Now I am really disappointed. :a
I just phoned the German Plextor Support and described my problems with my PX-716A. Perhaps you can have a look at my burn results and help me to decide if my 716A is really defective, but first have a look at the really "interesting" story the Plextor Support told me:
The guy claimed that if I use media that is not on Plextor's lists of recommend or compatible recording media, the firmware forces the drive to develop a strategy for the media (and varies it from burn to burn) and writes it to the firmware (I asked why there aren't any AutoStrategy entries in my drive if that happens, and he said something about unknown manufacturer/media, didn't make any sense to me). And furthermore he stated that if I use not recommended/compatible media for extended periods of time, that will influence the reading capability (!) of the drive, even on original (=bought) CDs and DVDs, making the drive unable to read even bought (!) discs! He didn't say it, but it actually sounded like: "Using incompatible media will damage your drive and you'll void your warranty."
I mean... I've read a lot at this forum, computers are my biggest hobby since I was 8 years old, I've assembled countless PCs myself, I'm really into hard- and software, I am studying electrical engineering... Bottom line: I'm certainly not a noob. :bigsmile: I may be mistaken, but the story from Plextor Support sounds like total and utmost bullshit to me! :doh:
He was very impolite, although I was very polite towards him, after all, I wanted to RMA my drive, and in cases like that I'm always very polite... :bigsmile:
- Ok, and now about my problems with the drive. I noticed that burn results grew a lot worse recently. Until now, I tried only CD-Rs, because I don't want to waste DVDs and I don't have quality DVDs at the moment.
I bought 20 Verbatim Pastel discs, "Taiyo Yuden (typ. (type 1)". The Plextor Support told me that they are not on their list of recommended media. I said that Taiyo Yuden are on the list, and he answered that they're not manufactured by Taiyo Yuden, that Verbatim makes the polycarbonate disc and Taiyo Yuden only provides the chemicals. I can't say if that is true, but I don't believe it.
Well, as far as I know, my 716A should easily do a at least readable (!) burn on a Verbatim Pastel disc, even @48x, shouldn't it? It doesn't. Have a look at my first scan.
I tested some other media which are cheap, but in the past I achieved readable discs with low C1 error levels and only some C2 errors near the end, and now burns on them are unreadable with lots of C2s and even CUs (still the same cakebox!). I used PlexTools in case the Plextor Support wanted to see the scans...
Please tell me what you think and what I could do. :sad:
I will try to get some "recommended" media (even if it costs me more money... :a ), so he won't have that stupid excuse anymore...
