[Voyage-linux] MPD corrupting files?

[Joshua Anhalt]

How are you powering the new hard drive?

Is the hard drive spontaneously disconnecting/reconnecting?  Look in the output from "dmesg", or in your /var/log/syslog.  If so, check your USB cables and make sure there is sufficient power for the drive.

Are there any warning signs in the output of "smartctl"?  (smartctl cannot access all types of USB connected hard drives, some USB/SATA bridge chips are poorly implemented.) This would be a sign of poor power, loose cable, or faulty hard disk.

It could be either a loose USB cable, insufficient, or unclean power to the disk drive (causing it to brownout with heavy access (db functions), or a faulty new drive (did you run badblocks on the drive before you started using it? (if you run badblocks now, be careful, some of its options will destroy existing data.)
