Thankx for so many reactions!
Well let me tell you a quick story on how my plextor px712 performs.
When I bought this drive (like a month ago) I just put it in my system and was ready to go. My first 2 burns were ok but the third went wrong.
I got a constantly buffer drop from my p712 ranging from 0 to 100% while burning.
As I was the cause, I succeeded in finding the problem (all thankx to this forum). I put the jumper on DMA on the back of the drive, which was VERY WRONG to do so.
Then I also discovered I had to use UDMA 2 for my plextor px712.
With UDMA 2 my plextor performed better. That’s logic!
The next problem I had was when I burned a DVD-R TDK 4x @ 8 speed.
I had back the problem with my buffer of my plextor px712.
I didn’t test any more but I guess I still have this problem.
He burns @ 8 speed but the results are not great.
PI of 80 while on 4x I only had max PI of 20. But I don’t mind speed!
I only want a good write quality.
Then I also discovered that when I burn a CD-R @ max speed (52x I guess),
I also have the problem concerning this buffer. My HDD can keep up with burning cause the used read buffer is always 98%.
Besides all that I never had any reading problem. When I read my burned DVD-R I have no problems with corrupt data.
Then I bought some VERY CHEAP DVD+RW from the mark Eron.
I burned one of these DVD+RW and did a PI-test. I was choqued (in a good way!). My max PI was about 20!! Sometimes the quality was better then on a DVD-R from TDK. But it’s dangerous to compare + and -. Those Eron DVD+RW’s cost about 1,7 EUR per piece. Well the DVD+RW from TDK cost over 3,5 EUR per piece. I guess you can get the picture.
I was thrilled to find out that my plextor could produce very good results on a low cheap media. I wrote those DVD+RW @ 4x, which is the max. speed.
So I read more and more CD’s I burned with my previous plextor PX8220 SCSI. All went well, until this reading problem.
That’s is in short my experience with my plextor. Remember that everything is ok. I have installed Windows XP SP2 completly updated.
UDMA 2 mode is enbaled for my px712. Why did the selftest took more then 30 min. to complete?? Should I get a new one?
I want to give a reaction on something gamefreak posted:
You say this DVD is crap. But why on earth can read an very old DVD-rom a crap DVD (with POF errors) perfectly? Also my DVD-rom in my G5 is reading perfectly. You tell me that the plextor px712 can’t read pressed DVD-roms?? So all DVD’s I buy (which are dual layered) won’t read???
Then please tell me why on earth ppl would buy this drive? You can’t even backup your own DVD’s! I don’t say NEC or any other mark is better but I can’t stop thinking of selling this drive and buy another! Anyway I will rent a DVD and will do a PI-test on it. If this is also bad (with POF errors) is my px712 damaged and defective??? If it is only this DVD that reads bad in my px712 I will buy that older DVD-rom to read from.
I’ll keep you guys up to date as soon as I have more info!
I have an Athlon XP 2200+ but I don’t see why that would give problems.
