[wplug] Ext3 filesystem errors with RAID 1 USB drives

As for the source of the corruption, as other people have said, it's probably a noisy USB bus.

After a fsck, the drive is fine for about 3 days, then the errors
start coming back. Just to give you some more details, I'm using a
dedicated PCI USB card for this setup in an old 800Mhz Compaq
workstation, and the RAID appears to be clean.  Everything is
connected to a UPS, so I'm hoping that the power is clean. I'll try
some of your suggestions.
