It is a Pioneer 105D recognised now as a Pioneer 106D. It isn't just Windows reporting it as a 106d the program chkrw reports as a 106d as well.
It has a writing problem as well, it reports a calibration error when I try to burn a disc. I was wondering if this could be a UDMA problem (the not burning disc one that is). It had been burning OK upto about 2 weeks ago, even when burning 2 copies of the same disc at the same time e.g. a cd in my LiteOn CD-RW and a cd in the Pioneer, and then it failed to burn the one in the Pioneer. Maybe this problem is due to me flashing it. The firmware version is 1.08 it wasn't a manufacturers firmware update, but I forget who's it was. I thought I was sure I'd picked the correct one. but when I looked on CDFreaks site the other day, I found one to return a 105 back to the original firmware but when I read the readme it was for a 106!!! so that had me thinking I could have used a wrong firmware update. Although with the one I used, the readme said it wouldn't install on the wrong writer.
There was also the copying DVD problem I mentioned in my previous mail, I couldn't get as far as writing to the DVD as it failed making the image.
