOS without special
drivers. This mode can load the special drivers then proceed to recover
files with their long file names intact.
The good news is that you get to choose which mode you need to use when
you need it. You're not "locked in" to a specific version when you buy
the software, so you needn't worry about only getting "one shot" at creating
the type of recovery software you desire.
The software was able to recover deleted volumes and files as advertised.
It was easily able to recover files and volumes when the volume was simply
deleted and no additional writes to the hard drive had been performed.
The product had a bit of trouble recovering files and volumes once additional
data was written to the hard drive or additional partitions were created
on top of the old ones; but there's nothing that a recovery utility can
do to prevent Windows from re-using sectors that contain deleted data.
With this in mind, how should this product fit into your backup and recovery
strategy? It's not a replacement for good backup hygiene, but it could
save the day if a critical file was consistently skipped during the backup
process, was accidentally excluded, or was just plain unrecoverable. Also,
since desktop systems are rarely backed up, this product could be the
second-to-last resort in recovering users' deleted files. The last resort
in these cases is biting the very expensive bullet by sending the user's
hard drive to a hardware data recovery center such as Ontrack (www.ontrack.com).
