OPTICAL STORAGE TECHNOLOGY ASSOCIATION PROVIDES TIPS TO SAVE TREASURED FAMILY PHOTO MEMORIES
Digital Photos stored on CDs and DVDs caught in
flood waters may be recoverable.
CUPERTINO, Calif., Sept. 20, 2005 — If a disaster is on your doorstep,
what will you do? Whether it is an impending hurricane, tornado, fire
or response to an earthquake, the most immediate reaction is to grab
your kids, pets and the family photo album and leave the area of danger.
However, today’s precious family memories are not necessarily stored
as prints in a bulky album or a box, but are often on a computer hard
drive, or, even better, on more portable CDs or DVDs. People just may
not be able to take the time to disconnect the computer and tote it out
of the house when getting safely out of harms way may only give you minutes
The Optical Storage Technology Association (OSTA) has been pondering
just such a scenario. First of all, OSTA wants to encourage people contemplating
their own disaster preparedness plans to make sure that backing up their
photos and data to easily portable CD or DVD discs is near the top of
their preparation list. Of the hundreds of thousands of people caught
in the turmoil of the recent hurricane, how many of them left behind
family memories in the form of digital photos stored in their computer
that may be submerged under the flood waters or debris? And an even bigger
question – how many of those pictures will be retrievable? However,
for those flood victims who did have photos on CDs or DVDs, but were
unable to take them with them, don’t toss them out just because
they are wet and dirty – saving those images may be as simple as
a little mild detergent and water and drying with a soft cloth, provided
the discs are not warped or broken.
Backing up to CDs and DVDs is probably the simplest and most effective
insurance for protecting data, photos, and videos,” said David
Bunzel, OSTA president. “While many kinds of data can be reconstructed
from other sources, precious memories captured as digital photos are
especially important to back up. Today, recordable CD and DVD media are
very affordable and
easy-to-use backup software programs are readily available to make this
a relatively simple task for many computer users. Best practices for
safeguarding very important data or images would also include making
duplicate set of CDs or DVDs and storing them in a separate location.”
Preliminary submersion tests conducted by the National Institute of Standards
and Technology have provided some encouraging news,” said Fred
Byers, IT specialist for NIST. “Although it is a small, preliminary
sample, we found that recordable CDs submerged in water for 24, 63 and
71 hours could be read after they were allowed to dry thoroughly.”
The Photo Marketing Association has forecast that approximately 20 billion
digital images will be taken in 2005, and nearly 65%, or more than 12
billion images, will not be printed but will be stored in digital format.
For images stored on CDs and DVDs, and not on the computer’s hard
drive, recovery may be easier than you think.
OSTA has some tips on how to clean and recover data and images from those
CDs and DVDs, provided by member companies that manufacturer optical
drives or media, including Fujifilm, Imation, Maxell, Memorex, Sony Electronics,
TDK, and Verbatim.
Tips for Cleaning Wet or Damaged CDs or DVDs
Handle discs carefully by the edges only.
- Inspect the surface of the disc for damage or contamination,
to see if it needs to be cleaned. Canned compressed air is excellent
- If needed, rinse carefully in clean, warm water to remove any
grit that could cause scratches when the disc is wiped.
- If any debris or film remains that needs to be removed, clean
gently with warm water and a mild detergent (e.g., dish-washing
eyeglass cleaning solution, isopropyl alcohol or a commercially
available CD/DVD cleaning solution.
- Gently wipe dry with a lint-free, soft cotton cloth. Use a wiping
motion moving from the center of the disc to the outside edge instead
of wiping around the disc. If wiping does cause any scratch, an “inside
to outside” scratch will cut across the data tracks around
the disc instead of running along them and damaging additional
- If any residue or film remains, wipe with alcohol and a soft
- Remember to clean the case, too.
- If a disc is still damp, store upright (on edge) to allow
to air dry.
- Insert thoroughly dry disc in appropriate disc drive to attempt
to read data. If the disc isn’t readable, try a different
disc drive. Different drives have different optical qualities with
of error correction ability.
- Data on the majority of discs is likely to be readable after
following these steps. For those discs that still cannot be read,
information on disc handling and data recovery is available on
in the data handling, storage and disposal sections of two white
papers on recordable CDs and DVDs. For the applicable section in “Understanding
CD-R and CD-RW” go to http://www.osta.org/technology/cdqa12.htm.

About the Optical Storage Technology Association (OSTA)
The Optical Storage Technology Association (OSTA) was incorporated as
an international trade association in 1992 to promote the use of recordable
optical technologies and products. The organization’s membership
includes optical product manufacturers and resellers from three continents,
representing more than 85 percent of worldwide writable optical product
shipments. They work to shape the future of the industry through regular
meetings of DVD Compatibility, Commercial Optical Storage Applications
(COSA), Marketing, MPV (MusicPhotoVideo), Planning and UDF committees.
