Hi guys I am using SAMUNG SW-252 CD-RW to write the Cds The prob is whenever i am going to write the cds Nero giving me the massage POWER CALIBRATION ERROR. I do all Possible Tricks. I have updated Latest FIRMWARE. 1-Changed The media local CD r---->Samsungs Cdr------>LG------SONY. Nothing happens. 2-chacked on all writing speeds 52x.....32x.....24x.....16x......4x Nothing happens. 3- Tried DifferN Burning Softwares. AS* Feeling Like RIPPED. What the hell Is This. FU*K OFF ***SAMSUNG***. They Are Worst.
