The drive is formated UFS, and it seems to work well. However, when doing large file transfers (ie, using DUMP or gzip'ing files) I keep getting these errors every so often: Mar 10 20:08:34 hive kernel: umass0: BBB reset failed, TIMEOUT Mar 10 20:08:34 hive kernel: (da0:umass-sim0:0:0:0): WRITE(10).

I am running this on a P4-2.5ghz system with 1.5G of ram. I am using an add-in USB 2.0 card (the mb doesn't support 2.0). The main drive is a 120G WD. The onboard controller is also disabled in the BIOS. my dmesg and uname -a: FreeBSD hive.wg.local 7.0-RELEASE FreeBSD 7.0-RELEASE #7: Sun Mar 2 13:46:07 EST 2008 root@hive.wg.local:/usr/obj/usr/src/sys/HIVE i386 Copyright (c) 1992-2008 The FreeBSD Project.
