I've tried the hard drive connected via eSATA as well as directly into the SATA bus and no joy - same error on both buses. When used under NetBSD 5.1 or Windows 7, no such error message is seen. FreeBSD is able to update the MBR (I've done so with fdisk) and read data from the start of the partition without any trouble. There are others in the FreeBSD forums encountering this issue with hard drives made by different manufacturers on different systems. Mine is a Hitachi drive in a Dell. >How-To-Repeat: Boot FreeBSD 8 with a current model 2TB HDD connected to a SATA/eSATA bus. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
