I bought several 500GB / 1000GB Buffalo Drives last month with plans to use them from Windows via USB. I attempted to do a lot of heavy file copying to/from them. I was getting a bunch of "Delayed Write Failures", I finally gave up. The 500GB drives had a single hard drive internally, so I opened the case, removed the drive and connected them via standalone external carriers I had around. In that mode the drives worked fine (from Windows). I've used both standalone eSata external carriers and standalone USB external carriers with these same physical drives with no issues. My conclusion is that the electronics in the prepackaged external units is just not up to the job if your doing heavy i/o.
