Firewire problem

[kenmo]

I did not know where else to post this...but I thought someone wanting to use an external firewire case and an burner, reader or hard drive maybe interested in this...

................................................

I purchased a Kobian Mercury 1394 firewire card...
I placed a Maxtor 30gb 5200 rpm I had laying arround. This drive works and the jumper has been removed to identfy this as a single drive....

Using the firewire connection if I copy alot of files, the connection will time out. I get the error write failed... Searching dejanews this seems to be a problem with firewire and Windows 2000....

If I use my USB 1.0 connection on my computer (MSI 6330 & AMD 1800), every thing works BUT it's slow....

If I connect the USB to my 2nd pc (WinXP, MSI 6590 & AMD 2500) it also works and it's fast...

I purchased this enclosure to use on my Windows 2000 as it is my video editing pc...However my ATi TV wonder card has issues with Windows XP and behaves strangly ...

So I moved the firewire card and encloure to my WinXp pc and it worked flawlessly... I copied several DVD Video folders to the external firewire and all went well....

Further searching on Dejanews led me to this info at the Maxtor site

Here is the solution :

"Changing PCI latency to 128 seems to fix the problem. However, it is suggested that you change the 1394 packet size from 2 Kb to 1 Kb by downloading and running 1tchcfg.exe utility."

I have not actually tried this solution as my Win2000 was busy encoding a few avis to mpegs....

Has anyone else had this problem ????

Sure haven't I switched the Firewire about the time I switched to XP so I didn't really have time to run into anything like that.

Good stuff. In my case I fixed the same problem by upgrading the firmware of my fire wire case. Since it uses Oxford 911 chipset I was able to download a newer firmware and tweak some ATA parameters. After these changes everything was great.
