I should have read the review here before buying this product. I downloaded the latest Raid Utility for Windows and it still cannot find the drives. I disabled the drives as suggested on the BuffaloTech web site and still cannot find the drives.I've been on hold for 40 minutes for tech support. This is the second call. The first call, I spend 10 minutes on hold, and then got hung up. It seemed like the company rushed the product before testing and probably too cheap to hire tech support people to deal with all the problems.This is my last Buffalo Tech product.
