I just got a SH-S182M and was checking it out for functionality. Tried an HP CD-RW (manufacturer id: Ricoh (97m27s00f)) and was able to read and write to it. Tried a Staples DVD-R (manufacturer id: CMC MAG.AM3) and was able to read and write to it. Tried a Fujifilm DVD-RW (manufacturer id: MCC 00RW11N9) and was able to read it, but when I tried writing to it from NERO I got an Illegal Disc error. Tried another DVD-RW of the same brand and got the same error. I tried using CDBurnerXP Pro but it failed also. Is this just a problem of compatibility with this media or is it a problem with the SH-S182M and should I consider RMA’ing it? I have made sure it is jumpered correctly, using an 80 wire cable and that DMA is on (although NERO seems to think that it is not). The media worked in the burner that the SH-S182M replaced in this setup (a Toshiba SD-R5112) so I don’t think it is a software problem. I did flash the SH-S182M to the latest firmware (SB04).
