After updating my macpro to 10.4.11 it does not reconise any external harddrive.
After a update for 10.4 and now 10.4.11 it does not reconise any external harddrives. I had tried 3 different HDD and format tipes.

Hello,
Do they show up in Disk Utility at all?
Not in finder or in disk utility. Restarted it about 10 times
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime.
Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
reset-nvram
set-defaults
reset-all
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

Try taking the battery out for 10 minutes. Put battery back in. Cross fingers. Power the machine back on.
