I'm running 2.2.5 stable with an adaptec 2940 UW and a seagate
ST39173W, which is not for booting.
The disk has 7520 cyls and 10 heads, according to the manual.
dmesg says it has 17783240 sectors.
Fdisk says:
"A geometry of 7503/10/237 for sd2 is incorrect. Using a more likely geometry"
It uses 1106cyl/255trk/63sec which gives 17767890 sectors. Close enough.
I assigned the whole disk to fbsd.
When I attempted to run disklabel from /stand/sysinstall, it bombed
with no error messages I could catch.
So I ran "disklabel -r /dev/rsd2 >proto" and edited the file.
----------

I just added the A partition and fixed the rpm.
It updated the label fine, but when when I do a newfs, I get
Warning: 622 sector(s) in last cylinder unallocated
/dev/rsd2a: 17767826 sectors in 4338 cylinders of 1 tracks, 4096 sectors
8675.7MB in 272 cyl groups (16 c/g, 32.00MB/g, 7680 i/g)
Newfs thinks it has 1 track/cyl. Is there any rhyme or reason to the above?
Should I just ignore the geometry numbers and let it think what it wants?
Will I run into problems down the road?
It would be nice if newfs agreed with disklabel ...
By the way, what do the asterisks mean in the partition cyl lines?
I assumed it meant the partition boundary is not on a cyl boundary...
Thanks for any advice!
