techie question
 

I bought a external hd , which the computer sees it , holds files fine but when its on the computer acts very sluggesh.

I have a 500 watt power supply my firewire /usb2 pci card is powered directly to the power supply and the os is xp.

A bigger powersupply doesn't make your drives go faster. How is the external drive connected; USB or FireWire ? You might also want to check out the Event Log to see if you are getting any read/hardware errors on the external drive when you are trying to access it.

You're using a PCI card?

My external drives are dogs. I'd use usb 2
