90-100% CPU time by Hardware Interrupt
Hi...
My HDD is too slow. 2.5 MB/sec
I got Process Explorer anf find that Hardware Interrupt is taking 90-100% CPU time any time there is a HDD activity.
Environment:
Asus A8V-VM mothrboard,
AMD athlon 64 4000
1 GB mem
WD 320 GB hdd
Particion 0: Windows XP - hungarian
Particion 1: Windows XP - english
and for testing:
(Particion 2: Windows XP - Spare)
(Particion 3: Windows XP - Linux SUSE)
Using Roadkil's Disk Speed for testing the HDD speed.
Story so far:
I had happily my new system with two partition (hungarian and english XP)
Once it crashed while copied a DVD vith NERO 6
Since then the HDD slown down and CPU usage went up.
To find out what happend I made the followings:
- Uninstalled NERO
- Restarted in Safe Mode
- Stopped all stoppable services, programs with Task Manager/Process Explorer
- Disabled the USB in the BIOS
Made no difference.
- Took out the HDD and connected via USB to an other machine: 15 MB/s !!!
- Put back the HDD, innstalled Linux on it : Normal speed !!! (just copiing a 300 MB file, took 5 sec)
- Installing an other XP (Spare) Normal speed 15 MB/sec...
It looks that:
The HDD is OK
The IDE is OK
I guess there is something in the older XP installation create some extreme IRQ requests while access the HDD.
But... What ?
The question is not really just reinstaling XP....
Because it can happening again, so I would like your help to, find the rout of the problem.
Thank you in advance !!!
