157713 2003-07-06 03:35:00 Have you tried using different media brands? I know stand alone DVD players are sensitive to the type of media used so I wonder if that holds true for CD Writers. It's probably more complicated than that as I've tried all sorts of CDR types in my writer and havent had a problem yet - touchwood. parry (27)
157714 2003-07-06 04:30:00 It's a combination of factors. All writable media are grossly outside the reflectivity standards for CDs. :D The ratio between "pit/land" is enough, usually, and the lasers have been boosted up a bit in more modern drives (that's why a lot of older drives (audio and digital) won't see "written" CDs but can read "pressed" ones.

The original poster's problem is most likely a laser with low output and scratched/dirty CDs. I had a problem with a magazine software CD yesterday: close examination showed that the disk looked to be "freckled". There were uniformly spaced "dots" all over the surface, and I had to give up. I haven't got a vacuum aluminising plant to recoat it. :-(

157715 2003-07-06 04:48:00 Sounds like a classic "copy protection problem" to me.

Microsoft have released a patch for XP to address a Safedisc copy protection problem in XP itelf. Search the MS site for that and try that.

Some CD drives have hassles reading round copy protection on discs and this can be solved by upgrading the "firmware" of the CD drive. However it can be difficult to find the exact right firmware (try the manufacturers site or do a search for CD firmware online) and if you get it wrong it is like a failed BIOS flash...terminal.

Usually I find that a new CD drive will fix it as a last resort.

157716 2003-07-06 05:57:00 If you can't find out who made your cd-rom drive, you will need to get inside your PC, unscrew the cdrom, pull it out a little, and read the manufacturers sticker on it. That will tell you who made it, and a website to go to usually.

For the firmware, read through all the text that shows up when you boot your computer. Next to your cd-rom drive it should say the firmware it has.

Not quite true... my Asus 48X writes happily at 4X on music compilations, and with CDRW discs, can write at 1X too.

Also, a newer CD-Writer able to write at 1X is the Yamaha CRW-F1 (www.yamaha.co.jp). I think it even has a music "mastering" option which allows a deeper, wider burn of data to the disc which removes a lot of the jitter error problems some older audio CD players suffered from.

Lo.

157719 2003-07-07 12:06:00 BTW I mentioned my problem to one of my geek friends at work today, and he was telling me that he had this problem with his home stereo .

The serviceman said he had seen this before in that brand of stereo and fixed it by upping the voltage from . 5v to 3v . No more troubles .

Do you recommend trying this on a computer, and if I was to try it, how would I do it?
