And somewhat odd because WDC are usually pretty good at USB-SATA bridge protocol compliance. But in any case this is unrelated to your problems. My concern was that our recent changes to the capacity detection in SCSI failed for your device. However, given your attached log it looks like it's a USB issue. And rereading your original log it also looks like you had a USB timeout which coincided with READ CAPACITY failing. So I'm deferring to the USB folks.
