7500 G4/800 Firewire problem |

Using MacAlly USB2.0/Firewire combo card and Radeon 7000, running 10.1.5. USB works fine, but the minute I plug in something firewire, it freezes. I've even tested it with NO USB devices present. The machine will not finish booting if a FireWire device is present. I have made it to the desktop, but it froze after appearing. I managed to see this next bit via the Radeon/verbose mode anomaly when I booted into 10.1.15 and then connected the FW: Creating new device 0x0x36f0500 Found old device 0x0x36f0500 IOFireWireDevice, ROM unchanged IOFireWireDevice, ROM gen zero This repeats twice and then everything freezes solid. Unplugging the Firewire device does nothing to unfreeze. The MacAlly card seems to work fine in 9.2.2, although it seems to hang during large read/write, but I just let it sit and everything turned out fine. It even burned the audio-CD correctly. Anyone have any ideas for how to solve this? Perhaps the PCI 2.1 spec is too much for my 7500? Do the Ratoc or Orange cards have 2.1 reqs? |

For what its worth. Many of us are using external drives utilizing the Oxford 911 bridge. My external case is from ADS. I got dismal performance from an Orange Micro Firewire/USB 1.1 card which using the Optiplex chip for firewire. This is what ADS has to say: Q2) Is the PYRO 1394 Drive kit compatible with all 1394 Host controllers?? Â A) The greatest majority of 1394 host controllers in the market are from the following companies: * Lucent OHCI Compliant IEEE 1394 Host Controller * Texas Instruments OHCI Compliant IEEE 1394 Host Controller * Agere OHCI Compliant IEEE 1394 Host Controller PYRO Drive Kit works very well with these devices. However, we have experienced issues with drives not mounting or connecting properly with 1394 host controllers with the following manufacturer`s chipsets: * VIA OHCI Compliant IEEE 1394 Host Controllers * NEC OHCI Compliant IEEE 1394 Host Controllers The PYRO Drive Kit is built with a Texas Instruments chipset. We have seen issues where VIA and NEC host controller cards do not communicate properly with Texas Instruments chips. Therefore, we recommend using 1394 Host controllers based on Texas Instruments or Lucent or Agere. Currently have now used a Tempo Trio which uses the Agere chip and now an Adaptec FireConnect 4300 which used the TI chipset. These work great. Finally normal speed when copying files and flawless playing of DVD's. It seems that the chipset is very important when using Firewire cards in any version of OS X. |

I tried a Rapidfire USB/FW combo card and an Iogear USB2/FW combo card in my 9600 with no luck. Constant FW freezes & corruption. I ended up with an OWC 3-port FW card and an Iogear 2-port USB2 card and FW performance is both stable & quick. There was no reformat required and I used Apple drive set-up originally. The dedicated FW card instantly cured all problems I was having with the combo cards. It utilizes a Lucent chipset which may be important for the older machines. The only problem is that the Iogear USB2 card is not recognized in OS9 but I don't depend on 9 much anymore. I intend to get another USB card that functions in both systems for the 9600 and put the Iogear in my G4. |

Hi gkphoto584, I have a question, how is it possible to formatt a firewire drive with HDST? On my 8500 with G4/400 and USB/FireWire Combocard HDST 3.5 does not see my firewire drive. It is working, but not very fast reading, only 3.500 MB/s, writing with 14.000 MB/s. |

P.S. The new card is USB 2.0 / Firewire. |

After my G4 800 upgrade on 7500, I had to retire my firewiredirect.com card, for a new card. The new card is generic from an ebay merchant, and is with NEC(USB) and VIA (firewire) chipsets. I also had to turn in my owc external firewire drive (Pre Oxford 911) under warranty, and get a new one with Oxford 911. The old one would hang the system during file copies. I recently noticed a boot problem if I have my Sony TRV-10 digicam plugged in. I noticed that apple doesn't list that as a supported digicam. I can plug it in after bootup, and it works fine under OS 9, but occasionally hangs during large transfers under OS X. The error message complains that the hard drive isn't responding fast enough, but I doubt that that is the real problem, because I am writing to an LVD SCSI drive on the ATTO controller. |

I had all sorts of firewire problems with my G4/800mhz PowerCentre and PowerWave machines, but they all went away after I formatted my firewire drive with Hard Disk Speed tools. |

I have a Ratoc Firewire/USB2.0 card that works perfectly in my Power Tower Pro w/Sonnet G4 800. The only anomaly that I've found is that it does not like the 5th PCI slot at all. Copying and writing to a FW drive hangs if the card is in that slot. I don't remember for sure but I believe it is PCI 2.1 compliant. I'd have to dig up the box to be sure. |
