I purchased a 712A (Retail, boxed) 3 days ago and it is was working fine with Firmware V1.04. I sepcifically purchased the drive as it should have been possible to change the book type setting for DVD+R’s. After checking the Plextor website, I noted that I needed Firmware V1.05 to be able to change the book type.
I flashed the firmware (using the official Plextor updater) which reported success but now nothing works properly. If I do manage to burn anything, it is totally unreadable on any other drive and it has even rendered a DVD+RW completely unusable (I can’t even erase the disc). If I try and use Plextools to create a data DVD, I just get “Invalid Command Code 052000”.
I have been using PC’s for countless years now and have never managed to kill any bit of my hardware…especially when using official firmware updates! The V1.05 firmware has been in circulation since August 04 and if there were problems with it, I would have thought they would have been rectified. I have tried flashing back to V1.04 but it makes no difference.
Is this likely to be a firmware killing incident or has the drive just perhaps given up due to a fault somewhere?
Thanks for any ideas anyone may have…
