Thanks for the post, Rich, but I'm fairly certain that SP1 is not my
problem here. I have had SP1 installed for some time and with CD-R
working fine. I also have SP1 installed on an HP Pavilion with no
problems whatsoever. It writes to the CD-R in native XP mode just
great. Just this one machine has the problem.
Any other ideas would be greatly appreciated!

PS I had read this same post by you on just about every other CD-ROM
related problem here, but thanks anyway
| XP Service Pack 1 hoses CD-ROM and floppy-disk access
|
| By Brian Livingston
|
| Microsoft's launch of its new Windows Server 2003 line is just taking
place
| as I write this, and my readers are starting to send fascinating tips
about
| its secrets. But while I'm compiling a new batch of articles on that
| subject, the most interesting gotcha I've heard of this week involves
| Windows XP with Service Pack 1 installed.
|
| Jeffery Davidson, manager of information systems for the ATP Oil & Gas
| Corporation, sent in the following well-documented tale. Have a
listen:
|
| · "Last week, my company purchased two new Panasonic Toughbook
| laptops for some of our field personnel. I configured them with
Windows XP
| and Office XP, made sure that all of the patches and drivers were
installed,
| including XP Service Pack 1a, added all of the third-party software
they
| needed, and sent them out to the users.
|
| "The users both came back yesterday and complained that they couldn't
get
| the floppy drives to work. After duplicating the problem, I spoke to
| Panasonic's tech support, who told me that this was a problem with the
SP1
| installation. He referred me to Microsoft's Knowledge Base article
811839 --
| 'An I/O Device Error May Occur When You Access the Floppy Disk Drive
in
| Windows XP Service Pack 1.'
|
| "Apparently, the problem is caused by Windows dynamically changing the
| computer processor power state to a deeper idle state (from the C2
state to
| the C3 state).
|
| "To fix the problem. the article referred me to another KB article,
| 811840 -- 'How to Change the PromoteLimit Value for the Transition
from C2
| to C3 Power States.' This fix involved editing two strings of four
bytes in
| six binary keys in the registry, increasing the time that must elapse
from
| 100 milliseconds to 500 milliseconds before Windows XP promotes the
| processor from a C2 to a C3 power state.
|
| "When I changed the registry, the two laptops were able to access
their
| floppy drives successfully.
|
| "All well and good. Here's where I started to get concerned. Late last
week,
| one user who had a Compaq EVO D510 desktop machine suddenly started
| experiencing severe endless loop crashes. Unable to repair the
problem, I
| decided to wipe the drive and reinstall Windows XP.
|
| Initially, I was unable to restore the system from Compaq's restore
disks.
| The technical support folks at Compaq decided the problem was a bad
restore
| disk. I was able to manually install XP, and then manually install the
| hardware drives from the corrupt disk.
|
| "After the installation, I again installed ancillary programs and
downloaded
| patches, including XP Service Pack 1a. After SP1 was installed, I
began to
| experience problems with the CD-ROM drive intermittently not reading
data
| from the different CD-ROMs I was trying to install from.
|
| "The error message I would get was 'An I/O error has occurred while
| installing a file. This is usually caused by bad installation media or
a
| corrupt installation file.' I could either abort or retry. However,
retrying
| did nothing but repeat the error message.
|
| "I decided to search the Microsoft knowledge base for 'I/O Errors' and
| promptly saw the same KB articles I used yesterday to fix the laptops.
I
| decided to try the same thing on this desktop, even though I hadn't
| experienced problems with the floppy drive.
|
| "Surprisingly enough, it worked. But that's what bothers me. Why is XP
SP1
| causing these problems with different kinds of I/O operations? This
has now
| occurred on three out of the 60-odd machines I'm responsible for, so
it's
| widespread enough to want Microsoft to come up with a better solution
than
| manually editing several binary strings in the registry. For that
matter,
| I'd tell them myself, but they don't have a great feedback system, as
you
| probably know."
