 |

I recorded some data CDs 3 years ago, using Philips Multi Purpose
CDR-74 (650 MB). At the same time, I also made some other data CDs,
using Verbatim CDs. I used the same CD recorder (Sony CRX 1611, love
it), which I'm still using (still love it).
I have tested 3 of the Philips CDs recently, and all 3 had errors. I
did the test making a Nero CD-copy; Nero informs you of any unreadable
sector after cancelling the operation. On one CD I ran the test twice
and the bad sector that cancelled the operation was different than the
first one. This to me indicates not a scratched CD but rather a poor
CD-ROM reader.
It's somewhat againt the odd for all 3 CDs going bad, and temperature
and humidity have been normal these 3 years, no sunlight, hardly any
handling, I'm very careful regardless, and they're not written on.
And the 2 Verbatim CDs from the same time ran the test perfectly, and
they were stored together with the Philips, which to me suggests
problems reading a certain type of CD; again, a CD-ROM problem, not a
problem with the CDs.
Could the reading laser on my CD-ROM (Sony CRX 1611) have dimmed, and
it can't read the lower quality stuff anymore? And if so, am I
generating lower quality CDs by continuing to use my trusty old Sony to
record CDs? |

Your Phillips discs have gone bad, which they are well-known to do. Phillips
uses CDR's from the cheapest known sources, and they burn very poorly in
many drives. Rescue as much data as you can from them before they go
completely bad.
A new $25 drive may well be able to read them better than the old Sony, but
the discs are certainly dying.
Your Sony is no longer appropriate for newer high speed media, which is
designed for burning in high speed drives.
