New install of Vista Ultimate x64. Drive C is a new drive which works well. Drive D is an older SATA 3.0 drive - both WD. When copying from drive D to drive C with large files the transfer starts out well enough at 55Mb/sec and slows down once around 2.5 GB are transferred. It slows down almost at once to a stop, and then continues at 100kb/sec. What in the world is causing the change? ICH9R is the chip on the motherboard (ASUS P5K Pro). I had the SATA set for IDE at first, then updated to ACHI using Microsoft's regedit update to enable ACHI after Vista was installed. This slowdown happens in both cases. Drive C to an external HD via firewire does not exibit this slowdown, but drive D to the same external HD does. Any ideas for me to look at and try? -- Skyham |

Have you upgraded to SP1? There are changes introduced into SP1 that address situations like this.

One of the first things I did was to install Vista64 and load SP1 prior to connecting this second drive. I think it may be a drive fault. I pulled this drive from another machine, and I had to jumper it to run at 1.5 MB/s (SATA1) in order for it to work in the old box, and I had thought it was a motherboard issue there. If I try to re-jumper the drive to SATA2 3 MB/s Vista sees it, but not as an available drive. In the diskmngr it appears, but won't initialize it complaining of an unspecified error. If I jumper it to turn spread spectrum on it doesn't work, only as it was originally set at the slower rate. I have another drive on order which should be delivered tomorrow and my question will be answered one way or another. Thanks for your thoughts. -- Skyham |
