Marantz cdr420 recorded media stored on harddrive.played back all fine unplugged now it says no valid files when i try to burn the disc but the drive reads full.

did you check the belts inside the mechanisum.?

Have you checked which CDR media the device can use.
This may be as simple as using a CD-R rather than a CD+R or vice versa,
Also check if you may be burning to a CDRW or CDR.

could be bad cd's ,but id say your recorder is going bad. you can try cd rw disks they work better in this case. then use a pc to copy to regular cd then reuse the cd rw disk again.

Hi,
It sounds like you haven't followed the last step to the burning procedure. All you need to do once you've completed burning your disc is to Finalize the disc. Read below why you need to finalize as well as the steps to follow in order to finalize the disc.
Hope this helps ;)
How to Finalize Finalizing is writing the TOC (table of contents) on a disc so a CD player can recognize the number of tracks, the total time for each track, and their location on the disc. A recorded disc must be finalized to playback on a standard CD player. Once finalized a CD-R disc can be played on CD players that support CD-R playback. CD-RW discs can only be played on CD players that support CD-RW playback. Consult your CD player owner's manual to confirm supported formats. Finalizing is necessary to: • be able to play a recorded CD-R or CD-RW disc on a CD player • prevent further recording on a disc • avoid erasing tracks on a CD-RW disc • record text information onto a disc you record Notes: • A finalized CD-R disc can never be recorded onto again. • A finalized CD-RW disc can be unfinalized for more recording. • The CDR300 can play back unfinalized CD-R or CD-RW discs. • SYNC REC+FINAL mode automatically finalizes.
Here are the steps in order to Finalize your disk
1 Push Stop. The display shows the number of tracks and their total playing time. 2 Push FINALIZE. FINALIZE is displayed for about 3 seconds.

Depends on your PC and its audio capabilities.

It has analog line I/O, and SPDIF digital I/O, and USB 2.0, allowing you to connect the CDR420 to virtually anything in the world.

You cannot burn audio CDs from MP3 files. You have to burn MP3 files as a data CD and not as an audio CD. See excerpt taken from page 33 in the CDR420 user guide. "Prepares CDs that can be played on standard CD players. Compact Disc Digital Audio (CDDA) uses uncompressed PCM, .wav files. The CDR420 does not convert MP3 files to PCM so MP3 files are ignored if you choose AUDIO as the CD TYPE"

Hi, i have located the manual for this device. you can access it and, print it out as well if you choose. the link to your manual is below.
