Please help me: plextor 482448ta

[akira.fudo]

goodmorning to everyone. I bought a Plextor 482448TA but I can't use it.
OS: Windows 98
Burn Software: Nero 5.5.1020; Record Now Max 4.5; Clone CD 4; etc

I can't erase CD-RW: it use about 1 minute but the cd-rw is not empty (I tried with the one in bundle with burner). The same cd-rw on other burner works correctly.
I get this sence: Power Calibration Error.

Well, i tried the burner on 2 more PC and i get the same problems (I changed OS in Windows XP, but the problem is the same).
BUT if i delete the cd-rw or write using the program in Windows XP (no nero, no Record Now, etc) it works perfect.

WHAT'S the problem? What can I do? PLEASE HELP ME!!!!!

Sorry for my bad english.

Thank you very much.
Akira
