I'm using jungleflasher and that recognises the drive so yeah I suppose windows does recognise the drive. When I first flashed 1.4 onto it from a stock drive I used firmware toolbox with no problems at all. Now I'm using jungleflasher because it worked flawlessly upgrading 2 benq's from 1.4 to 1.51.
What I do is turn on xbox, open jungleflasher, go to the hitachi tab and make sure all the relevant options are set and put it into mode b using the send mode b button. It says mode b done in the box at the bottom and has the usual giveaways that it's in mode b like 2 presses of the eject button to open the tray etc.
Then it come to 79 unlock. I put the cd in the xbox tray, let it spin up for a bit at then press the 79 unlock button which is when It usually says it failed to pause it or play it. Sometimes it plays, ejects itself and when it closes it says ram upload failed. I've actually had it say done once or twice but when I try to dump the drive I get a file with no drive key. I've tried Port IO and WinAPI and neither works. The drive actually shows up under the bit where you can select drives but it never dumps and most of the time it all locks up.
I recently tried to even dump the drive just in Firmware Toolbox but this time after getting it in mode b successfully again using slax I couldn't get the 79 unlock to autoplay. The only difference from when I done it last time is that I now have Vista on my pc, I'm gonna try going back to xp and see what happens.
