I've had a look on the Pioneer Website but I didn't find a firmware update that was explicitly meant for this drive. I contacted kenichi_tokudome@post.pioneer.co.jp who is listed at http://www.serialata.org/integratorlist12.asp as the Pioneer contact for that drive asking him about the problem and whether a firmware update was available, but I have not yet received a reply, yet.
