Hello I finally got another hdd for my home box, decided to do a fresh fbsd install and I ended up with a disk problem :( : ide0: 40GB [FreeBSD wannabe (ufs2) 10GB, storage2 (fat32) 30GB] ide2: 40GB [WinXP (ntfs) 10GB, storage1 (fat32) 30GB] Now when I begin the installation, and go to the partitioning section, fdisk complains about drive geometry and rearranges the drive. Here are the settings: cyls/heads/sectors 19xxx/16/255 (BIOS) 7xxx/16/63 (dmesg "this is what fbsd complains to") 4xxx/255/63 (the new fdisk rearrangement) and FreeBSD's fdisk seems to get off on setting the head count to 255!!! I tried setting the bios value and fdisk complains again, but for some reason when I swap the heads and sectors values it does not. Same goes for the dmesg values (drive geometry from the dmesg output). Since I have no experience with changing drive geometry, nor do I understand the bloody thing, I have several issues: - Will I loose the data on 'storage2' if I change the drive geometry? - How should I set up the new drive geometry? What setting is faster/better? more cyls or more sectors (since fdisk is set to use 255 heads)? - If I backup 'storage2', change drive geometry as fbsd/fdisk suggests (or whatever), create a 10g slice and leave the other space unpartitioned, will I be able to partition and format the drive to fat32 from WinXP? That's about it... any examples would be great! thanks ahead!
