Doing a list of what hard drives do and don't work is a good idea, but honestly, I think that should be done in a new thread and this thread should be used to update people on what's going on with Bell and what they've been told by the techs recently.
Fact of the matter is, the 750 GB Neil Poulton design La Cie External Hard Drive is the one Bell recommends and sells, so that is the one that should definately work. If others work, that's great, but I bought the La Cie EHD so I want Bell to figure out how to make the 9242 work with that one, not tell me go by another one made by another manufacturer because they screwed up and can't fix their own problem.
In terms of updates, I called again this week and got the standard "We are aware of this problem and are working on a solution. We hope to have it solved as soon as possible, and ask that you bare with us as we adapt to this new feature." I never bothered to point out that they should have "adapted" to it before profiting from it, but did let them know I'd be calling back for an update in a few days.
