Hello,
I've just hooked up my Western Digital MyBook 750G external usb hard
drive to my server in order to make some backups. 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

Every thing *seems* to be working ok, but I really would like to know if
my backups are actually worth while.
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.
