During the last years, I lost many times data from CDs, completely or
partially. The CDs were never phisically damaged in some way. Simply, data
were lost, like there were lost from magnetic disks. What is a possible
cause?Thanks,Paul
 
It could be something to do with your CD burning program - you could try a
new one - there are plenty of free ones that work well out there.

Or maybe you just need to do something simple like reduce your burning speed
- sometimes if the burning speed is too high it can corrupt data.

If the disk was burned proper, the data will be there even if you don't see
it.

Did you get burn errors....?
What type of data are you burning..?

Need to find out if it is a burn problem or a find the data problem.

The only possible cause I can think of, short of subsequent damage to
the CD, would have been a bad or incomplete initial "burn," to start with.

Believe it or not, CDs are written optically. Unlike any other storage media,
if taken proper care of, they can outlast any other storage device you can
think of (such as a hard drive).

Were they left out in the light? CDs will degrade if left in the
light; they should be stored in darkness. Also, try burning your CDs
at lower rates.

I don't believe it. Commercial / Retail CDs are pressed, they are not
written to. CD and DVD drives use a laser to burn data. CDs and DVDs are
read optically.

Can you give some specifics? How were these CD's burned? What program,
what hardware? What format? CD-R, CD-RW, etc. How did you determine they
lost data? Were the CD's inspected on the same computer with the same
hardware?
 
Thanks for yr message.
CDs (CD-R) were burned with Nero start smart. Sony DVD RW. WinXP home, sp2,
pentium 4, 3,2GHz, 1 GB Ram. I always check CDs after burning.After that I am
progressivery loosing data after some time.Not from all CDs though...
Lately I am using these Black disks, but same results.

Try playing the CD's on a different drive.
Some drives crap out.

CD-RW disks made with InCD or packet writing software may not reproduce on
another drive or computer.

Actually I learned this either from my computer engineering teacher or from
an online computer course while in his class. Other media is magnetic and CDs
have "grooves" in it that are readable binary for the computer.
 
I heard somewhere which may be an unreliable source, but what I heard was
that Nero comes with spyware. Other than that, I doubt that it would give you
bad quality as to the CD. Try copying the CD contents to the hard drive and
try it again.

I don't know. Use a different burning program, different media, different
burn speed. Change the CD drive. Data shouldn't be disappearing from a
properly burned CD-R.
 
Nero does not come with any spyware. Whatever you heard, you either heard
wrong or the informer hasn't got a clue as to what they're talking about.
I've used it and other burning programs for years without issue.

Care to share that, or do you want to leave everyone in suspense?

"Groves??!!" I hope you didn't pay for that class.

1. CDs should be burned at lower speeds
2. Another problem was our graphic design folders, with subfolders packed with
layers and channels and heavy graphic files, which it seems, made in certain
cases the CDs unreadable. I experimented with a better file organizing, and
found a trouble free CD reading.Thanks,Paul
