My daughter's iMac presents the infamous flashing folder and alternating question mark. It starts from my DiskWarrior 3 startup disk, but DiskWarrior does not recognize the drive (doesn't even show it in the drop down menu.)
I tried to boot the computer in Firewire mode and repair from my PB17, but when holding the "T" key and starting the iMac, it simply restarts.
Any suggestions? Bad HD?
