help installing FreeBSD

[adrian esquivel]

Hi! I've been trying to install FBSD on my computer, but I keep getting an
error message that I have absolutely no idea what it means. This is what I
get when I hit Alt+F2

I've got a Maxtor of 60GB as primary master. My geometry is wrongly reported
by the installation program, it reports a geometry of 119108/16/63 while the
BIOS reports one of
1024/240/63. I think this has nothing to do since I'm planning to have
FreeBSD as the only OS of the machine, but you never know...
These errors are shown just after I leave the partition editor, when they
give the warning of making Back ups. Then the 'Writing partitions; message
is shown and then the last one that says: "Unable to make new root
filesystem on /dev/ad0s1a! Command returned status 36"
Please help me! I've been asking everywhere and nobody answers me... Is
there no solution for my problem????
