Hi and Welcome!
What drive and firmware do you have exactly?
I have tried to look on Samsung support site and HP as well.
Firmwares for retail drives (SH-W162D) and some OEM versions (TS-H552D) can be found on Samsung ODD websites (OEM versions mostly on their korean site). See the FAQ in my signature for links.
If you own a HP computer, then please contact HP technical support if you can't find any newer firmware on their website.
[quote]Any idea if any of these firmware revisions support bitsetting?
Most OEM firmwares don't.
