Big problem here.. this is going to be a long one (I like to explain in detail to be sure I didn't miss anything important) .. so bear with me, cheers.
Discovered this forum recently. To be able to supposedly flash from 48x to 52 was very tempting.. so much so, that i did my research on here.. and proceeded.. flash went great... I did a couple of burns at 52x afterwards and it worked fine.
as of a couple of days ago i've started creating my first ever coasters.. I can no longer burn a CD WITHOUT making a coaster.. this is with media that I know used to work perfectly fine (I then bought other media that worked fine in the past just to determine if the media was a bad batch, and the problem was occuring with the second brand of media as well :eek:
This is the problem:-
Whether I be at 40x or 48x with certified media (that used to work faultlessly at 48x) ... The yellow (buffer underrun) light will flick on at some point during the burn and the cd will spin down.. it sits there for a while (up to 1 min) and makes the odd grind noise.. and eventually kicks off and continues through to the finish.... however what i am finding now is that the burner will burn fine right up to the 96% / 97% mark ... then the problem will occur EVERY single time... it just can't finish off a 700mb cd without this happening, regardless of media...
This has only been occuring SINCE i flashed the drive... i was concerned the flash was buggered.. so i flashed back to my original firmware... nothing has changed...
Also, this seems to have affected the 'readability' of the drive too ... as I can be copying a whole divx off a CD (tested in other cdrom drives to be perfectly fine) .. and the cd will spin down and grind to a halt at random intervals... eventually spinning up again and continuing on it's way... (sometimes coming up with an error instead.. stating "cyclic redundancy error") ... which brings me to the point of saying if i AM able to get through the bufferunderun section of a burn process, where the cd is salvaged and the burner is able to spin up the process to do the lead-out (which is very rare i might add) .... if i pop that CD into my trusty reliable reader drive afterwards? it gets to the point where the burner locked up with the burn process.. has a bitch .. then says the same "cyclic redundancy error" msg..
my burner seems to be totally rooted since i flashed it.. and now that i've flashed it back it hasn't made an inch of diff..
1) changed media, same problem (media that WAS working fine)
2) burn rate (whether it be 32x / 40x / 48x doesn't seem to help
3) readability of the burner now randomly buggers up as well
Last but not least, do any of you know if there is a Liteon distrubuter based in Australia? how would I achieve the contact details for this? assuming it's time to RMA :a
Any guidance would be highly appreciated here,
