Yep it's not sufficient. But guess what? It's the same problem and there's no way to even attempt to resolve it given that it won't boot to the old op system and also can't be seen by the computer. So it's back to the store for this guy. Take what I can get.
Question is.... is it just me, or do the 4 buttons round the wheel seem a bit cheesy? sticky? not up to snuff? Remind me of old 1970's Texas Instrument buttons vs. the HP's excellent never fail "touch". Not sure I'll get a Sansa to replace this... unless it's required.
