Hi,
I have recently installed two WD20EARS drives and set them up in win7 pro as mirrored drives (software raid 1).
Yesterday i started transferring some data from an old WD6400AAKS drive to them and the window that pops up when you copy was saying around 90MB/s and i could hear the drives "whizzing" away.
Today, i come to do some more transfering and instead of 90MB/s i get 3.2MB/s and i can't hear the sound of busy drives. I reboot the computer and it's the same.
I then ran seatools short self test, smart check and short generic test and they were all fine. I then try to transfer again and i get 45MB/s.
I left it copying for a while and come back to copy some more and it's now down to 6MB/s.
I tried sending 1GB between the WD6400AAKS and my system drive that is a 1TB WD green and i get 6MB/s. I try sending data from the 1TB WD Green to the mirrored drives and i get 35MB/s.
These new 2TB green drives are quite noisy in that i can hear the parking of the heads. I have a hunch that my problem is to do with power saving because even though i'm transfering 10GB i can still hear the odd drive park.
Any ideas?
I'm probably going to use the widdle3 util from WD to adjust the drive parking but i'm not sure that's the real problem.
Thanks,
Tim
