CD question

[William R. Walsh]

Hi!

Exactly - well made CD players tend to be very reliable as far as lasers
go
(more reliable than lasers in DVD players or CD-ROM drives), I've got a
first generation Philips CD101 that still plays fine after 25 years (even
on CD-R's but obviously won't read RW's).

Sitting not three feet away from me is a Kyocera DA-610 player. In its day
it was high end--gold plated connectors and very good build quality
throughout. Made sometime in 1985...it still plays well today although the
odd disc or track sometimes won't play without a bit of encouragement
(usually cycling the tray or going back to another track).

Actually there's a thought - don't suppose the schools are trying to save
cash and using CD-RW's to allow re-use of discs and the players don't
officially support them but allow the occasional disc to play anyway (some
old players may have borderline ability to read CD-RW's even though not
designed to) so when one doesn't they assume it's a fault?

I wondered about that. A number of older players that I have will attempt to
play a CD-RW with varying degrees of success. Some of them are even
temperature sensitive! The oldest player I presently have that can play
CD-RW discs reliably all of the time is a very early Philips/LMS 1X CD-ROM
that came with a PC soundcard. It still amazes me that it can do so, but it
does.

On a few occasions I've "ripped" a troublesome disc, and then burned a
replacement CD-R. The replacements play fine on all of the CD players
we've tried. The ripping of these damaged discs often takes a very
long time... the drive and software end up retrying certain sections
of the disc dozens of times in order to reconstruct the data correctly.

What software did you use to rip the damaged disks?
I ask because my young son has managed to scratch up a bunch of his
mother's favourite CDs & DVDs, so I'd like to recover them.

Since I use Linux, I used the de-facto standard: "cdparanoia". This
is available both as a standalone ripper, and as a library which is
incorporated into GUI packages such as GRip.

If I were to do it on Windows, I'd probably use Exact Audio Copy,
which I understand does much the same thing.

Thanks for the info, Dave. Do you know of any similar programs that work
on DVDs?

In my (limited) experience the best is CDPARANOIA for Linux,

http://www.xiph.org/paranoia/

I think it is used by several GUI packages.

If you have a Mac and use Mac Ports, then you can install it there, but that's
a very long way to get a program if you only want one port.

There are GUI's for the Mac for it too, and possibly for Windows.

Geoff.

Thanks, Geoff.

Nothing terribly specific, I'm afraid. The closest thing I can think
of (again, for Linux or *BSD or Unix) is the GNU "ddrescue" data
recovery tool.

Ripping damaged DVDs and transferring their contents to DVD-R is going
to be made extra-tricky by the presence of encryption. If the data is
simply burned to DVD-R, it'll be unplayable. In order to actually
recover a commercial DVD to playability you'll have to use software
which figures out the encryption coding and removes it... and doing so
is a likely violation of the Digital Millenium Copyright Act (which
sits right behind "no jaywalking" as one of the most frequently
scoffed-at laws in the U.S.)

I do _not_ wish to receive unsolicited commercial email, and I will
boycott any company which has the gall to send me such ads!

All the flavors of linux I've used and use have libs for CSS
decryption. Problem is there are several different additional
copyright protection schemes that can be and are used. However
CSS is the first that needs to go just to even read the disc.



And by the wat it's just as much of a criminal activity to rip a CD.

I have an OLD Technics CD player circa 1985 that will play a factory
CD even if you dipped it in mud but under no circumstances will it
play any CDR.

CDROM for a PC has always been a different beast.

Thanks Geoff, I'll give it a try.
