[qanda]This thread is about the Plextor PX-810SA. Click here to see full specs[/qanda]As i can’t find any similar question here, i will post my problem how i can.
The problem is, that i can’t erase hi-speed cd-rw discs with my Plextor PX-810SA. The only information what i can give about these discs: Verbatim CD-RW 8x-12x and Acme CD-RW 12x, cause Nero InfoTool shows n/a in all fields with useful information. Btw, i can erase, write, overwrite any other media, like dvd-r, dvd+r, dvd-rw, dvd+rw, cd-r, etc.
I will try to explain it more detailed.
I was able to burn these discs for first time with Nero 7. Everything was ok. After 2 days I wanted to burn other data on these discs and then the problem occurred. I was unable to erase them, because Nero asked me to insert a rewritable disc and later i noticed that they are recognized as cd-r (read only) media. I tried this operation with ImgBurn, but without results (ImgBurn did an erase, but showed that media is still not empty). I was angry about that.
Now goes the interesting part.
I downloaded the latest firmware for my Plextor (v1.01) from official site. Upgraded it and immediatelly tried on these discs (without restart). As a surprise i saw them as CD-RW discs now in Nero InfoTool. Now they was erasable and burnable again.
Now in next day’s evening (computer is still running without restart) i am back from work and trying to erase one of discs… and again the same problem. Ok, i switch off computer, turn it on again. Windows XP (SP3) found new hardware… everything is ok and installed, but problem still exists as in beginning… i really can’t find any information on google about that because of my poor knowledge of english. Usually i can find, but not this time, because problems are so many, but not similar to mine.
P.S. I can read these CD-RW discs with no problem… and one more thing… Plextor can easily burn older cd-rw’s with 4x speed.
