UServe won't eject cd

Posted by: dis on 31 March 2012

Have a new UServe !!

So far so good, but error came up during ripping and now cd won't eject. Have tried power off on the US, but now tells me there is "no cd present"

Any suggestions ??

cheers

I had this happen once, try powering off for an hour. then press the front eject button. Also I believe on newer models of the Userve there is a small hole on the front case where you can insert a paper clip or similar to manually eject.

 

Good luck

If the Unit fails to rip a disc and it sticks in the drive:


If the disc remains in the drive for a long period of time (on average 10 minutes should be sufficient to rip 80 minute audio discs), then it is possible that the disc used has a defect – either physical damage, a mastering issue or has an aggressive copy protection scheme built in.

 

Some possible reasons:


Copy Protection: Most manufacturers’ CD/DVD drives have some capability to work around these deliberate errors on the disc, but there is a limit to what the drives can do. If you are finding only certain discs have this issue and the majority are fine, it is best that the affected disc should not be used in the player. The problem here is most discs do not display copy protection labels, so it is hard to know which may be affected.


Physical damage: The error correction routines used in drives have three main levels of algorithm. Most discs will have dust on them and the error correction will generally cope well with this. If fingerprints are on the data surface, this will usually mean the error correction has to work harder to obtain the original data. In the case of scratches the drive will try as much as possible to correct for this, but potentially can end up muting the audio briefly or in our case, telling the Naim software to skip the “damaged” track altogether. In this case, the ripping engine moves to the next tracks and finally ejects the disc when it has finished ripping. If a particular disc is causing issue, but the majority of rips are fine, it is suggested this disc should not be used in the player.


Disc eccentricity and vibration: CD Audio discs used to be made to a “red book” standard; it is fairly common knowledge that this is no longer the case. The disc itself can be made eccentrically, causing the unit to vibrate on ripping or even jam in the drive.


If damage to the disc is so bad that the drive cannot cope with this, the disc should be ejected eventually, but this is down to how bad the disc has been damaged or manufactured.


This has in some cases, been seen as the unit retaining the disc for long periods of time. If a particular disc is causing issue in this way, the disc should not be used in the player. In this case power the unit down correctly from the front panel and the disc should eject on the next power up. If the disc still does not eject, then try using the mechanical front panel ejection-hole method, by repeatedly inserting a paper-clip in to the hole (UnitiServe) or the eject lever behind the door flap on
other variants - with the unit switched off, until the disc is visible.

Success - disc out !

thanks all for your help - tried the disc on another player, and yes it has a glitch.

now back to the fun job of ripping my collection

thanks

Richard,

Interesting reply.  And I remember watching an episode of Tomorrow's World in the 1970s where Raymond Baxter jumped up and down on a CD and then payed it flawlessly in a newfangled CD player ! CD was originally marketed as virtually indestructible - unlike those fragile black vinyl discs !

I have been fortunate not to have had any problems with my ns01 1 gb version. Just out of curiosity I have tried to find the manual eject, but failed, no whole on the front for a paper clip, and nothing I can find when I flip open the metal in front of the draw itself.

Claus, this refers only to the Unitiserve which uses a slot-loading mech.  The NS01 uses a drawer so shouldn't have any issues of the disc getting stuck inside.

 

Paul, yes, I well remember the episode of TW.  Interestingly I have some discs that look like they've hosted an ice hockey game which play and rip perfectly and yet also some brand new and seemingly perfect discs that have errors and very often irrecoverable errors on them - usually on the last tracks.
