when I start a large directory copy (a few gigs) the speed kde reports is 40-50MB/s.....this quickly drops to 30-70KB/s. Is this incorrectly reported or is there some setting that needs tweaking? hdparm settings are checked dma on 32 bit maxsectrns at 16(drive max) 2.6.11 controller is a NForce2 ata drives are WD ata100(on same channel) w/8MB cache
