I assume you have already checked bioctl and information in the ctrl-m utility for anything unusual? Here's one method: move the disks one by one to another machine with a normal SATA controller, either boot an OS from another driver (don't mount them) and check SMART status (probably useless, but you never know...) and try reading the whole disk with dd and look for errors/timeouts, or alternatively run the drive manufacturer's testing tool - you can usually find these by looking for the RMA procedure on their website. Should be safe, but I would not want to do this without the backups, just in case. :-)
