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. Remember: you need to enter whatever your BIOS thinks the geometry is! For IDE, it's what you were told in the BIOS setup. For SCSI, it's the translation mode your controller is using. Do NOT use a ``physical geometry''. then i'm back at the main fdisk screen and it says at the top DISK Geometry: 4111 cyls/255 heads/63 sectors = 66043215 sectors (32247MB) dmesg identifies the drive thus: ad2: 32253MB [65531/16/63] at ata1-master UDMA33 i readily admit to not fully understanding the intricacies of disk geometry and what the BIOS thinks. i was under the impression that freebsd doesn't use the BIOS once it has booted. this isn't a boot disk, it's for data only. any ideas on how i can fix this? -jsd- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
