Why would an external eSata Drive (xSonic with 500Gb notebook Hard Drive) run ok on a Silicon Image based PCI-E to eSata adaptor at about 35MB/s, But then run really slow when plugged into NForce4 Sata socket via cable?
I have another version of the problem with Really slow 1MB/s!!! performance on a ASUS P5K Pro Motherboard with E8400 CPU. This time the same card is plugged into a PCI-E socket.
The same eSata drive is plugged into the Esata port on the card.
All this is running on Windows XP Pro 32bit.
Any suggestions on how to diagnose the problems??
