A couple of weeks ago I was copying cds, and noticed that the entire copying process was only taking 3-4 minutes per cd. Now, after reformatting my computer, my burner still shows that it is writing at 48x, however it is taking atleast 10 minutes to copy a single cd? Any solutions or ideas to what might be wrong?

For : a short diagnostic checklist and likely causes that fit the symptom you described and the replies from and .

Try these steps in order:

  • Check the burner software first: confirm the selected write speed, turn off "verify after burn" and any "simulation" options, and try a burn with another authoring program to rule out software settings or a buggy recorder driver.
  • Verify host throughput: in the OS device manager examine the optical drive/controller transfer mode (ensure the channel is not stuck in a low-transfer mode). Slow host-to-drive transfers are a common cause; see Direct memory access (DMA).
  • Inspect cabling and controller drivers: swap the IDE/SATA cable or try a different port/controller. If the drive is on a shared channel with another device, move it or change master/slave jumpers.
  • Test media and watch the burn log: use a known-good brand of blank disc and observe the burn log for buffer underruns, write speed drops, or retries. Buffer underruns and data-flow issues will show up there; see Buffer underrun.
  • Isolate hardware: boot from a clean live CD/USB or move the drive to another machine. If the same slow behavior appears on a different system, the drive or its power connection is the likely culprit.

If all else fails, the drive is probably failing and replacement is the fastest fix. The above focuses on separating software/host issues from hardware so the next step — repair or replace — is clear. For general background on burning behavior and how drives select speeds, see Optical disc authoring.

My drive did that and about a month later it died completely...

Generally some slow down over a period of time, wear on the laser. I had that problem once, but luckily it wasnt from the drive, I think it had something to do with Windows XP SP2, it also affects USB 2.0 is some ways. Check for firmware upgrades from the company's website, thats what helped me. If not check around for more ideas
