Please help!

The problem persists. Built new world and kernel. The system is now 7.1-STABLE amd64.

When booting up, the system gives messages

da0 at twa0 bus 0 target 0 lun 0
da0: <AMCC 9650SE-8LP DISK 4.06> Fixed Direct Access SCSI-5 device
da0: 100.000MB/s transfers
da0: 1430481MB (2929625088 512 byte sectors: 255H 63S/T 182360C)
GEOM: da0: corrupt or invalid GPT detected.
GEOM: da0: GPT rejected -- may not be recoverable.

also

# dmesg |grep da1
da1 at twa0 bus 0 target 1 lun 0
da1: <AMCC 9650SE-8LP DISK 4.06> Fixed Direct Access SCSI-5 device
da1: 100.000MB/s transfers
da1: 1430481MB (2929625088 512 byte sectors: 255H 63S/T 182360C)
GEOM: da1: corrupt or invalid GPT detected.
GEOM: da1: GPT rejected -- may not be recoverable.

The question is why does sysinstall say?

"WARNING:  A geometry of 182360/255/63 for da1 is incorrect.  Using  a more likely geometry.  If this geometry is incorrect or you  are unsure as to whether or not it's correct, please consult  the Hardware Guide in the Documentation submenu or use the   (G)eometry command to change it now."

182360/255/63 is exactly the number what driver gives at boot time. Still 
182360 * 63 * 255 = 2929613400

2929613400 does not match with 2929625088   ( -11688 sectors)

How can I fix this?


With best regards,
O.K.
