Isnt that one of those Western Digital Green drives ? I seem to
recall a number of people complaining about similar issues where the
drive stalls. Perhaps a firmware update ? Or perhaps a way to disable
the power saving/spin down features ? Is your controller set to
AHCI, or regular SATA. what does /var/run/dmesg.boot show ?
