Okay, you asked for it! ;-)  I can only agree -- which is why I'm 
rather pissed off with this Dell 4100 running ME and Dell OEM ECDC 
4.02d with a Sony CRX140E CD-RW drive.  Been meaning to mention this 
for some time now, so here goes...

I can usually get two or three good burns each boot-up before it clags 
out again, invariably with the following errors:

T0100: I/O error (06/C5/00) - Write error - buffer underrun occurred
T0100: I/O error (06/C5/00) - Write error - buffer underrun occurred
T7127: TrackWriter error - Flush failed
T7118: TrackWriter error - Command retry failed

At the time the system decides the CD-R is stuffed it usually claims 
"97% complete" (sometimes even "99% complete").  But when you inspect 
the rejected CD-R it's clear it has only burnt a fraction of the 
available space (e.g. 3 to 5 mm track width of the full 32(?) mm).

I've had the problem with several different brands (=>7) and dye 
types, and it *may* be more common when making data CD copies than 
writing from HDD to CD-R.  (In the latter case I usually make a disk 
image first; but the "copy" does that too, having only one drive.)

Strangely enough (and now touching all wood in sight :) I've never had 
a problem with routine writing to CD-RWs and formatted CD-Rs using 
DirectCD 3.01d_D5 which came with the other Dell stuff, and I do this 
daily (but it's usually only 20 to 30 MB at a time as an XCOPY 
operation from a DOS window).

In the absence of other likely culprits, I'm tending to blame Windows 
ME (after all, it does get a lot of bad PR :) because I also have 
problems with Windows Explorer working like it's crawling through 
treacle after it's been used to list a few big directories (lots of 
files rather than space used) and if this behaviour is let go for some 
time (i.e.no reboot) it gets to the stage where screen windows take 
*ages* to close down, as though there is a lot of behind the scenes 
processing happening [no HDD activity though] or, perhaps, just some 
timeout waiting to happen.

As said, it seems to happen whenever I've been accessing lots of 
files; which includes copying, deleting, or simply just scrolling 
through a long directory list.  How many is "lots"?  Well occasional 
data directories have upwards of 2500 files, though nearly all would 
be less than 500 and most much less than that.  Backup CD-Rs would 
usually contain between 4000 and 12000 files.


Cheers, Phred.
