Roger, you could try this:

I have not tried it myself so can give no recommendation.

Good luck.

often had problems reading CDs which were cured by using a different PC. i think there can be problems with tracking accuracy.

If the CD

is a RW it can only be read by a PC which either has a RW reader or it has the U-files.

The latter (if for Roxio EasyCD) can be downloaded from the Roxio site.

Try using a new cd rom. I have often found that older cd roms are not very reliable reading home made cds. Try burning a copy (long shot).

Tip for the future Don't use rewritable CD to store data pics etc as they are not as reliable as the burn once type. Also for reliable backups burn at least 2 cds.

Here is an interseting page on the subject

Sorry can't be more help

The Life span of a CD is surprisingly small. Sounds like you have some CD's starting to degrade. I know we were all sold CD's on the premise that they would last forever. But it's simply not true. Every CD I have seen that is 10 years old show some kind of degradation. Audio CD's kept in the home can have degradation but still play. The player skips the errors and we can't hear the difference until it gets really bad. Data CD's show degradation much more readily, because one error on the disc can result in a program/data failure. On top of all that, CD's kept on a damp boat will degrade even faster as will CD's created on a home burner that is of a lesser quality than very expensive commercial ones.

My advice is this. Wherever data is very important, keep it on a hard drive. Hard drives are cheap these days. Also as new data storage technologies become available move your data on to them.

A recent survey by the Dutch magazine PC-Active on 30 brands of CDR has shown the life expectancy to be only 20 months!! However some of the better branded CDR's have done a lot better.

Type CD degradation into your search engine. There are many forums discussing this.

Roger, have a look at the surface of the CD. Is it scratched, or are any areas of different colour?

There was a thread a while back on CD/DVD viability as long term storage you might want to read to give some perspective

Hi Brendan
the disc does have very light scratches.
no different colours.
but the disc has been recorded in 2 distinct sectors with a small band of approx 1m/m ( of un-recorded disc ) in between.
the disc is recorded out to about 1/2 disc width

Scratches on the surface can have a huge impact. There are devices available to take these off. Might be worth trying as a last resort if you've tried other CD players first, and these also cannot read the disc. A one or twice off option only though, as they cut through the surface (like over sanding teak) eventually

thanks
am i safe to "close" this disc to enable reading on any drive

There is no protocol that necessarily gives access to any CD player, it depends on the format of the player/writer you have, and the software you used to burn it. Some info on this would help.

LG Roxio 5 running an LG re-writer.
i can read what i think is "part of the disc" every time, the system scan-disc tells me there is a problem but cant fix it. i cant "close " the disc either.
i have formatted another disc to drag-drop & that works fine & would "close" if required.
i have copied all the photos that were accessable, assume there r more
