I'm using the newest firewire driver (http://people.freebsd.org/~simokawa/firewire-20020918.tar.gz) To test a 160GB IDE drive (in a box), through the CAM and passthrough drivers I have no problem locating the device (da0) but the geometry of the drive found makes me believe that there is a 28bit addressing mode bottleneck somewhere as the log reports that 268435455 512 byte sectors found. (~131GB) (I believe 268435456 being the 28bit limit?) Although using it is OK I'm still wondering if it would be possible to locate the missing 20GB before the disk actually goes into active use. I'd like to know what is causing this limitation? From the hardware I have: FreeBSD 4.4 -> make buildworld to 4.6.2, latest kernel: 4.7-RC FreeBSD 4.7-RC #0: Sun Sep 22 01:39:47 EET 2002 Firewire PCI card: fwohci0: and a Western Digital 160GB drive in a standard firewire box. Again, accept my apologies if this is the wrong place to request help\clarification on the matter but any help or hint is appreciated.
