[QUOTE=nirvana_1911;2480923]I have a Lite-On iHAS324 for reading/scanning and a Sony Optiarc AD-7240S for burning.
I’ve used TDK 8x DL, Intact 8x DL (cheap brand), and Ritek 8x DL, and it intermittently gives me “power calibration errors” on dual-layer burns only.
I’ll burn a half-dozen DL fine, and then the next few are all “power calibration errors”.
Next time I use my computer for burning, it’s the same story, some DL will burn fine, then the next few are coasters.
I have flashed the drive to latest firmware 1.03.
This happens with CloneCD, UltraISO, and Nero Express.
It always happens at about half-way, approx 40-60% through the copy process.
I have Windows 7 x64 Ultimate installed.
My power supply is a Thermaltake ToughPower 1200W W0133.
Any help will be greatly appreciated, if nothing fixes it, I’ll try to pursue an RMA on this drive.
Thanks in advance.
Have you tried burning these discs in the 324? I’ve found my 324A to be a better DL burner than my 7240. Have you tried a slower burning speed? The DL’s you’ve chosen can be troublesome for many burners.
