I have a new 4TB external drive. If the device is on, my mac will fail to boot (blank white screen) and when the drive is turned off, reboot immediately resumes. I cannot boot to safe mode, single user or verbose when the drive is on.
After boot and I turn on the drive, disk utility does not recognize the drive, but system profiler does see the HDD as an unknown device. After about 20 minutes Disk utility finally sees the drive
/dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: *4.0 TB disk2
Disk Utility (GUI) does not allow me to verify, repair or partition the disk and it appears as unformatted and read only.
OSX 10.6.6 - Drive IOMEGA UltraMAX Plus 4TB (2 bay stripe set) - Connected via firewire
If I cannot erase or partition the drive, what is my next step?
