Vista Hp X64 / Vista Users Transfer Rate Issue

Recommended Posts

Big hello to any DIY-Street members/mods and OCC mods/members.


As mentioned in another thread I have been using Vista HP x64 for 6 months (testing) and have run into a problem which I need people to test.

See sig for details on setup.


80GB drive with just Vista installed (SP1)

80GB drive with important data (30GB)

External USB drive


The problem,

I wanted to tansfer my important data to the USB drive, this data consists of uni work (docs,xls,ppt), pictures (jpg,bmp.gif), game patches, drivers, mp3 files, acronis images of my hard drive + other hard drives, loads of other stuff which I need/emails. So its quite a random bunch and equals 30GB.


Started transferring this to the USB drive in Vista and it started out at a very high transfer rate which settled down to 40MB/s and gradually kept failling until it reached 1MB/s. At this point Vista reported more than 1.30 hours to complete the transfer.


I had a feeling that something must be wrong so decided to try copying from internal drive to internal drive, the same thing happened.

Obviously I had no choice and waited the 1.30 hours for this to complete.


Now I am not quite sure where the problem lies, it is either Vista or a drive setting that I have done with the Vista setup that has caused the issue, the same thing happens in Vista safe mode. (plus superfetch and readyboot disabled)


To test I have wiped out the hard drive and put XP home and it did the same 30GB transfer in 13mins (internal to internal)

So I am 100% certain that it is not a hardware issue.


What would be good is if people with Vista can try to transfer a bunch of random large files at least 20GB to another drive to see what happens.

I am aware that this is an issue that MS claimed to have fixed in SP1.


- I had Vista with my drives running in AHCI mode.

- XP drives have been tested in IDE and RAID mode <not configured so each drive is acting independently.

Will try AHCI mode next under XP to see.

And RAID <not configured under Vista.


Thanks for any help.


EDIT: Problem solved, Reinstalled Vista and everything was back to normal.

My only explanation is that I must have done something with the drivers/settings which caused the issue.


But XP transfer rates are still that bit faster especially when using the USB drive. (3 mins faster)

That's an odd problem to have. I've never messed with mine but transfers have never slowed down like that. I assume you have/had SP1 installed?
