Recently, I bought a second-hand 411S. It was known to have problems with some media, as I was told before I bought it.
After installing it in my computer, I found that, with the media I tried, it doesn’t burn anything at all! That is, Nero is writing fine, but a verify fails. There are also problems with erasing RW’s. The problems apply both to CD and DVD.
The drive reads everything I put in it, CD/R/RW, DVD/R/RW.
I’ve already tried flashing the firmware to the newest version from Lite-On but that doesn’t solve the writing problem.
I’ve been searching in this forum, but couldn’t find a straight answer to my questions, so I put up a new thread. I hope someone can help me.
'Till now, I’ve come to the conclusion that I suspect that the former owner has tried to make the drive region-free with an unsuitable tool. So I downloaded an EEPROM dump somewhere, programmed in my drive using a tool that everyone has but noone should have (after making three backups of my current EEPROM, yes) and restarted my computer.
Yes, I am fully aware of the fact that programming any other drive’s EEPROM to my drive DOES destroy it, because valuable calibration data is overwritten, but what did I have to loose, having a drive that does NOT write at all??
To my great delight, the drive burned both a CD-RW and a DVD-RW (2 GB) and verified OK! But 'till now, I’ve only tried this two burns (no time for more extensive checks, no PIPO’s, but I will burn some discs and PIPO them asap), so I don’t know how the drive behaves at other media. I guess there WILL be problems, because the EEPROM was not calibrated for my drive!
What I like to ask to the forum members is:
Regarding I made an EEPROM dump that has problems, and I have an EEPROM dump that at least does something, is there any way of repairing my own EEPROM? Is there any universal EEPROM dump that maybe might not produce the best results, but should work in any 411? Or is there any calibration program that can recalibrate the drive and write the results in an EEPROM dump? (I guess when a program like that DOES exist, it also needs a calibrated, prerecorded DVD for good results, making this method quite useless to me.)
