USB Firewire devices keep disconnecting

[Carol]

My memory card readers keep disconnecting as soon as I try moving stuff from
them to my PC, now my firewire hard drive, which had worked fine for several
months, also will not stay connected. I have USB 1.1 ports on the mother
board and a USB 2.0 card, a firewire card and firewire ports on my ATI video
card and Creative Labs sound card. It doesn't matter which cards the drives
are connected to, I get the same results with all of them. At first it was
just the card reader in my HP Photosmart printer on a USB 1.1, so I got a
card reader and put it on my 2.0 card. At first it worked ok, then it
started disconnecting. I have a Maxtor 200 GB hard drive on a firewire card.
When I first got the drive it worked great. I even switched it to be my
system document directory drive. Then I optimized the drive and started
having problems reading it, until I couldn't get on the drive at all. I
finally reformatted the drive with XPs NTFX format. The drive is recognized
again, but everytime I try to use it, it disconnects. I have to unplug and
re plug the drive back in for it to show. I start to use the drive and then
I get an error message that the drive is no longer available. I see it's
drive letter is missing and I unplug it, plug it back in and it works again
until the next time I use it.

Does anyone have any ideas why I'm having this annoying problem and what I
might do to resolve the problem?

Thanks,
Carol

10 days ago I swiched from W2K to XP.
After that I had a lot of troubles with my 5 firewire HDD. Like: Disk
get lost, RPC errors, CHKDSK failes. Backup crashed etc. Dozens of
restarts and an overflowing eventlog (System) with many crosses. BTW
some ot the probleme I had before also with W2K.

Then I got the tip that Norton Anivirus 2003 could be the cause of all
this troubles.
I threw Norton out and see - touch wood - the troubles were gone.
I have not a single enty in the eventlog (system) since.
It looks like Norton is not compatible with XP and/or Firewire.
Could it be that it conflicts with RPC?
I replaced it with the German GData Antivirenkit 12

I would like to get reactions.
