For nearly a year now I have a Lite-On LDW-411S and I had great fun with it,
without any real problems while using the FS0F firmware.
The only problem was that it wouldn’t burn some DVD-RW’s I have a spindle of
so I decided to do some firmware upgrading to the latest version (FS0K).
So I went to the Lite-On site and downloaded the official FS0K firmware installer
and ran it; no problems here: it gave me a fine message everything was okay
and I should reboot.
After a while the system was up and running again and I tried to burn a DVD-RW
(one that previously didn’t work) and found out it still wouldn’t burn.
Well hey, no big problem: it’s only a small spindle and they were cheap, so nothing’s
really lost, maybe something for my next DVD-ReWriter…
Until… only a few days ago I wanted to burn a DVD-Video from an image I
authored (which upto now always worked fine) using a DVD+R I always use.
But it came out as a nice little frisbee (there’s no real other use for it now).
This was the first coaster I’ve ever had using this drive!
Well, these things do happen, so I tried another one: same thing! @%#@$%
Another one, from another brand, also didn’t give me a DVD my player could
I’ve de-installed Nero and re-installed it again, but hey! Nero didn’t even see
the drive anymore!
So I swapped my DVD-Rewriter (which does still work as a normal DVD-ROM drive)
with a CD-Rewriter I have in my other (Windows 98SE) computer.
Now the problem was on my Win98 PC, so it’s really the drive that faulty!
My CD-ReWriter was normally seen by my first PC (with Win2k on it).
Now I went experimenting, because I didn’t buy a DVD-ReWriter to just use it
as a normal DVD-ROM drive.
I flashed it back to the original FS0F firmware (with help of some nice tools
but it still wouldn’t be seen as a DVD-Writer.
Tried the ZebraMod-thing and turned it into a LDW-811S, but it just doesn’t
work anymore. Period.
I’m affraid something went wrong while upgrading the firmware the first time
with my EEPROM, using the official Lite-On upgrader!, so I don’t have a backup
copy (with laser-alignment data in it, I know) of my DVD-Rewriter’s EEPROM.
Does anyone have a clue, how to turn my DVD-ROM drive back to a ReWriter
again, or maybe have some samples of EEPROM-dumps so I can go compare
EEPROM-values and work out the neccesairy bytes that are responsible for
letting my PC see the drive as a ReWriter again and not a Read-only drive?
Any help would really be appreciated.
