I am having trouble getting my Firewire network to recognize my Sony TRV 900. This is a problem that has been intermittent but today it looks very permanent. Here are the basic facts:

1. I have a Maxtor 1 Touch 250 GB, an ADVC-100 and the Sony TRV-900 connected via Firewire to my 1.9 GHz XP Pro machine. The Firewire card is an ADS Pyro.

2. The normal configuration is the Maxtor 250 connected and turned on, the ADVC-100 connected but not turned on and the TRV-900 not connected at bootup.

3. The Maxtor never fails to come up OK under this condition.

4. The ADVC-100 never fails to come up under the normal boot up.

5. Turning on the TRV-900 after the normal boot up fails often and normally hangs the Maxtor 250 GB drive. It becomes inaccessible.

6. Booting with the Maxtor 250 off allows the TRV-900 and the ADVC-100 to come up OK. This is not a cable problem. If I turn on the Maxtor 250 after the TRV-900 connect it is not accessible by the system.

7. Connecting the TRV 900 to the ADS Pyro or the Maxtor 250 does not change the symptoms.

So I seem to have some sort of conflict between the TRV 900 and the Maxtor 250 GB drive. I am stumped on this. I have been solving it in the past by re-booting and crossing my fingers. That has worked until today but today it is failing.

Any inputs would be greatly appreciated.
