Perhaps the slice size is wrong. Is it safe to install the FreeBSD without using bad144 to scan the drive? What I mean is: does FreeBSD 2.2.5 uses ATA's bios capability of mapping bad blocks? And I didn't understand how can the slice size could be wrong since I'm not using fdisk directly to make them but the install program itself. > > >1.
