reported a TDK VeloCD that reliably reads pressed discs and audio burns (WAV) but fails on burned MP3/data discs; earlier replies from and correctly pointed at software and burn-method causes, but the pattern most often indicates either an unfinalized/multisession format or a drive/firmware compatibility problem. The following explains why and gives focused, safe checks (easy → invasive) to narrow it down.

Audio CDs (Red Book) are written as CD‑DA tracks, while MP3s and other files are written as data with an ISO/UDF filesystem; multisession or packet‑written discs that aren’t finalized can be invisible to some drives. See the multisession/finalize behavior and why an “open” session may not show up on all drives. (background: Audio CD / CD‑DA and multisession/finalize).

Practical troubleshooting (ordered):

  1. Inspect the problematic disc with the burner’s “Disc Info” / “Close session” / “Finalize” features and, if present, close the last session (many burning apps expose this). If the disc is packet‑written, re-burn as a single‑session ISO9660 data disc (no packet writing) and finalize. (See multisession/finalize notes above.)
  2. Burn a small test data CD (ISO9660, finalize, burn at a low speed such as 4×–8×) on the problem machine and on a known‑good PC; compare results. Low speed and finalizing maximize compatibility.
  3. Run the standard Windows drive checklist: verify the drive in BIOS, check Device Manager, uninstall/reinstall the drive and IDE/ATAPI controllers, and remove corrupted filter drivers only after backing up the registry (UpperFilters/LowerFilters). Follow Microsoft’s step‑by‑step guidance when editing the registry.

If the drive still fails to read finalized, simple ISO data discs that other PCs read, the laser/optics or firmware compatibility is likely at fault; try a lens‑cleaning disc, test other media brands, check the drive maker for firmware updates, and be prepared to replace the unit if hardware tests fail (older drives wear out). HP’s hardware guidance covers these hardware checks and replacement guidance.

Notes/cautions: always back up the registry before edits and avoid packet‑writing formats (e.g., DirectCD/Drag‑and‑drop) for discs intended for broad compatibility.

Sounds to me like you need to examine the software being used to burn such CDs, and assess if it is doing an adequate job. What software is being used? Are they being burnt in your PC or in another PC? Are the disks readable in a different PC?

Some clarification about precisely what is occurring would help us to help you.

I was using Nero and yes they can be read in other PC's. I'm not trying to burn cd's i cant even read previously burnt cd's. i backed up all my data files....and cant read any of the cd's. As well as my mp3 files. But it will read previously burnt wave files.

Try a different burning program such as Roxio or just use the windows burning program. i have used nero and encounterd many problems with it

just kind of a comment but you really should try a differnt program


hope this helps

do you have another cd drive of any sort or if you have a network you can share a cd drive then you can install a different program but also go into the drive's properties and make sure everything is set right

Hope this helps
