If your cd-rom is old, then this can cause problems. My old 32x drive will only read a cd-R copied disk, try putting in a rewrite it can not see the disk.

It goes something like this, a factory produced cd-rom disk has its data stamp onto the disk, which has a reflective coating, this ceates hills and pits to repersent the data, and it cause the lazer beam to reflect back in a different way, depending on weather it hits a hill or a pit.

A cd-r also has a reflective surface, and the hills and pits that create the data is burn't into this surface, in a cd-rom it acts very much like a pressed cd-rom, so most cd-roms can pick up the beam being returned. So age of the crd-machine doesn't really effect it's ability to read data.

But cd-rw tend to use a dye that when heated changes colour, to repersent the hill and pits of data. this tends to lead to a slightly less reflective surface, so older drives can not pick up the flection as well, leading to the believe that no data is present.

And sometimes it could be that the drive just doesn't like the make of the cd-r or cd-rw disk, if this could be the case check your manual or makers web site and they should give more information of what media is compatiable.

Or

If you have a new drive reinstall the drivers for it, as these might of become corrupt, or even out of date.

hopefully these might give you some idea whats happening, as you haven't said what spec your machine is or that of your friends.

Sorry if I haven't explained myself very weel, ut I've just spent 6 hours trying to work out whay only half of my camping trailer lights would work, and where the fault was, a head spinner or what?

i have a great big box or imation coasters that i bought cheap.my drive only reads or writes to them if it feels like it.

if i pay a few pence more and buy a spindle of slightly more expensive discs this doesnt happen.

it took me two months to figure this out.

try a different brand maybe.

Some other uses for duff disk

String on cotton across the garden, makes a good cat/bird scarer.

Get the kids to draw pattern/pictures on them and make a mobile.

Or in my case I kept a stack by the computer, this is for when 'that bright idea I had' all gone to pot, they get flung across the room at great speed, mind you hubby isn't impressed with the dents that he's had to take out of the plaster. But the kids have now learn't to knock on the door before entering!

Sadly they don't make very good flower pots or ash tray, won't melt and ben very well!

try control panel/system/hardware/device manager/ and right click on the drive.choose uninstall then restart the computer and windows will detect it again and reinstall the drivers.

do bought discs work ok?


as above though if it only happens with cdrs/rws try a different brand.

Another use for duff CD's - one guy I used to work with used to save all the CD's he got in magazines and then hang them up on a Christmas tree outside in his garden. He said they looked very bright and sparkly when the light shone on them and it didn't matter if anyone tried to nick them.

Time for a new drive - they're very cheap.

It seams to be a problem this with new drives also, as I have found that some disc's that will not read on a modern fast drive, will read in my old computer Mitsumi 4 speed

I was going to suggest a drive/CD player cleaning disc. You can pick them up in loads of places now, got mind from Sainsbury's for about £10. Don't use the one's with liquids though, get one that has a little brush on the underside of the disc. It'll clean off any dust that may have settled on the laser.

I said I was... I then read DieSse's comment, you can pick a standard CD-ROM up for less than £20 click here you could even go for a DVD ROM for abour £25
