Hi I have a Western Digital 1.5tb AV-GP hard drive as a backup drive. A quick format takes 1 hour wher as on the Samsung only seconds. Using USB 3.0 I transferred 600gb to the samsung in approx 3 hours at 51mb/s. Trying to do the same on the western digital says will take 27days and speed is 112kb/s. Tried copying hard rive to hard dive and the same result maximum transfer 117kb/s. Tried with standard windows file copy and teracopy.
Running Western Digital diagnostic didnt pick any problems.
Running Windows 7 Home Premium 32bit.
Tried on gigabyte motherboard with intel i3 processor and Asus board with Amd X4 640 processor. Tried with different cables to no effect.
Both drives are sata 2 and have tried on sata 2 ports and sata 3 ports with no difference.

Sounds like there's something wrong with the WD hard drive itself. Shouldn't take that long even if it is a USB 2.0.

Just a single partition?

Do you have "Enable write caching on the device" and "Turn oiff write-cache buffer flushing on the device" set for this drive in the hardware properties?

Sounds to me like for some reason the drive is connecting in PIO mode instead of DMA mode.

This used to be quite common with poor drives for the first SATA chipsets, but it shouldn't be happening these days, especially not on two different modern motherboards.

I'd suggest checking the jumpers on the back of the drive, if it has any. It's possible to force some hard drives into PIO mode using them, although that's becoming less common as well.

Most likely the problem is with the hard drive itself.

sorry forgot to mention. Yes I have set the drive in device manager."Enable write caching on the device" and "Turn oiff write-cache buffer flushing on the device"
First time it took a few seconds and showed enabled then when checked again it wasnt enabled. After resetting again it does show up as enabled each time I check. I am tending to think the drive is faulty despite passing the diagnostic test.

There is lots of diagnostic info available from even the freeware version of

(I have no commercial interest.)

You can never have enough Volvos!

Is it an Advanced Format 4K EARS HDD ? If so, there is a jumper that you need to take of, missing or incorrectly jumoered makes the sectors mis-aligned ....
