Bought this baby a couple of weeks ago. Its basically an OEM version of the LiteOn LDW-811s. I've now force-flashed the firmware so it now IS an LDW-811s.
Download a utility called FlashFix from HERE followed by the latest firmware for the LDW-811s from HERE. Follow the instructions on the FlashFix page and Bob's your uncle!
There are a couple of utilities from LiteOn which you may find useful. Follow the link from the firmware page.
No worries, Mitch. I can't take any credit for the info though - I found it on the forum pages of CDFreaks.com. There's loads of info and help for all manner of subjects.
The place where I got it from appears to have sold out. The drive is actually called a DRW-1S81 so you might have some joy if you do a search for that on Google or whatever.
Daz,
I've been using one of these for a couple of weeks and for me it has been faultless. I was bit worried it wouldn't work on my 3 year old 800AMD PC but it's fine. Burnt a few cheap DVD+R's and some dearer Ritek DVD-R's. CDR's are a breeze burning in about 4 mins.
If you can find one it's well worth it.
