I/O Device Error.............HELP....

[scootersite]

When I try to copy files to another computer or to a back up drive
attached through a USB port I keep getting the error message "The
request could not be performed because of an I/O Device error". I've
tried splitting up the files, rarring them, renaming them and
everything I could think of but nothing works. When I split the files
into smaller segments there's always a one or two of the smaller files
that will still cause this error so I can't copy the complete files.
I've done the disk-check and that didn't help. It mostly happens with
large files (over 100 MBS) but occasionally even smaller files will
not copy. This is a real problem as I have allot of large video files
that I can't back up. I run XPHome and this has just started happening
over the last month.
Any other suggestions....please?

First - is the I/O error being logged against the source drive or the
destination drive ? Second is the USB a High (1-1.1) or Full Speed
port (2.0) ?
External USB drives internally use a traditional PATA or IDE drive
and have a chip that converts data to a Serial form. This is why a
USB 2.0 complaint drive will only transfer data at around 26 Meg
a second. (Forget the theoretical maximum of 480 Megabytes)
Externals may have this problem if their policy is set to "Optimize
for Performance" - that enables their Write behind caches. I would
check Device Manager, Disk Drives, Advanced (TAB) and see
how your external drive polices are set. You can also benchmark
your drives ( Access Time, Burst & Sustained) with a small program
called DiskSpeed32:

I'm not sure how you tell which device the error is being logged to,
but I assume it's against my main drive since I get this error when
trying to copy files from my C drive to 3 other computers as well as
my external drive. My USB port is a standard 1 speed, but again I
don't think that's the problem because I get this error no matter
where I'm copying to.

You can determine the source of the errors by using Event Viewer.
Click Start, Run (Type) Eventvwr.Msc [Enter]
Errors will be shown as Red Icons in descending chronological order.
Double-Clicking an entry will bring up a details box with a numerical
Event ID # and a brief description.

If it happens on every type of transfer, then you need to look to the
primary Mass Storage controller as the source. I would check the
IDE controller (If that's what is used) and see what operating mode
your hard drive is running under. It should be a UDMA mode 3 or
greater. If it's set to PIO mode, then XP has done a mode roll back.
This happens when XP logs errors against a controller and in a effort
to stop the errors, lowers the operating mode back to a slower
speed.

First off, I appreciate you taking the time to help me and secondly
I'm not especially computer literate so some of your suggestions are
foreign to me. I did the Eventvwr check and it's saying the source is
"Service Control Manager". When I go to the knowledge base that it
directs me to it tells me there is no information in the base
regarding this problem.
Could you point me to where I might check the mode for the Mass
Storage Controller as you suggested? I'm in Device Manager but I'm not
seeing that.
Thanks Again.

It also says "An error was detected on device\Device\Harddisk4\D
during a paging operation" if that's any help

Sorry - Responders can only infer the poster's knowledge and
experience. Because of that we sometimes provide too much or
too little details. Sometimes we get lazy/forget to provide some
of the important details.

To check your device's operating mode go to Device Manager
and expand the IDE/ATAPI controller category. Double-Click
the Primary IDE. There should be an Advanced (TAB) on it will
be the operating mode of the Master/Slave devices. Repeat this
for the Secondary controller. If you find that your disk drive is set
to PIO mode then the fix is to 1st, Uninstall the Drive in the disk
category and then go back to IDE/ATAPI and uninstall both the
Secondary and Primary controllers. Reboot and XP will re-find
or enumerate the controllers and their devices.
NOTE: Most all CD/DVD devices used UDMA mode 2. Disk
drives should appear as modes 3,4 or 5

There are no advanced tabs in either the controller or disk categories
and I could not find anything indicating the mode. For what it's worth
the dialog box tells me that the drives and comptrollers are working
properly with no conflicts. As far as un installing drives and
controllers......I'm afraid that's out of my league. I've never
attempted anything like that and I'd be afraid that I'd loose my
computer completely.
Not sure if this helps you but the warning message being logged into
Event Manager for these failures is "An error was detected on
device\Device\Harddisk4\D during a paging operation".
Again, thanx
