What are you talking about??
Who did suggest that???
The suggestion was made by those who own other PowerFile changers similar to the one that I have (also made by PowerFile) and have tried to swap out the internal drive that ships with the unit for off the shelf models found in other PowerFile changers that should have worked. One potential reason given was that the internal drives may ship with a modified firmware for any number of reasons e.g. prevent the use of inexpensive off the shelf replacement drives or simply just for compatibility with the changer mechanism. It could just be one user got a bad drive and the question got raised a few times.
It sounds more like a little paranoia from you.
Nothing has changed on your drive! It's clearly impossible!
IF anything had changed to the firmware on your drive then it wouldnt work anymore.
No one is suggesting it suddenly changed, the question is did the blu-ray changer manufacturer (PowerFile) modify the firmware on the internal drive for some reason before shipping it. Even if this is unlikely it would be useful to prove the point and I can only do this easily with an original version of the same firmware from a standard off the shelf drive i.e. not one that ships with a changer (probably not a problem as very few people have these changers). As mentioned elsewhere in the forum it is not a requirement to modify the reported firmware version when changing the firmware code. It is also entirely within the realm of possibility that PowerFile could do this, as they undoubtedly created a custom firmware for the changer mechanism, so modifying the internal drives they ship to interact with the changers firmware in some way may have been of benefit to them either financially or from a functional view point. At any rate it wont hurt for me to check as if the changer gets broken for any reason it could be impossible to repair as PowerFile are out of business and the only agents were abroad meaning very expensive shipping charges and problems with customs fees.
