So I bought this 1TB Caviar Black just under a month ago and have just started using it with Windows 7 as my second drive. It's installed and running just fine, but transfers speeds from my external to it are around just 1MB/s, while transferring the same files to just my desktop will go to about 27mb/s.
I'm not very keen when it comes to hard drives, but I should be able to answer any basic questions you may need to help me solve this (of course, if you're so kind to do so! )
I'm trying to use it to hold my media and games, but this transfer rate is incredibly slow. Thanks for any and all help ahead of time.
You did not mention, but i figure you're using USB for your external drive. So its the USB interface that is 1MB/s (which is right if the bandwidth is 12Mbps like USB 1.1).
So the problem is that you connected your external casing to a slow USB port, or that slow USB devices (keyboard/mouse) are connected to the same hub, forcing it to downgrade to 12Mbps speeds (1MB/s) instead of the 480Mbps (~40MB/s) USB 2.0 is able to deliver.
So try some other USB ports, connect directly to the motherboard USB ports without other devices on the same USB channel.
Seems sub was on the right track. The external drive was slowing down other ports during transfers, and even after changing USB Ports, it remained at weird transfer speeds (between 1mb/s and... 30 mb/s), but I got all my data on my new drive and the internal (the 1TB) seems to be running fine, everything loads just fine and my games play well off of it.
Thanks for the help. (Now that I feel like an idiot for not realizing this! =P)
Ok, I'm back. It seems the drive itself might be broken. I've swapped power connectors as well as changed SATA cables and it still transfers slow from my main drive to itself. First access shows a moderately high speed (30 to 40 MB/s) and then it just drops to 2 MB/s.
It's still under the 5-year warranty, so should I call WD and get it replaced?
