I unplugged my firewire drive by accident and now non of mine external firewire drives will mount. Tried different cables; firewire 400, 800 and USB, nothing. Diskwarrior and Disk Utility don't see the drives.

Powerbook 1.5Ghz, 10.4.11

I tried the search with no results.

Thanks

Did you try the drives on another computer to see if they work? Did you reboot? If any of the drives are bootable, did you try holding down the option key at boot to see if they're seen as boot drives?

Hopefully you didn't fry your ports.

Does the System Profiler see the Firewire port at all?

What *can* happen is that a quick disconnection and hasty reconnection can fry your Firewire controller.

If you restart in verbose mode (hold down "v" when restarting), one of the lines near the beginning of the boot sequence will read "broken Firewire phy" if that is the case.

Frying the Firewire ports is pretty common on PowerBooks.

Nothing will mount anymore: four different hard drives, iPod (is still charged) and a firewire CF card reader.

When I went in verbose mode it reads: Firewire: build in non active. I had a Lacie drive connected with firewire 800 and iPod with firewire 400 at start up.

In the System profiler it says:
Hardware: firewire maximum speed up to 800MB/sec
Network: No information found

Any clues, tnx

When I use the USB2 ports the drives mount fine, besides that I can still access the drives, I guess this is not looking good. I specially use the 800 drives as scratch disks for final cut and PS.

Try resetting the PRAM on restart.

Also, try resetting the nvram in Open Firmware.

Still not working...the firewire drives don't work either if I have them connected on another drive that's connected with USB2 to the powerbook.

That has NEVER worked (and CANNOT work, as Firewire and USB are completely different protocols that are handled by entirely separate controllers within the drive enclosures).

Based on experience of my own, and related to other comments in these responses, it sounds like the connections between your external HD and your computer are damaged and need replacing. The way I was able do it, was purchasing a a new case for my external HD, plugging the actual HD into the new connections, and then discovering that now my external HD is there, and usable. I hope the same for you. Good luck!

But unfortunately it's with all my external drives (two Lacies and a Wiebetech), iPod and the CF card reader. I can still use the Lacie drives with USB2.
