Does anyone know of common faults with the CD Pro drives.
In particular, no read problems.
I have met a guy who has a stack of the drives with various faults.
I'm hoping to get a few.

we have boxes of them at work! from what the service guys tell me, the spindle motors go out and the lasers die are the two most common faults. other faults have to do with the plastic sled gear mounting system. some units the metal clip that holds the gear seems to be too tight causing the sled motor to die.
Overall, the CDpro mechs aren't very strong! There is a jukebox guy here in the USA that rebuilds the drives for a reasonable price! the ROWE and NSA jukeboxes are the main companies that use these drives. audiophile cd players are a 2nd to the jukebox guys!

To me, "CD-Pro" or "CD-Pro2" label applied to a CDM-12-based transport mech is a total oxymoron. To start with, none of these cdm12 units are even made by Philips, but, AFAIK, by Daisy Laser in China(did Philips even make the CDM-9?). The lasers, universally among them, are terribly unreliable, the sled drive could not have been designed more badly & unreliably, and the spindle motors in all but the brushless pro version are junk. I will never understand why anyone would spend more than $50 on a transport/player using this junk. I'd far rather rely upon the cheapest Sony laser/mech than the "best" of this lot.
Thanks for the replies, guys.
To be honest, I thought these were "top quality" drives but it appears not!
Or is it just that, in juke boxes, they get hammered?

Nope they are really not great drives...but what IS that's available today anyway?? as far as i know, Teac no longer makes there drive and pioneer no longer makes the stable platter system (correct me if i am incorrect in that statement) so what else is there that a company can buy??
The advantage that the CDpro units have is that it is a neat little packaged system, drive, controller, display, just add audio electronics and go! So it makes for an easy product for a company to build. all of the controller work has already been done. the drive itself offers I2S output, AES output that can be converted to SPDIF easily, it has an onboard D/A converter so you can output analog audio right off the drive! and if you add a connector it has a 16mhz master clock output!
The controller board has an IR sensor onboard that works with RC5 code, connections for LCD or VFD display, all the front panel button commands and sled/door switches etc, so you pretty much just apply power and go!

But why buy the "neat little package" if it's known to have a high failure rate?
Sony does still make their KSS-213-based transports, at the least, and it may not be 'pre-packaged', but does have well established & inexpensive chipset, and is vastly more reliable than the cdm12 junk, even when paired with the philips servo chipset that does not allow the laser to be more than a tiny bit off spec without trouble. Even the nearly 100%-economy-based Asian labels, except for mainly Shanling, have dumped the cdm12 junk in favor of the Sony. That, to me, is extremely telling.
Teac very definitely still makes cd-rom drives, which can't be less reliable than the cdm12's, and Pioneer currently does make bluray pc drives at least, which seem quite decent. I believe you are correct that the stable platter cd drive is history, sadly.
