file transfer speed...very slow

Whe transfering 4 files from a thumb drive to my vista system...or visa
versa...taks a very long time...much longer that on my xp system. I
addition I am asked to varify my actions each time...whic slows things down
even more.

What can I do?

I found that turning off "Remote Differential Compression" sped up my file
transfers significantly. You could try it by:

Control Panel|Programs and Features|Turn Windows Features on or off|uncheck
Remote Differential Compression.

I have found no negatives to turning off RDC, and you can always turn it
back on again.

I also understand SP1 will be addressing this issue as well.

Hi, AJB.

Your USB thumb drive is 2.0, right? And all drivers, hubs, and other
components are 2.0? Since you are running Vista on this computer, I assume
that your USB is all 2.0, but if you are using legacy hardware or software,
it might be using the older, slower USB.

Hi,

Actually that brings to mind a good question (I think).

My computer was built with 14 months ago and I would assume all USB ports
would be 2.0....

How can I check this is true for all the computers' USB ports (Front and
back, etc.)?

Possibly this has been suggested, but...I found that my file transfers both
to external devices and within my hard drive were greately speeded up when I
disabled Remote Differential Compression. You could try it by:
Control Panel|Programs and Features|Turn Windows Features on or off|uncheck
Remote Differential Compression.

I have found no negatives to turning off RDC, and you can always turn it
back on again.

My thumb drive is 2.0...wow and I check on my desktop usb?

How much of a difference should I expect to see...I hae follwed your
suggestion and am looking to see change.

The only quantitative test I did was a quickie test, consisting of copying a
1.91 GB
folder from my main hard drive to a folder on an external USB drive.

Results:

With RDC turned on: 3:23 - three minutes and 23 seconds (using a
stopwatch).

With RDC turned off: 2:25 – two minutes and 25 seconds.

So this quickie test reduced the copy time by about one minute, or a 33%
improvement. Not sure it is a valid test, but interesting. I also am
observing much faster file copy and move within my hard drive, remarkably
so. The whole system feels faster. Note that I did not do a reboot after
turning RDC off. I will leave it off, because even though my file
transfers were quite fast before, they are even faster now.

Will be interested to see your results.

Hi, AJB.

The fastest drive in the world will be slow if it is plugged into a USB 1
port. That's why I asked about drivers, hubs, etc. And you didn't answer
that part of the question.

If you have a brand new motherboard with all USB 2.0 ports, but with an old
legacy USB 1 hub plugged into your USB 2.0 motherboard port, with the new,
fast, USB 2.0 drive plugged into the hub - you'll get only USB 1.0 speed.
:>( Simply plugging that drive directly into the mobo, bypassing the hub,
might solve your problem.

The old "weakest link" analogy comes to mind.

I could make other guesses, but I would just be shooting in the dark without
knowing more about your whole USB "chain".
