The official specs from Seagate say it reports a default logical geometry of 16383/16/63, but that only covers 8G... There is no other mention of geometry in the specs; it simply says that using LBA the sectors are addressed 0...n-1 >>If I go ahead and attempt to partition, I see >>Geometry ad4 9729 cylinders/255 heads/63 sectors = 156296385 sectors >> (76316MB) >> Offset Size(St) End Name PType Desc SubType Flags >> 0 63 62 -- 12 unused 0 >> 63 16386237 16386299 ad4s1 4 NTFS/HPFS/QNX 7 >>16386300 139915188 156301487 -- 12 unused 0 >> > > > This one is fine.

The only problem is that the geometry was reported as bad by sysinstall, and implied I needed to change it. Yet the partition step appears to have changed it already, or is assuming it will be changed. I don't understand what the situation is: sysinstall reported geometry as 155061/16/63 and said it was bad then partitioning assumes it will be 9729/255/63 Do I actually have to run pfdisk to change it from 155061/16/63 to 9729/255/63? One more question: The installation notes say the root partition must be below cylinder 1024. If I want a largish (8G) partition for windows, how do I accomplish this? Do I have to make 4 partitions, a small one for booting windows, a small one for freebsd's root, and then a larger one for the rest of windows and another larger one for the rest of freebsd? e.g. cyl partition use 1- 511 1 windows boot 512-1023 2 freebsd / 1024-1500 3 windows additional stuff 1501-9729 4 freebsd filesystems other than / Thanks, Gary
