Hi,

(posted this before in big bad "BTC Dual Format DVD Writer" thread, but a new thread seemed more appropriate after all)

About two weeks after I bought my BTC DRW1004IM (firmware 039, MediaMarkt in Amsterdam) it does only seem to read or write CDs/CDRs. Thats right, it even does not read regualr DVDs I have, let alone DVD-Rs. To be precise: when I put a DVD in the drive Windows Explorer shows it as empty.

I've tried the following things (according to the well known First Aid kit) without succes:
- Flashed firmware 045
- Tried the drive alone on secondairy IDE master or slave
- flashed my motherboard with the latest BIOS and checked proper BIOS settings.
- installed the latest drivers for my motherboard
- flashed firmware 043 (I recently noticed there was no 045 anymore on BTC's site, but 043, so I guessed perhaps 045 had some problems)
- kept fingers crossed a lot while flashing.
