Hi
That's surprising. It's the first time I've heard of a drive with bulk f/w.
BenQ's site still only list GSHB. This GSLB would imply support for Solid Burn.
Just been to site using your ref: the drive I saw was $69.99 & if the diagram was accurate then not a 1640 clone. Spec not the same either. Also had a look at HIVAL site & couldn't see a likely clone. Where did you get ref: for f/w GSLB. I couldn't see any ref: to f/w.
