Drive very slow. Interrupts Time Placeholder?
I have three internal hard drives, listed below:
HD0 - SATA - WDC WD360GD-00FNA0 (Raptor 37GB) HD1 - IDE - Maxtor 6Y250P0 (250GB) HD2 - IDE - WDC WD1200JB-00EVA0 (120GB) When I copy files from my external USB2 hard drive to HD0 or HD2, it is really fast, and the processor is near idle. But when I do the exact same thing to HD1, it is VERY slow (like 100x slower), and the processor graph is maxed out. The strange thing is that while the task manager processor graph shows the activity (and heat starts building up to the point that the machine shuts down), the process list shows "system idle process" near 98%. But using TaskInfo (shareware), I determined that the "Interrupts Time Processor" process is the culprit.. it's at 100% during the file copy. Does anyone know what this is, and what I can do about it? The S.M.A.R.T stats on all drives (incl HD1) all check out as healthy.

(SATA0, SATA1, IDE1-master, IDE1-slave, IDE2-master, IDE2-slave) Are there any other IDE devices in your server? Do you know that manual says: Two 1-inch IDE, SATA (when available), or SCSI internal hard drives NOTE: Hard-drive bus types cannot be mixed. Both drives must use the same bus type. When I copy files from my external USB2 hard drive to HD0 or HD2, it is really fast, and the processor is near idle. But when I do the exact same thing to HD1, it is VERY slow (like 100x slower), and the processor graph is maxed out.

But using TaskInfo (shareware), I determined that the "Interrupts Time Processor" process is the culprit.. it's at 100% during the file copy. What is the interrupt assignment for SATA, IDE and USB devices? Does anyone know what this is, and what I can do about it? The S.M.A.R.T stats on all drives (incl HD1) all check out as healthy.
