Fixing Firewire in SP2

[Treeman]

I had no idea why my firewire bus got dorked by updating to SP2, and MS couldn't figure it out either. (external Maxtor HD, DV Camcorder not working, computer hangs on shut-down)

I did find the fix at this web site: Firewire

I followed the instructions and now I can write, read, format, and defrag this external drive. It involved setting back the system drivers for ohci1394 to Sp-1 drivers.

The only fly in my soup now is in Computer Management, Disk Manager. It says the external drive is, "unreadable, this device is working properly."

I hope the link provided helps out folks with firewire, to get it back to a normal state.

Maybe someone could shed some light on the disk management problem!

Thanks,

Firewire support in SP2 is not great... I'd use the unibrain drivers if possible. Check it out at http://www.unibrain.com, it's good stuff.

that's really dumb of MS ?? why the heck did they do such a thing? security?? wierd..

I had problems with sp1 firewire so I end up using usb 2 (hopefully my external hdd and dvdwriter has multi interface..)

if I was compressing a video (read/write to same hdd) and then try to do another job (say open a program from that hdd)

windows would claim that it couldn't write and failed to write or something similar to that, and since i'm not patient enough to be doing 1 job at a time i went back to usb 2...

unibrain's site tells all about the issue in depth... It's fairly long so I won't copy/paste it. I use mostly USB2 (for CF card readers, external HD, etc) and firewire only when I shoot docked with my DSLR (not too often). I suppose I've been mostly lucky, I've never had problems with it yet.

/me knocks on wood

Yup, I don't get how it was a "security," update. I do know it kills 1394a (400mbs) and the new 1394b (800mbs.) I'm slowly fixing this mess on 3 computers, all have firewire.

The Computer Management Console > Disk Management, ala new SP2 drivers, (signed) is still showing my external drive as "unreadable."

I wonder if it's a group policy that's protecting me from the dangers of an external "networked," drive? Just a thought.

Jump in anytime.
