Speeding up Firewire File Transfers?

Milo_Mindbender asks: "I've got a pretty common problem: copying a ton of files from an old Windows XP computer to a new one. After noticing how long transfers were taking over my 100mbps Ethernet, I hooked up a IEEE1394/Firewire cable and things were much faster. Strangely though, Windows is still only using about 10% of the cable's 400mbps bandwidth. Does anyone know any tips/tricks for speeding this up or any Shareware mass-file-copy tools that would be faster than Explorer/file sharing? Right now, the older machine is setup with Windows file sharing and the new machine is copying from it, neither machine is using much CPU and the disks are nowhere near their max speed. The number and size of the files might be what's slowing it down, since it's gigabytes of files in the 100-200k size range."

archive then move?

Have you tried to archive/compress them first [gzip/zip/etc], then move the big file over? Lots of small files take longer to move than fewer larger files. /vjl/

Move the old hard drive, then copy

[TheArtfulTodger]

Why not just plug the old hard drive on the secondary channel on the new PC, reboot and then just file copy? Or do I need to reread the question?

The problem with doing that is Windows can detect the "magic" folders... Mods: If you don't know what "magic" is, please mod some other comment. Thank you.

Do you mean the software named "Magic Folders"? Or perhaps you have some kind of Folder of Holding with compression created by a high-level Magic User. Most likely you mean the Special Folders that are used by Windows, but then again you may just be spouting about something you actually know little about.

Or maybe you should just explain yourself and not flame the mods... You might even get modded +Insightful or +Informative then and you would have the advantage of explaining your term to the person you were answering - thus being genuinely helpful.

BTW, I learned the term "magic" from the Microsoft tool "tweakgui". I didn't invent it.

I looked in TweakUI and it calls them "Special Folders" as well. My point is: Be careful about how you present things that you may only have cursory knowledge of here on Slashdot. I was being funny about it, but there are planty of users out there who will ream you for bad information. Instead of being authorative and telling the mods what to do, you could have replied in the form of a question such as "You could try, but won't windows have problems with the magic folders?" or something like that. Further, you could disclaim being an authority and just post something along the lines of "I think that...".

Ok, I'm done being a slashdot post nazi now :D

From my experience, XP stores the hard locations (ie: c:\Documents and Settings\BrynM\My Documents") for the special folders it needs in the registry. I've never had a problem slapping a previously used drive into a machine to copy files (I did this exact thing to recover files after and IDE failure that was corrupting NTFS just a couple of weeks ago). If you've had problems or know of them, then please post that.

Here you go.

Firewire is crippled in Windows by default. You need the patch here to restore functionality.

Firewire 400 is 400 megabits per second.

A modern SATA drive can do just shy of 70 megabytes per second, which is 560 megabits.

Pay attention to units

Strangely though, Windows is still only using about 10% of the cable's 400mbps bandwidth.

Are you sure you aren't confusing mbps with MBps? 400mbps is equal to 50 megabytes per second, and "12.5% of the cable's bandwidth" sounds suspiciously like your description of the problem, "about 10% of the cable's bandwidth".

Re:xcopy?

[1u3hr]

Is there now a version that supports long filenames?

See my earlier post about XXcopy, http://www.xxcopy.com./

Have you tried this?

There is a problem in Windows XP SP2 with firewire transfer. Albeit that it could be numberous small files creating problems but it should be faster than 100mbps ethernet. Try this blog regarding Windows XP SP2 Firewire Slowness for a link to the KB and a links to few other work arounds or just go direct to the KB article.

"Modern? This is from an old computer to a new computer - and those speeds would be for consecutive data. Which I suppose is fair, given that the user defragmented completely. But an IDE drive's speed is far less 400mbit/s."

They're just about as fast as SATA drives, since ATA-100 is still faster than the sustained speeds of the drives (100 is megabytes in this case). This is why ATA-133 never caught on -- it's faster than any of the drives you'd connect it to. It wasn't SATA's speed that made it popular, it's the numerous other advantages (thinner cable, cheaper, hotplug, etc).
