WD MyBook VERY slow in Vista..
Hi all..

Just upgraded my PC to Vista..

My WD MyBook Premium 320Gb seems very slow to copy files now..

I basically get a transfer rate of 11 MB/s (USB2)

I'm sure it was much faster on my old XP machine...

firstly, should I be getting faster transfer than this?
Is it slow because it's FAT32 on the MyBook and the PC is NTFS ?
can I convert the MyBook to NTFS without losing all the data on it?


Thanks in advance all...

I remember only scant details about this issue; but, I think it was Western Digital who limited file sharing from the MyBook and consequently file transfer rates were severely restricted. Somehow, this "feature" of the MyBook gets triggered in Vista even when not being used on a network.

This was WD cow-towing to the RIAA, I believe.

Like I said above, I may be wrong about some of this; but, it might be worth looking into.

Mine isn't the NAS version... it's just a plain old hard-drive...

..connected via USB2.. no networky stuff involved.

I've upgraded to SP1 for VIsta.. and now get speeds of ~18MB/s generally...

Is this as good as it should get?

(also, I got a bit wrong - the drive is connected via Firewire)

That's within the range that I get. I take it this is just copying from the internal HD to the External. I think Vista is still slower even with SP1 (no doubt about its being much slower without SP1). I haven't tested with my Firewire drive but my USB drives can vary quite a bit depending on if I'm pushing a file over the network, or pulling a file from a network place, wether the place I'm pulling from or pushing to is NAS (always seems to cut the speed in half) or not and what the USB bus share status is of a particular drive.

That's said, I get anywhere from 4MB/s (push to 10/100 NAS) to 28 or 29MB/s (pulling from same system single use bus USB drive).

Do you get different speeds reading from vs. writing to? 18MB/s is decent but I think you should be able to get almost twice that speed in an optimum situation. I'll do some testing with my Firewire drive on Vista and see how I fare and get back.

Results with LaCie firewire drive using TeraCopy to measure speed of transfer, local from internal to external and back several times using one .75 gig file:

XP Machine #1 Write speed = 28.5 MB/s Read speed = 36.5 MB/s
XP Machine #2 Write speed = 33 MB/s Read speed = 33 MB/s
Vista SP1 Machine Write speed = 07 MB/s Read speed = 33 MB/s

Conclusion based on tests: For whatever reason Vista sucks yet again.

wow.. thanks for running those tests.

I haven't managed to get up to ~30MB/s read... did get to ~20MB/s though..
and write was a bit faster at ~11MB/s.

seems there's nothing particularly wrong with what's going on.. just Vista crapness.... and as you say, the numbers seem "within range".

It took 35mins to copy 37Gb last night.. which I can put up with, as I only have to do that sort of backup once every few weeks or so.. so it taking half an hour (rather than the quoted 1h46m when I was pre-SP1) is reasonable.

thanks again....

So.... Vista is an "upgrade"?

MS should give every vista own a copy of Windows7 for free, for dealing with the crappyness of vista.
