Ok im having weird issues with my External HDD. First ill explain the Hardware. The external HDD is a WD 1TB Black (month old) in a ASTONE 481E enclosure which has e-sata and USB. It is connected to a e-sata connector at the back of my computer that plugs into a spare sata port on the motherboard. This is all got to do with my current machine <. Now the thing is its running very slow when i connect the e-sata external HDD. I mean VERY slow, slower then USB, and it slows down the whole computer, and ive noticed that it is using close to 100% of the CPU and i have no idea why this is happening. (doesn't show in Task manager) Anyway USB seems to run fine and i have also tested this out on the SLi computer< and it runs fine with e-sata, so im stumped. It used to run fine on mine to but then one day it went wrong If anyone has any ideas on why this is happening that would be great, id love to be able to use my e-sata on this computer again.
