I installed a new 10GB disk last week, and suffered the following problems. I mounted it in a Pentium 120 as the second drive, and created a 4 GB slice for FreeBSD, and a 2GB slice for Win95, leaving the rest unused. I installed FreeBSD (3.1), and it ran fine. Then I used Win95 to format the DOS partition, and that seemed to work too. When I rebooted FreeBSD, it ran for a few moments (getting all the way into the KDE toolkit), and then spontaneously rebooted. On rebooting again, the /usr filesystem was damaged beyond repair - fsck threw up its hands in disgust. I have now devoted the entire disk to FreeBSD, and it seems to run fine. Am I living in a fool's paradise, or can I reasonably expect it to run OK if I don't let Win95 anywhere near the 10GB disk? BIOS is an Award Modular 4.51PG, Rev 1.04.
