4-9] I'm having trouble writing a complete disc

(2002/08/16)

(This is for failures other than buffer underruns. For those, see
section (4-1) and perhaps section (4-4).)

If it's failing right as the disc is being finalized, and you're recording
in track-at-once mode, try recording in disc-at-once mode instead. It has
been suggested that some recorder+media combinations have trouble reading
the PMA (Program Memory Area, where a copy of the TOC is kept until the
disc is finalized) at the end of a write. With disc-at-once mode the
TOC is written early, so it doesn't have to get read out of the PMA.
See section (2-19) for the low-down on disc finalization.

When in doubt, check your ASPI layer. See section (4-44).

One user with an ATAPI recorder found that disabling DMA (from the Win98
peripheral properties) made things better.

Try letting the drive cool down (leave the machine off for a couple of
hours if you have an internal drive). Power up the machine and
immediately record the disc. Sometimes heat buildup can cause problems,
though this is less common with recent drives.


This was happening frequently with the HP4020i running off an AdvanSys SCSI
card under Win311 (i.e. WfWG). The solution here was to remove IFSHLP.SYS
from the CONFIG.SYS. (IFSHLP.SYS is somehow involved with 32-bit file
access and network support, so you may have to disable both of these before
disabling IFSHLP. You may have better luck under Win95.)

Another user with the same setup found that doing power-up diagnostics and
device reset right before burning the CD helped.
