Oppo 205 compatibility issues with ext HDs

What brand external hard drive are you using with your Oppo 205? I have an Oppo 95 and before upgrading to the 205 I want to make sure it is compatible with a 'Pro Audio' hard drive. When I bought the 95 I tried two such hard drives with internal power supplies: glyph and avastor. The oppo 95 was not compatible with either, apparently because they used the latest oxford chipset. I asked Oppo support if this issue was resolved in the 205 but they wouldn't commit. All they would say was they haven't heard of issues from customers. So before I upgrade... what ext HD are you using successfully with your 205?
