Hiya,

My stereo packed up recently. Luckily I had another one so I started using that. The sound is amazing. Put '7 For Old England' in – nothing happened. It didn't even do that searching thing it does when I put a cd in.

I checked said cd; it looked OK. I tried to get it to work 3 times with nothing. Others play fine, including ones I've made myself – I frantically made a copy, which is fine.

The stereo's a Panasonic if that helps. It would be a Maddy Prior cd that didn't work, wouldn't it ??

Have you had any problems with certain cds not working but others being fine ??

Yes.

Usually a scratch along what would be a groove if it were an LP.

Copying in computer can have multiple goes at finding the missing bits and produce a good copy.

It happens repeatedly with my Bluehorses CDs and my Jon Loomes CD and one of my Brian Peters CDs so I have multiple copies of them some of which work in one car and some in another.

If the machine doesn't even search, there is usually a problem near the centre of the CD - the index is there. Players start from the centre and play outwards. Have a close look for scratches, dirt or rainbow patterns that indicate decaying aluminium coating.

It can be mastering issues disagreeing with a particular model of CD player - not long ago a guest proudly brought their brand new CD into the studio to do an on-air launch, and it wouldn't register or play... so I stuck it in the duplicator and the copy played fine.

No, this is not a homemade CD, it is commercially produced - and not one original we've tried will work in the Denon players, yet a CDR copy plays perfectly.

Just got a new banjo CD and it wouldn't play on either the computer or the CD player. Stuck it in the freezer inside a sealed plastic bag for a couple of ours and it worked fine in both.

I've had a couple of CDs that partly lose the silvering. It blisters or peels off. Since that is the recording surface, errors can be expected.

The first one appeared to be a professional recording, but turned out to be an artist's private effort. I picked at the blister, and finally was left with a transparent disk!

That's why I refuse to use stick-on labels! Ink-jet printable CDs are much better.
