BleepingComputer.com: Excessive Hardware Interrupts

Dell Optiplex GSX270 1gb RAM, 2.4gHz Processor, XP/PRO

I just installed a Maxtor 6L04032 40 GB secondary IDE Hard Drive to use for backup.
Formatted it to NTFS.
The backup Software (Acronis) estimated 1 hour 30 min or so to backup 14 Gig. This is way too long, and should only take 15 minutes, or less. (15 minutes on my other Dell 1.7 gHz machine. (Dell Dimension 4400)

When I looked at process explorer, the following resource was using 85 to 95% CPU.

Interrupts Hardware Interrupts & DPC - Showing 0k private and 0k working set.

Tried to update driver, but said I had the most recent one.

Any help is much appreciated.

Backed up files on DELL Dimension 4400 XP Home to two different drives. Ran a-ok
Used those same two disks in DELL Omniplex XP PRO - High % Interrupts both drives.

Thanks, looked thru the links you provided - way too over this head to be of value.

PS: I have tried two different drives in the Omniplex (XP PRO) with the same high Interrupt percentage.
Put them back in the DELL Dimension 4400 (XP Home) Run the same software to backup, and everything is fine.

Glad you resolved it .

I seldom have problems with backup/partition softwaare...but when I do, I just delete/uninstall and try it again after running checks on the hard drive/partitions.

Happy computing >

That was not a resolution. What I was saying is that when running those two drives, one at a time, on the XP Pro computer, the interrupt problem persisted. When I removed each of them and ran them on the XP Home computer they functioned ok.
But, the good news is that I did get the issue resolved on XP Pro Computer.

Not sure which of the following cured the Problem, but under the IDE\Atap\Atapi Controller there were duplicate entries for Primary, plus Secondary IDE channels, and Standard Dual channel PCI IDE Controller.
Someone suggested that wasn't correct, and to delete & reboot and new drivers would be installed.
I opted to only uninstall the duplicate entries for each.
At the IDE/Atap/Atapi controller level, I did a scan for hardware changes which added ATA Storage Controller.
After reboot the dupe primary & scdy were regenerated (I assume for the CD/RW device).
The duplicate Standard Dual channel PCI IDE Controller disappeared.
A new Ultra ATA Storage controller was added.
Drives are functioning ok now on the XP Pro Machine.
