Having given up on a hardware/firmware resolution to my problems with this drive, I’ve been searching for compatible media (i.e media that will write at 8x).
I started a thread on the Toshiba support forums, where I was basically told to RTFM where I’d find a list of Toshiba recommended manufacturers. This I duly did; from the manual:
DVD-R: Taiyo Yuden, Matsushita Electric Co.
DVD+R: Mitsubishi Chemical Corporation, Ricoh Co.
So I visited my favourite media site (http://www.svp.co.uk) and have just spent Â£20+ on two spindle tubs of Verbatim media:
Verbatim 16x DVD-R manufactured by Taiyo Yuden, media code TYG03
Verbatim 16x DVD+R manufactured by Mitsubishi Chemical Corporation, media code MCC004
And guess what? No surprise; supported write speeds for the DVD-R are 2.0x and 1.0x, supported write speed for the DVD+R is 2.5x i.e. exactly the results I was getting with my previous media (Verbatim 16x DVD+R YUDEN000T03).
Googling, I found a list here http://atg.wfu.edu/technotes/dvdmedia/ but can’t find any of the compatible 8x media to buy it! Can anyone point me at some media that is both available to buy (in the UK) and will write at 8x on this drive?
Any suggestions appreciated.
