Please help!

The problem persists. Built new world and kernel. The system is now 7.1-STA=
BLE 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 w=
hether or not it's correct, please consult  the Hardware Guide in the Docum=
entation 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=20
182360 * 63 * 255 =3D 2929613400

2929613400 does not match with 2929625088   ( -11688 sectors)

How can I fix this?


With best regards,
O.K.
