>Description:
When attempting to access an Apple Powerbook when it is placed into target mode, I am unable to access the drive, but it is detected as an SBP-2 device.

I cannot read the drive in any way, tried diskinfo, fdisk and dd.


Output when sbp is compiled with debugging on:

Connect a Powerbook in target mode to a FreeBSD machine.

Run camcontrol rescan all

Attempt to fdisk the new disk
