100% processor load when copying/defragging

[rover825lover]

Hi,

One user was complaining about his computer being slow. I checked it out and on the first hand everything seemed ok.
When i looked at the backup logs, this machine takes 5-6 hours to backup, in stead of 2-3.
Its seems when the system is in some kind of disk activity the processor load is between 90-100%.
That is 1. when defragging with diskkeeper
2. when copying files from one disk to another
3. when a backup is made

The system:
1ghz pIII
intel vc820 mobo with latest bios/patches
256 mb (expensive) rimms
2* 30 gb 75gxp (on the same ide)
3dlabs oxygen videocard
generic network card
os: winnt 4 sp 6a

Oh and yeah i did activate dma under nt.

suggestions?

put the drives on seperate IDE channels and see what happens.

If SCSI's not an option and DMA is already enabled, after you try them on different IDE channels I would suggest using the default windows drivers for your ATA controller instead of the intel ones. I had a similar problem under 2k when using Intel's drivers for the 815's controller, but Win2k's native drivers use MUCH less CPU cycles. Good luck!
