Did you read/review the Simpletech manual or get it from its support website? That way, you know more about it, etc.. Next, just what are your Sony USB ports, etc., are they actually USB 2.0. If there any possible s/w provided by Simpletech to help resolve this? Are there any red/yellow flags at "device mgr." area for USB device or that device?
I have a Simpletch 320GB exterhal HD. It's a USB 2.0 Drive. I have it plugged into a Sony laptop that only has 2.0 ports. There are NO drivers issued by Simpletech as they consider this 'plug and play'.
However, I cannot get this device to transfer at 2.0 speeds. When I plug it in, I get the 'This device can perform faster' alert. But I've never been able to resolve this.
The HD is formatted NTFS, and no other external drive has given me issues. Furthermore, I've used other cables, and THEY haven't helped.
I don't think this is a hardware problem because the HD works fine - just really slow. It's a couple years old and past its warranty, so I'm hoping someone can help me with this issue. If I can't get it up to 2.0 speed, I'll have to ditch the drive and find a manufacturer that can.
