The Passa Man

I know i have already posted this, but no one replied, so I am giving this
one more go.

My laptop (Sony PCG-R505R/GK), its the one with the media slice at the
bottom has decided it only wants to read industry standard cds and dvd's. It
will not recognise any cdr even though its a combo drive. I have used an air
duster to clean but still no reaction. It will read standard DVD'd and all
genuine software vendor cds!!!!????

What is the problem? Can anyone help?

TIA

When you say it won't read cdr's are ones burnt by yourself? Have you tried
another cdr made by someone else's PC in your machine? Also try the cdr's
you are trying to use in someone else's machine. If they all work, then it
sounds like the drive may be going tits up.

Try on here,
alt.comp.periphs.cdr
You may need to update/change the firmware.
HTH :)

This drive dates from 1999? and the 505 was originally a Win98 computer?
Do you have actual experience that the drive will read CD-R? Even some
CD-R drives cannot necessarily read all recordable CDs and if a CD was
written at more than 1x-2x I would not necessarily expect that drive to
be able to read it given its age. Were you reading UDF CDRW (packet)
CDs and do not have the UDF reader anymore? I have two older computers
that will/will not read recordable CDs depending on the write speed and
the type of medium. and will absolutely not read any CD written at more
than 2x.

Didn't like to comment. But older CDs tend not to read CDR's, especially the
one on my laptop! What a pain:-(

Hi,
My understanding is the laser beam intensity is different between newer
drive and older ones. Some times it's worthwhile experimenting with
different brand blanks. I like black ones.

My thoughts entirely. The laser is the problem, so nothing can be done,
unless you experiment! OR change the CD reader!

Problem was the expense. As my laptop is 4 years old, I don't want to pay
through the nose for a fresh CD Reader. Knowing my luck the MoBo would go
t*ts up as soon as I replaced the CD reader.

No he does not! Read the other posts.

Most drives, even VERY old ones, can read CD-Rs just fine, providing
they're not higher than 650MB capacity, and even then they can usually
read most of the higher capacity. A 4 year old laptop should have no
problems with CD-Rs unless the drive was flaky to begin with, marginal for
any use at all.

Differences reading different burn speeds suggests a problem with the
burner or media, not the reader.

If that's the case, I must have been unlucky! My first reader wouldn't read
cd-r, Also a brand new one of the same model won't. Teac, BTW.
If you search newsgroups there is plenty of complaints about this. I'd guess
it's the older lasers that are not up to the job.

As someone suggest, I'll try a burnt CD at a low speed to see if there is a
difference and use differing media.

Hi,
Also always use latest firmware for the drive if there is one.

The CD Reader doesn't have any firmware update. I've tried finding some but
there is none.

Just run a CD off using the slowest writing speed on another machine [1.5
hours it took:-] And it works! in my laptop.

Another thing - as Passa Man doesn't seem to be around to read his replies
(and also stated no-one replied to his earlier post - so he obviously failed
to read my reply):
I have *exactly* the same problem - it's *not* firmware related - it's *not*
an old drive (less than 12 months in my case) and I suspect, as with my
drive, his drive previously read CDR's fine - it just seemed to gradually
develop this fault - at first I thought it was only with CD's burned with my
external Sony Firewire DVD +/- CDRW - so thought it was maybe a speed issue.
But mine certainly has developed an aversion to CDR's even written at
moderate speeds by the Drive itself!
All these points negate much of what has been conjectured here.
Any other ideas anyone?
