| firewire wont read peripherals i have a mac mini which up until recently was working fine. now it won't read my external lacie drive, my lacie d2 burner or my m-audio firewire solo. i've tried rebooting, unplugging, replugging, switching cables...all to no avail. i hate to think that i have several hundred dollars worth of paperweights now. the system profiler recognizes that i have a firewire port, only when i plug something in it doesn't read it. are the ports on my peripherals fried?  |

| Unplug the drive and reset your Pram.

| i did that and i ran tech tool pro which says the firewire port is fine. could it be the firewire cables? i can't believe that every single one i have is bad or that every port on my peripherals are fried. |

| Did you upgrade to Leopard? That's what screwed my Firewire on my iMac G5. I strongly suspect one of the firmware upgrades along the upgrade path to 10.5.2. What's even worse is that I can't downgrade to Tiger, boot up off my old Tiger DVDs nor get it to boot into Diagnosis mode. I have done a complete clean install and an archive and install, zapped the PRAM, booted into safe mode etc. Nothing works. |

| it was working even with 10.5.2 but now when a particular firewire cable is plugged in it says unable to locate firewire or something similar on the about this mac window. otherwise it just says firewire 400/mbps. i'm taking it to the genius bar today at the mac store to see what the problem is. |

| If it is just a particular FW cable it is probably the cable or the plugs on the cable. It is possible for the connections inside the plug to get bent and misaligned, it happened on one of my cables. I've also had one out of 2 ports on the back of one of my drives become unreliable. |
