Data Recovery and Data Protection!
Most of us have, at some point or other, accidentally
deleted a file which we've later regret! Most of the time
this isn't that big a deal because the deleted file can be
easily recreated or is still in the Windows Recycle Bin.
But what if you've deleted important files
which are not in the Recycle Bin (if they are too large or
deleted on a network drive, etc.)?
Last weekend I sat down to write a new article
for one of our clients. It was about re-installing Windows
XP and how to prepare for this, without losing data.
Normally I do a new install of the operating
system on a new hard drive, just to be 100% sure that I don't
loose any of my data and copy all the required files to the
new drive afterwards. Not this time, as I wanted to take the
risk in a real life scenario (I assume most users don't use
a new hard disk for what I was about to do).
I took one of our desktops used for
daily work and not for testing purposes. I copied all the
needed files on to the server for backup and inserted the
Windows installation CD, installed XP Pro and all the Updates,
which I downloaded from the Microsoft website. In total I
did this 4 times and formatted the hard disk twice during
this process.
Finally I found myself in a position
which I shouldn't be in, as the whole purpose of this job
was to write down exactly what to do to prevent loss of data.
I had a list of files, which I needed to back up, I saved
the folder with all the drivers for the machine and thought
that there was nothing missing. I ticked each one of the items
on my checklist to make sure that I hadn't forgotten anything.
I wish!
When I came to copy the Outlook PST
file back to the new installation, it had disappeared. For
some reason, this PST file "was not any longer" in my backup
folder. There was a file with the same icon, but it was too
small to be the PST file. I had been tricked. I'd copied the
wrong file and the actual PST file was gone. I couldn't believe
it! With all the care I had taken to make sure that nothing
went wrong - I could have kicked myself in the butt.
Frustrated with such a situation on
a Sunday evening I had one last hope - my GetDataBack CD.
I loaded the programme and started scanning my disk.
The chances seemed to be very small
as I defragment my machines regularly, and had formatted the
disk twice, but it was a last resort! I had very little hope
of finding the lost PST file again, at least unharmed. GetDataBack
showed 1 1/2 hours needed for the scan and we decided to get
out of the house to and left it running!
Back from a walk the scan was finished
and a lot of deleted files had been found. An almost unbelievable
amount of files actually. Hope was restored when I saw that
the PST file was under the deleted files with a chance of
recovery.
I was just a few mouse clicks away
from a happy ending, if the file was not corrupt!
And what do you know - it worked!
After installing Windows XP Pro 4 times,
and all the Windows Updates downloaded and installed 4 time,
and then formatting the hard disk TWICE and 1 installation
of Office 2003 Professional, the Outlook PST file was back
where it belonged. Unharmed and fully functional, my Sunday
evening was saved!
Summary:
You may have a good chance to recover
lost files. 'Deleted' does not mean gone from the disk.
My "experiment" shows that deleted
files remain on the hard disk and can be recovered, even after
plenty of read/write activities. This might not be of concern,
if you just use your computer for gaming, but for a business
machine it should concern you, as your PC, sold as a second
hand machine for some cash, can deliver your data, even if
it has been deleted. The only safe solution to deleting data
forever from you disk is by using software such as 'Secure
Wipe' just one of the utilities found in Microscope.
