Thanks for your help, slipkid.
[QUOTE=slipkid;2772703]Imgburn says it is a HP DVD Writer 1270e HH22 (USB)[/QUOTE]
HH22 is the firmware version.
[I]I think the firmware is what’s written on the bottom of the drive on a sticker as “dvd1270e-H01a”.[/I]
That’s the model number. You have an iHAS224 A clone.
[I]Device manager gives no information about the firmware that I can find.[/I]
It might not be apparent, but it would be there. In System Information under Hardware > CD-ROM you could see the IDs for all your connected optical drives at once, with their firmware versions.
[I]Strangely it does say that the current region is “not selected”. So it appears not to even be set?? It does seem that it will let me set one (but of course “no region” is not an option).[/I]
It looks like your drive isn’t region-free yet. At least, I thought that if a drive had been made region-free, the option to set a region for it would vanish.
[QUOTE=blackened2687;2772715][B]Algol[/B], do you still have the original dumps from your [B]dvd1170e A[/B] drive? Could you please share them? Thanks![/QUOTE]
I saved the binaries. The drive is a 1170r with WH24 firmware. I could.
