 CD
and DVD repair vs. CD and DVD data recovery by copying it to a safe
place
There appears to be a
false notion out there that bad CDs and DVDs can still be fixed.
While in some cases CD
and DVD discs can be polished to remove scratches, with mixed results,
most of the problems home users experience are not related to
scratches, even though it is often suspected to be the cause of all
troubles.
Most problems occur
due to bad writes !
For instance when the writer has no good write strategy or laser power
setting for the particular media or when the media quality itself is
doubtful, e.g. garage-shop media, bad settings in the media's pre-recorded
information with regards to strategy and laser power, uneven dye
distribution over the surface, warped media, eccentricity issues, uneven
weight distribution in the media etc.
During a disc
finalization process for instance, usually sections on the very inside and
sections on the very outside of the disc need to be updated. Sections
that may be different in quality, with all sorts of issues as a result.
Therefore it is
crucial to understand that fixing / repairing CDs is not a good way
to assure that your data is safe ! It may buy some time, if it
worked, but when things went wrong, try not to keep working with that bad
disc, even if it is re-writable media, set your data safe as quick as
possible and if needed write it to a new disc. Get rid of the bad
disc.
With cost of media
these days that is simply the smartest thing to do.
When it comes to
recovering data from CD or DVD,
meaning copying / extracting the data from disc to a safe place (e.g. Hard
Disk),
IsoBuster is the
solution to your problems.
IsoBuster comes highly
recommended by Philips, HP, Adaptec, Roxio, Nero, Sonic, .. and is probably
the most popular CD/DVD Data recovery software available to date.
I know it sounds like
a sales pitch, and of course we like you to ultimately buy our
software, but take it from an expert who has your interest at heart, do
not rely on repairing a disc.
Use other software to recover if you don't trust us, but don't mess with
software that actually writes to your disc in an attempt to fix things.
It will likely only make it worse.
