Ok, I have narrowed down my problem a great deal. It appears that FreeBSD cannot read the partition table of my 300 GB Seagate Barracuda. My dos diagnostic utility works because it accesses the disk in a different way. I used the entire disk (one slice/partition) and attempted to format it. This is what I get after it reaches the end of the disk: "cg 0: bad magic number" It also slows down significantly about 3/4 through the procedure. Now the funny part. I create two partitions and the newfs output is exactly the same as before when I try to format the first partition! It tries to format as if there is only one partition and produces the same error. If I remove the slice via sysinstall and then try fdisk I get this: # fdisk -vBI ad3 ******* Working on device /dev/ad3 ******* parameters extracted from in-core disklabel are: cylinders=581421 heads=16 sectors/track=63 (1008 blks/cyl) Figures below won't work with BIOS for partitions not in cyl 1 parameters to be used for BIOS calculations are: cylinders=581421 heads=16 sectors/track=63 (1008 blks/cyl) Information from DOS bootblock is: 1: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 586072305 (286168 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 1; end: cyl 812/ head 15/ sector 63 2: <UNUSED> 3: <UNUSED> 4: <UNUSED> fdisk: Geom not found Anyone? -- Peter __________________________________________________ Do You Yahoo!?
